CZ 457 DIY Build That Changes The Game!!! 

I shoot my MTR and Anschutz off a bench only with myself or with a friend or two. It’s really neat the versatility of a CZ and the “build” . My health is rapidly declining but my shoot time with my son or friends is really still the best. CAMARADERIE!!!!

Josh.... Have you seen a difference in precision accuracy at 50 yards between the 16.5" and the 20" to 24" barrerls? I expect to see a difference past 50 yards, but I shoot against alot of other 457s and Bergaras with 20" to 24" barrels at my local ARA, and my 457 VPC with a 16.5 is on the pedestal just about every competition.

OTTA THE PARK HOME RUN AS USUAL #OUTSTANDING.... THE WAY U TESTED DIFFERENT BRANS OF AMMO REMINDED ME OF A OLD FAT GUY WITH AN EYE PATCH 🤔🤔🤔🤣🤣🤣🤣🤣🤣

CZ, Bergara platforms are both good platforms and fun to build on and your assessment of the CZ is right on. But in the end if we get serious enough in the sport we go full custom even if what we had was just as good.

keep doing the groups quickly like that, not that it was too slow before but its just super satisfying see the group quickly form like that, I dig it a lot! Also my cz 457 pro varmint has been able to do everything ive asked so far even hit a 4 inch target 2 in a row from 300 with it and cci std and a 100 redfield academy 2-7 once i get better glass its over

Barrels for CZ457s are, from what I’ve been able to see online, perpetually out of stock. Thankfully my stock pro Varmint shoots great. I’d love a heavy match barrel for better balance but I’m cheap! Maybe I’ll sign up for the MCR in stock notification and cry once they come back in stock as I still likely couldn’t afford one!

I placed in the top 20 in the PRS National Finale with my 457 and I don’t think it was the rifle holding me back. The balance issue is definitely the shortcoming, I have a 22” barrel, but it’s only .92” diameter and that’s the heaviest I could get. I needed to make my own weights in order to get the center of balance forward far enough to be viable because no one makes them heavy enough and even then it’s still not quite as far forward as I want. Maybe if I had a longer forend like an ACC instead of my Element, but I’m to cheap lol

I love my CZ but that mag relief is just bad engineering. MDT needs to improve that for the money they want for that chassis. Love this video.

I'd like more sako quad content....like how does the action compare to cz ,reliability ect..

Which trigger do you suggest? I found only Timmy trigger In italy

The overwhelming majority of shooters dont care if the gun is balanced in the manner which youre describing

Seems like you’ve gotten away from this setup. Is there a reason other than just doing different things? Thinking about buying this barrel, so if you’ve run into problems with it, I’d like to know.

Do not understand, you replace the action with Rimx, replaced the barrel, replace the stock, the trigger, then what is left that you still call it a CZ?

So you are actually taking a 457 CZ and tossing everything but the action and rebuilding the rifle so I have to ask why don't you just start with a full rifle of another brand. Is a CZ action that good

Re-barreled Bergaras with MCR chambered barrels are also available from Bison Tactical.

Have to ask what’s left of the original rifle considering the barrel change the trigger change chassis etc

Good video sir. Thanks.

What's a good social media app site for learning how to build my cz out?

Do you want to sell that modacam barrel????

there is nothing cz on this rifle haha almost everything is aftermarket

Popular yes but it will never outsell the 10/22

You can also go to Rectify LLC who can fit a heavy 1.15 or 1.18 straight contour barrel without cutting the deep notches in the chamber area to mount the barrel. A light press fit takes the stress out of the action, perfect headspace is achieved without shims. No need to send your rifle until he has the barrel in hand and they try to keep a couple Shillen super match barrels in stock. They have the aftermarket triggers and can also work the stock trigger to below Dave pull.

Please let me know where you got the bolt handle and the cheek rest.

Awesome video - jonesing for that sweet setup 🍻

What scope cam? This rifle is a dream!

I recently joined your community and really enjoy watching your very informative videos. If I may ask, can you give a break down of all the parts you used to assemble this setup and Can you comment on why the mirage cover and what is going on underneath the mirage cover? Thank you

Oh I like your videos. Great options. I am looking at the CZ 457. I have a MDT chassis under my 6mm Remington heavy barrel. It’s great

I would say it was the ease of the Clips that puts the customs rifles easier to work

I own a LRP the other side of the pond in the UK, shoot Eley Sport, NSRA Benchrest 😊 I've changed the trigger spring to a YoDave, may consider changing the trigger to a Jard

Thanks for the info I really like yours and Kenny's channel basically shoot ara and abra

Another great video. Yep balance makes the difference

Man those are at leat $3,000.00 nice!

what's your opinion of the Modacam vs DPG. is the juice worth the squeeze?

Started with the 457 Varmint MTR, shoots very well - then went with MDT LSS chassis, Yo Dave trigger spring - little more consistent, good feel ! Now what - full custom build ?! Haven’t been able to shoot PRS just local range. Will custom be more accurate at the 100-300 yard range ?

Love it! Should have mine in a couple weeks. Same as yours. Think I am going to try to make it fit my xlr element with c6!

Great Video. Question on the Modacam Mullerworks barrel. Is the barrel you used the same one they sell on their website (when in stock)? The reason I ask is because their website states "Mullerworks 1.180 straight taper. 25″ finished length with recessed flat crown." I think you stated 1.180 in your video, as well as 8 groove 1/16th twist - 24” inch barrel.

Josh , I just got my CZ Modacam back . Jon told me to double check to see if my mdt xrs would clear the barrel . I called MDT beforehand , they said it would fit fine . Well, you were right , they were wrong . 1” beyond the receiver needed relieved for a complete free float . The remaining 24” of barrel cleared easily without modification . Modacam is great to work with . I sent him my receiver to thermal fit the MullerWorks barrel . He also fixed my chassis for me . Those MullerWorks barrels ain’t cheap . But dang, I’ve never seen such workmanship looking through the borescope . Getting the chassis back soon . Thanks for posting this vid .

Talk about consistency, yeah the rifle is awesome, but check out the time lapse and you body positioning to the rifle. Same spot every time.. that is consistency... well done! Thank you for all the information..

Is there a way to get enough weight forward on the stock 457 MTR without changing the chassis?

Man that is bad arse. I have grey birch carbon 457 barrel i could trade you for a springfield 2020 hahah

Nailed it, exactly the reason i always shoot my rim-x over my cz. When i get a heavy steel barrel for my CZ, i may go back because i love how flawless my feeding is with the cz... Just cant find any match aftermarket barrels. They are never in stock! Ever!

Have you had any magazines and feeding issues with the bergara? Seems like i have seen some people with issues when put into after market stocks.

Ordered one last week from John👍 can’t wait to get it..

Nice '' Great Stuff 💯💥💥💥💥💥💥💥

How call part of yours chassis on te front above barell? Sorry for my english

Yea i think it shoots

I asked in another video, but what weight brand weights are you running up front?

As a general question how much can you change on a gun and still think its the same as when you started but there not much left of that cz 457 😂

Man the CZ shot very well even with the lesser quality ammo do you ever shoot Norma match with these newer barrels you been running ?

Balance on a CZ with a standard 20" barrel is tricky. I'm in the process of trying to add enough weight to the front end of a MTR in a MDT XRS chassis. I'm adding the heaviest weights to the M-LOK slots out front and then plan on mount a lead weight on the front "shelf" underneath the barrel that is made by my long-ish ARCA rail mounted to the rifle. Next step is to explore one of those heavy MCR pipes...

Will the MPA 457 chassis not accomodate the 1.18 barrel? That size barrel looks basically flush with the receiver, and it LOOKS like the MPA Hybrid I have would accomodate it. Wondering if I'm missing something.

I see you use the Tract scopes. Have you tried the Arken

Is the Varmint pro my best bet if I want an all around rifle that can take a suppressor?

You have the mtr and have a lilja barrel on it. Lol you are living the life my man.

What about the Grey Birch MFG chassis?

Where can i find the the site for those barrels thanks

yeah its great until you want to get magazines! oof

Not to mention you have a chord of wood on the rear of that wood stock.

@pursuitofaccuracy 50 yards is great, but 100 and 200 yard groups is what sets theses builds apart. Anyway you can get some video of that?

My Cz in the mannors stock with the 23” lilja balances perfectly also

Awesome video Josh very detailed with lots of info. Thank you

Thanks for another thought video!

Noice! I think another factor is you cannot just buy a CZ457 action, and then the barrel isn’t threaded to the action so if you need to do all those things you are more likely to use established Remington 700 style components and gunsmiths

I thoroughly enjoy your videos and wealth of knowledge. I wonder what you do for a living to afford all of these toys.👋

Nice video. Really liked the edit Josh.

Hell yea that thing shoots

What’s the chassis on that 457?

Which Timney trigger is that

The MTR has a match barrel, are the aftermarkets that much better? If they are that much better why even buy the MTR?

For what it's worth the MPA matrix pro clears 1.25" straight profile barrels.

Great video/content again as usual. I came back here because I'm desperate to solve my feed/extract issues with my 457 and I'm dumbfounded by all the coments about how great these feed, and the availability of parts (not match barrels). I have a 457 that I purchased used but with a new IBI barrel on it. Shortly after I got it I decided to sell my Vudoo because it was running just as well as the Vudoo and just as accurate. Of course as soon as I sold it, my 457 started having extraction issues. After scouring the internet and waiting a while on a list, I got hold of those Volquartsen extractors and that solved my extraction problem instantly. However, I also instantly started having feed issues! I routinely hit resistance loading rounds (several brands/lots that all used to feed well). I have a whole collection of rounds with these crescent-shaped divots in the nose of the bullet, and also some crescents I cleared out of the chamber and mag well after a match since under the clock I was forced to rm a few of these guys home. I tried new aluminum mags from L3I, no help. Back to the CZ factory polymer mags, no help. I even replaced all the mag well components with DPI aluminim stuff, replaced the barrel grub screws, action screws, triple checked all the torque, and last weekend I was still having trouble. Accuracy has gone down the tubes as well. I really want to make this CZ investment work, and every time I look at RimX or whatever, I find myself back at your site for inspiration, lol. But I am running out of ideas and things to try, here. For now, I'll be happy to run a single 10-round mag through this thing without issue. Dry-firing and just dry-cycling rounds, it seems to run well. But back out at the range, it usually doesn't take long for the games to begin. Any ideas?

Where does that prefit barrel come from, please?

This is great info! Thanks!

DAMN!

Will it shoot is SECOND! COST is first

MPA Matrix pro chasis fits a 1.3...

Great video Josh. Love my CZ 457, my only short coming is the weight, I had to add 4mdt weights in the front, and since I do not have an ACC chassis, I’m still short to balance it out. I’m thinking of adding a 419 grip changer so that I have more weight in the front to balance it out.

What is that bag rider?

What ammo family does the JGS chamber prefer?

I put a weighted Arca rail.on mine like I have on my PRS 6GT one Manners stock and it fixed the balance issue

The most popular rimfire? What about the Ruger 10/22??

First.

You’re making me miss my 457’s now 😢 I just got rid of them within the last month since I never shot them anymore now that I have the vudoo

My T1X in a SCSA chassis and lighter trigger can do those groups all day with SK rifle match @50m. 1/4 of the cost of that build brother 🫡
