FX Maverick .25 (Review) + TUNING GUIDE !! + FULL SETUP + Accuracy Test !! - How to Tune an Airgun! 

Link to my Maverick Tuning Notes & More at the AGN Forum: www.airgunnation.com/topic/watch-discuss-the-fx-maverick-element-titan-and-more/

2 years later after this came out and I am thinking of purchasing a Maverick tomorrow. I find your tuning guides very helpful & very thorough. I watched your air Venturi before I purchase that air rifle and although I already have avenge X Tuning guide. There's always stuff to learn/get better at so thank you. You've taught me how to tune my air rifles.

Thank you Sir for taking your time to put out this great information for new fx maverick owners. I am sure it will save many people time and frustration with this go to guide, best explanation on tuning i have seen yet. Thanks for your work.

I waited until I got home to watch this on my 65 inch curve screen. This is a excellent review. Your quality is unmatched. I think I will purchase this in the VP, or compact. God bless you brother and your family. 🎯👍

I purchased a .25 Maverick Compact from SPAW (Southern Precision Air Weapons) and I must say what Steve is illustrating is spot on. This compact performs accurately and smoothly and mimics its 700mm accuracy in a short compact version.

Sir this video is pure gold. I bought a used FX Maverick .25 Sniper with STX Slug Liner, Optisan Optics EVX 6-24×50, 3 magazines, extra 500mm barrel kit barrel kit and Donny FL Fatboy1.0 moderator, oh and I had a carbon liner added for free. All for $2100. I think that a FX slug power kit is probably installed as well. But I will get that confirmed. For pellets I will tune the 500mm barrel. It’s genius actually because whomever owned the air rifle before me considered both slugs for long range and pellets 100 yards and under.

Yo Steve! I’ve had to watch this video 3 to 4 times to completely get this information. I appreciate it even more each time I watch it.

But a very special shout out to you kind sir. For putting this video together. You my friend have given me the information needed in order to properly own this rifle.

I put my brand new maveric sniper exactly set for your recommended settings for the fx 26 grain slugs, and it has that tuned sound and is hitting on point! 13 squirrels down the first day, with just your settings. THANKS FOR YOUR TIME! MUCH APPRECIATED! RICK.

Hi guys, I have to get this off of my chest. I’ve watched countless hours of other RU-vidrs like Matt Dubber, Gerhard, Earnest Rowe and Ted’s Holdover. Truthfully I’ve learned very little from those channels as they are competition shooters and guard tuning advice at all cost. Steve has saved me countless hours by explaining the FX Maverick and the FX impact. Steve if you read this comment two things. Please revisit the valve adjustment on the M3 and make another video that explains it clearly. Because on your FX impact video we were all confused. And if you get the time we would love a similar video as this one for the FX M4. Thanks in advance

I just figured out why there's no pellets, Steve has them 🤣😂 4 testing, 5k pellets through the maverick

It was my pleasure meeting him and his wife at RMAC. They are the power plenum and power block couple in this field😏. Thank you man for taking the time to talk to me.

Always the best review on RU-vid 🙏

Massive work there Steve! 👍 The quality of this review is amazing! Lots of informations and tips! I see that you take great time to do all this for us and it’s very cool!

Fantastic work Steve! I have a newly purchased Maverick Compact .25 cal. Can’t wait to try out the 25.39 tune! Can’t believe the reg is set so low yet it pushes at such a good speed! Incredible!!! I’d also like to see if I can shoot the hybrid or the NSA 26.8 out of the Compact as well. Any recommendations on the reg settings? Is it even possible to have one reg setting and use the power wheel to adjust between the pellet and the hybrid (or NSA 26.8)? Thanks in advance! Keep up the great work man!

Wow, the information you are sharing with the community is staggering. Truly impressed by your work! Thank you so much, Steve!

Whoa Steve, that could be your best video yet! So much great information that almost any Maverick owner will be set! You’re saving a lot of people, a bunch of tuning time with all of this information. Props to you, I know it was a ton of work! Thank you! Stoti

Keep in mind when tuning your air gun that the more power you want to make the harder it will be to get sub 10fps ES’s. My marauder and dreamline are 5-6fps ES making 40 and 45ft/lbs. my 80ft/lb impact is usually around 14-15fps ES. If I pull the power out of my impact I can get the ES even lower than my other two guns. What a great sport/hobby, AEAC bringing the big brain again!

Another home run Steve! I have the Maverick Sniper in each of the 700mm configurations, .30, .25, .22. I just got around to setting up the .22 and literally followed along allen wrenches in hand and was able to set up a great tune for the 25.4 Redesigns as well as the 18.13 JSB in a matter of about an hour (slow learner I guess)! by following along with your tutorial...Your write up on AGN is fantastic to be able to refer back to general steps in the process. Your Crown Conttinum video was my first real foray into custom tuning and was blown away by the results and have used that as a guide for my MK2 Impact/MK3 Wildcat tunes and this Maverick tutorial is a great lead in to the M3 Impact setup as well... Great work and very much appreciated. Dr. Mike Long

Hi Steve, great as always, if possible, do a full review of the FX Impact M3.Thank you.

This is a “Grail” level gun. There are a lot of people that do reviews, but I have to say, none give as much information in an enjoyable/non boring format as yours. Keep up the great work! Is there any way that you could do a review on the Benjamin Akela?

Steve great to see someone finally dispel the myth of velocity variation, a spread of 25 won't even give 1/4 moa but a damaged skirt will. Am curious to know if you were using the heavy hammer from the slug kit or the stock one. From what I have found if the heavy hammer is installed you have to greatly increase the reg pressure or the valve is basically knocked into next week. That said , with one ,165/130-140 seems to work well as an all round tune for pellets and up to medium slugs from the Superior standard liner . The higher pressure producing more energy with less air thus the shot count is still retained and an accurate harmonic tune can usually be found with the power wheel for each projectile. One thing that might have been worth covering is how the fine adjustment screw actually works. If you extend it much past 6mm you have a high probability the gun won't cock and if you have it in too far you will have no additional pre-tension on the first couple of power wheel settings ( velocity won't change as your increase PW value initially). Also the Friction grub screw has a tendency to come loose and fall out of the hammer fine adjuster assembly and some weak locktite is well worth a dab. Its the one area that the manual thoroughly fails to cover, giving neither the OEM length or guide to the max length. Sorry if I'm being a boring geeky ar*e

I can’t wait for the other video I want a maverick so bad

hi thanks for your video. I have now found the perfect setting for my Maverick Compact cal 25 thanks to you. reg 1 - 130 bar, reg 2 95-100 bar.jsb 25.4 gr. I now shoot for 270 ms and it is effective with the air. it took many shots before I got to the right position. the difference was to screw very carefully on the internal hammer screw. then shoot from position 4-7 to be able to set the hammer screw again. repeat it again until you were satisfied. grettings from sweden

I am running 29 grain nsa slugs at 1020 fps with 175/150 on the regs. I was able to achieve this power with the second regulator at 135 or 140 but i found increasing the reg but lowering the hammerspring tension to get the same velocity was more quiet, the shot appeared less violent and accuracy improved.

Thank you so much for this video!!! My Maverick is showing up tomorrow, this will be my first PCP and I am excited to start learning, this is base for me to start with.

Thanks for all your hard work and sharing it with us

Your job in all of your videos is amazing. Thank you Steve

Steve how are you this is a great video Know why? I was In the market for FXM3 and they’re delayed 3 to 5 months so I looked at the day state delta wolf and you have to get on a list for that one so I decided to go with a maverick and now you’re putting out this video perfect timing thank you have a great day

Another wonderful video!! I cannot thank you enough!!!!

To me the maverick is the best bang for your buck air rifle on the market. Sure it’s expensive but you get what you pay for.

Thanks this shortened my time ,trial and error and pellets use.

Dude ubsaw how long this was and I was like no way I'm sitting through that. Well I sat through it and loved it!! I have a .25 Maverick Sniper and I absolutely love it! Will be replacing my older gages though!

please make one for fx impact m3

Thanks Steve , this is great Work !

I was wondering where you have been, now I know ! GREAT information as always, but being a Maverick owner, this one was special for me for sure. You spent some serious time on bringing the BEST information available. Thank you for your dedication to the sport. As always, I look forward to the next one ! And your dog filling in while you where away was a special intermission . :-D ...

Man you are the best. All your reviews are very detailed. I just order the maverick vp in .30 cal, what regulator pressure do you think will work the best. I want power but at the same time shot count and accuracy. A combination of everything if it make sense. I will be shooting the fx hybrid slugs 44.5 grains. Please keep doing those reviews I wish I was your neighbor lol. Thank you.

Outstanding content! Studying up, in anticipation for the arrival of my new .25cal Maverick VP, this coming week. Thank you so much for doing this!

Hello Steve, thanks for the detailed tuning guide. When you say 0 on your IHS, are you literally turning it all the way clockwise until it stops and leaving it there? And then all your adjustments start from there counter clockwise correct? I have the Maverick Sniper version and am seriously contemplating getting the compact barrel and bottle. Those STD Dev. Spreads are amazing on the compact! Thanks again for your info, that is a lot of time you are spending. I’ve done half the work as you testing tunes for slugs and accuracy tests and it takes hours!

Ok so this is very helpful video... but biggest question I have is how do you know when to adjust the hammer spring and why ???

Big thank you for a great instructional video, exceptionally helpfull. Just a querry with regards Internal Hammer Spring setting - how do you determine 0 point?How do you determine the max/ min setting? I take counter clockwise increases the tension- FPS.

Thank you, Steve, your video is a very education for the beginner like me, can you please share also if you have tuning guide for .22 call.

We live in Florida, so 25 yards isn't a waste of time guys who say Steve is wasting time at that range...squirrel, rabbit, racoon,turkey, or quail you can easily find those at 25 yards or closer...

I just watched this entire video. Do I own a maverick yet? No. When I buy one, will I Watch this again with it in my hands? Yes. Do I need a great deal of help psychologically and with tuning my gun? Yes. Ps, this isn’t the first of your videos I’ve watched. Thank you for your time and all the help. (That I will need when I have the gun) I’m leaning maverick sniper 30 cal. Maybe buying a 22 conversion down the road if I need to.

I got my Dreamline Tactical .177 to a point where my 22 shot string was average speed 902, spread 7, STD dev 2.0. With 10.34 gr JSB Hades. Reg at 100bar, Transfet port Medium and hammer spring adjuster (neutral cam) at 4. At 40 meters CTC was 20mm. At the moment I'm pleased, but interested, what other pellets would do. I tuned my gun for Hades, cos it is my go to hunting pellet (pigeons).

Thank you for these informative videos. I just received the new Wildcat MkIII BT sniper. While I need to shoot if before making any decisions I was a bit taken aback that the rifle I ordered with all the slug attachments/kits and an assortment of mid 30gr slugs was tuned by the seller for 25gr pellets with 910fps at 5 on the power wheel. When going through the owners manual looking at these adjustments I was surprised to see the book doesn't match the rifle, for some reason the manual for the Wildcat has reg adjustments for the Impact M3 and they are no where near the same in how the adjustments are made. The tuning vid FX has on their channel doesn't match these new rifles either. After a little research it appears that the Maverick and the BT sniper are using the same or very similar style dual reg and 89cc plenum set up. This video may be very useful in the near future.

Fantastic info and explanation for a neophyte like me. Thank you.

This guy is legendary

brilliant vid Steve

Steve loved your video and all the work you put in to inform us on the tune of the Maverick .25. Watched it like I was back in college and my professor was giving a lecture 🤣 but I have to ask, is there any way you can do the same for the Wildcat Mk3 Compact but in .22 caliber? I know that it's actually a Maverick but everyone on RU-vid for the Compact .22 say 1rst reg 180 and second reg 150. Which shot count sucks and the gun works so hard with for me making me think it's not harmonically tuned. So Professor, if you have or get the time we who are loyal students 🤣 would appreciate your feedback, input call it whatever you like🤣 but please do share since everyone is only tuning .25 & .30 cal's and the little guy is left behind the class 😢 once again I, we, thank you for all the time and hard work you put in all your video's and can't whate for the next one.

What happens if you tune the 2nd reg under pressure?

Man Steve, you sure put on a great review....I will admit I didn't jump on the Maverick band wagon but literally took the exact setup process you mentioned and applied it to my Impact M3 and spot on! I am by NO means a tuner but if you just follow the steps you lay out it makes me look like Ernest Rowe (ok, maybe not but you get the idea)!! All airgunners should take note as you have the initial 98% laid out and a bit of trial and error and it just comes together... Damn fine job. Dr. Mike Long

When will 30cal pellets be available? Or where can we get them.....kalibrgun 25cal or this maverick..it wasn't available at the time so I bought the uragan 30cal, super accurate..good video and information as always

Awesome video! Thank you. What bipod is that (maybe I missed it)?

Somebody get this guy a M3 NOW ! !

Another great job Steve!!!! I purchased the Wildcat MKIII 600 mm VP in .22. It’s pellet on pellet right out of the box shooting the FX 18.13. I’d like to try the FX 25.39 gr. Do you hav any suggestions on the velocities?

Great videos Steve!!! Ever thought about doing a tuning video on the .30 cal Maverick??

Great video Steve and thank you! It really helped to connect the content from other sites/channels. It sounds like the M3 tuning could land the same time mine does. 🏁

Badass top notch video ! An instructor at his finest ! What do you do for a living ?

I always love your videos, Steve and it's great that so many people ask about your new eyes !! Did you see that one come coming ? Pun intended. BTW, I went to the range today with my Hatsan Nova Star 177 w/ 16.5 grain JSB Monsters and I was getting bullseyes all day, but not quite pellet on pellet. You make it look SO easy !!! EDIT : I've never seen you do a nearly 2 1/2 hour video !

Did you pre adjust the micro adjuster so that the macro adjuster did start to put tension on the HS from position "1" and so forth, and didn't have any slack to start with? I've seen videos when the macro adjuster didn't start to put tension on the HS until you reached "2" on the macro wheel.

Hi Steve my mystery gun was a BSA Airsporter, nice .AIr Arms didnt understand what i was asking about ?

GM Steve I just purchased the Maverick in .30cal. So I … Need … Your Help Sir. Internally I added the (Tungsten Hammer) I still have the (Stock Spring). Gonna be Shooting the Varmint Knocker’s 50grn slugs, and the FX Hybrids 44.5grn slugs. In your Learned Opinion, what would be the Best Tune …. With A Decent Shot Count ??? Thanks Brother …. Looking Forward To Hearing Your Answer.

I want to be able to snipe an egg 100 meters away with the Dreamline Lite 25cal. Please tell me how I should tune it.

Steve really nice video, one quick recommendation is to use RU-vid Chapters, so we can quickly jump from section to section. Thanks a lot for putting this together

So at the top of each tune chart we're is says bar... is that what Steve is only filling the gun to for each tune?? If so I thought your regulators took care of the tune... so why not just fill the gun each time??

Is there a difference between the front gauge and the back gauge on the Maverick? Are they interchangeable? If there is difference, what is it?

Great video thanks Steve... you do a great job.. even if you geek out and we struggle to understand some thing at times... I have a question.. I'd like know.. is the maverick way better than a crown.. and are these more complex guns like the maverick going to be more prone to break down problems? As we don't ever realy hear anything about the failures

Steve, I bought an FX Dream pup and the regulator pressure adjustment valve is partially covered by the stock, not allowing me to make adjustment without removing the stock. (which is what the tech at Utah Guns told me I have to do) When I asked if I could us a rotary tool to cut away just enough of the plastic stock he said it would probably void the warranty, I asked if I could turn the cylinder enough to allow access he said it wouldn't be sealed properly, WHAT do I do? Should I just leave it alone?

Steve, first things first. THANK YOU for doing what you do. I've done a lot of tuning and I can't help but appreciate what you are doing for so many. On this video, would you say it would apply to the .22 cal? Do you prefer the .25 over a .22 for iguanas and why? Thanks again.

I was hoping you would do some reviews on the slugs that weigh 29 grain and more

Great job thanks

Thank you so much for this video I was having trouble with my Maverick getting it zeroed I had too many flyers after watching your video my rifle is now shooting lights out I can do 10 pellets the size of my thumbnail

Hi Steve, In talking to RapidAirWorx about the R.A.W. HM1000x LRT .22, they said it comes tuned to shoot a 25.39 grain pellet at approximately 960 fps. My friend bought a BRK Ghost .22 HP that came from the factory shooting a 25.39 grain pellet at 973 avg fps. He has since brought it down to 960 fps and it is a laser. And I just watched a RU-vid video on the Skout Epoch where it said you would get your best .22 groups shooting a 25.39 grain pellet between 950 and 960 fps. What’s up with the 25.39 grain pellet in .22 running 950 to 960 fps? Can you suggest a tune for my FX Maverick .22 Sniper 700mm to shoot a 25.39 grain pellet between 950 and 960 fps so I can see for myself? Thanks!

Thanks for your input.. I just recently got a maverick… now it time to adjust the trigger…and I can’t find a vid to assist me….. I’m hoping you’ve done a vid on that topic….. Thanks

Great work Steve! I've learned a lot from your video. I have the Maverick .22 compact but I've noticed that i couldn't hear that sip of air between shots, is there something wrong with my gun? Reg 1 at 140, reg 2 at 110, thanks

Just bought and waiting for my sekhmet I take it that you have to degas the gun first Steve,be nice if you showed a vid on how to install one as there is no vids on RU-vid on how to.thanjs for your hard work and enthusiasm keep up the good work.👍🇬🇧🇬🇧

Please do a tune for a lower power .22 fx hybrids 22gr for farm yard pest control

What would you set the maverick .30 700mm barrel at for shooting fx 44.8 pellets? First and second regs for starters, I know it will need fine tuning. It was set up for compact, then I pit a 600mm .22 now I'm wanting to set it up for .30 sniper!

Hi Steve,i have a MAVERICK sniper on .22, all perfect until now, when ever o shoot now, a massive air flow hits my face and wont go truth the barrel, checked valves and oring, and even lubed them and the problem is still there, any idea what it can be? Thanks alot!!

Steve I've see guys now shooting slugs to 1100 fps with crazy accuracy... could you try this for your fans and see what results you can get with the maverick... in 22 and 25 please 😅 will the maverick go that fast?

I was going to say some things about the Impact but I figured I'd better not do that since I'm going to buy the another FX gun. The Impact is a complicated gun it's a lotta work but I did shoot it the other on 15th of July, & it kept most of the groups within an 5/8-3/4" and 1"-1.25" with the 700mm barrel. That's really not that bad I was shooting @ about 28-30 yards. I was also using the Donny FL moderator it was an unmarked moderator. Meaning It doesn't have a name like "SUMO" written on it. By the way I will buy another Moderator from Donny FL for my 600mm .30 cal barrel; asap. The Donny FL moderator is working great; when the Impact still holds 3/4"- 1" & 1" - 1.25" groups; w/ moderate winds.

Tnx very helpful... keep up the good work

Hello... How can I get copies of your step procedures for the tune process sequence?

Thanks for the vid very interesting. I do not have a Maverick but I wonder if this mid level settings will work on my M3? I might have to give it a try.

I remember a promise that the FX Impact M3 tuning guide would be coming in WINTER of 2022 *::Checking Todays date::* 20 days til Summer =)

What kind of airgun shoots longer and is more effective at long distances. Fx3 impact or Fx Maverick (sniper) Can you answer me honestly about that. It is incredibly difficult to get an honest answer from those on RU-vid who have posted videos about FX 3 Impackt and FX Maverick. I need to shoot 300 - 400m to kill with cal 25 or cal 30. Which air rifle of the two is better for 300 - 400 m shooting. Maverik can be regulated, they say, and Impackt can be tuned, so what should one choose for 300 - 400 meters in cal 25 - 30??? Please give me an honest answer so I don't buy the wrong one. I have tried shooting with both at a dealer, but it was only at 50 m and there was no difference between the two airguns. 

Love it! I'm waiting for my .30 cal compact. No luck for a tune on that one, huh? Will be shooting Hades for hunting.

Hi Steve, Thanks for the great work! I must have spent hours watching your video's… :) Forgive me my ignorance, but is IHS the fine adjustment setting for the hammerspring? And if so, what's the take-off point? It being turned all the way in? If so, I'm definitely going to try out some of your tunes. I've tried several different slugs, but it's been really frustrating so far. Kind regards, Bob.

You didn't talk about the 2 transfer ports. Were you using the slug port for everything?

Great learning experience Thanks for the hours of effort Saw you were using the Labrador. I believe it charts theFPE at various distances Would like to see a chart in 10 yd increments out to 100 yds.THINKING 60FPE AT 60YDS WOULD BE GOOD FOR COYOTES?? THANKS AGAIN I-LEARNED A LOT TOM

Great video! Did u mic. The micro adjuster to see what it was set at from factory?

I’m thinking of getting the maverick, any new stuff that has been done to date. Thank you

1:05:29 you say; "open Clockwise" if I'm not mistaken, you open the reg counter Clockwise and that is how you are showing us a few seconds later. Or did I misunderstand that?

Hello, can this tuning guide apply to the Wildcat mk3 bt vp?

Please do a tuning video on FX M3 .22

Is this setting applies to all cal.???

How did u make those graphs ? What software where u using ?

The Wika brand is German and was established in 1946. Other than that, yet another great video! 👍

Still a great video Steve
