Mossberg 590 SBS Review 

I'm watching this in July of 2024. I purchased a SBS mossberg 590A1 in May and the Form 1 only took 3 days to come back approved. Now is the time to get one if you've ever wanted one!

I think an SBS is just one of those things everyone wants. I've got a non-NFA "Firearm" in 12 gauge that I enjoy.

I also Form 1'd my Shockwave, added a Magpul SGA stock, Surefire fore end light, and a Meprolight tritium front sight(screw in). Magpul sells a butt plate adapter (for the SGA), allows for Remington 870 butt pads, I put a Limbsaver on mine. I can shoot slugs off the bench with that pad, without the pain.

That really looks surprisingly smooth to run. Really great video!

OMG…WOW!!! Just when I though Ive the best shockwave…I came across yours and you good sir…have the best shockwave vid on here!

Yes that's the best build I've seen yet

Man, you have all types of people who can handle the Shockwave with the birds head grip. Woman US Marshall's use them all the time.

I run the streamlight on all my shotguns and love it. Ran it through multiple classes and currently for duty use with no issues.

I have the same big dot on a 590a1 marinecote. Made it 100% more usable.

Over our years of working with the Shockwave, we at OPSol Texas definitely agree with "the feel". If you care to, get one of our Flex Adapters and run some minishells. Probably Federals are the stoutest. Nice video, thank you.

thanks for the info about the magpul forend not fitting. I was about to make the exact same mistake myself

I have one myself. Such a good little bush gun.

Hey man, I enjoy your videos. Appreciate your insight being a “regular guy” and not a former spec ops super hero. I love the looks of mossbergs NightStick model with wood. Practical wise I like the streamlight and maybe you can tap for a dot.

GG&G makes a nice pic rail light mount for these. Installs at the end of the magazine tube.

Nice! I keep threatening to SBS my braced 870 Tac-14 but haven’t gotten around to it yet!

I tune in every time my dude. One those views on each video is mine. Us Oregon folks gotta represent.

I like your idea with the flashlight. I would mainly want to do that and either Vang Comp or Mag-Na-Port it especially if I ever put magnum turkey loads in the tube.

You said something about stripping the paint off and add some wood furniture. I'm currently waiting for a 590 Shockwave and I'm thinking to do just that. I have (somewhere around my house) the wooden stock and pump that I took off from my 590 Retrograde. I do like the Magpul modern design, but at the same time I feel that some "classic look short barrel shotgun" is a must have in any shotgun collection. Keep that shorty beauty of yours as it is. But get another one and start a "Classic Shotgun 2023's project" 😉

I was just coincidently looking at red dot mounts for Mossbergs and fount that Monstrum makes a $20 mounting plate that bolts to the pre tapped holes on the receiver so you can mount a RMR footprint red dot. A Holosun 507c circle dot might be pretty good for a shotgun.

I've been going through sbs phase also... I don't know why because I like an 18 inch "tactical" shotgun but they're really cool so I might have to give in one day... LOL Great video as always keepem coming brother!!!

I put a Magpul forend on mine. It did take some mods but it wasn't that bad. I have a disability in my left hand so I really need a forward verticle grip, so putting the Magpul forend was nesessary, and of course it makes a great place for a light. I have everything filled out and I was just waiting on my ATF fingerprint cards to finish my NFA paperwork to put the Magpul stock on instead of the dumb pistol brace. I have a 590A1 with the Magpul stock and it is a great feeling stock.

I’ve been wanting to cut down my old 870 for years. I’ve just never done the paper work to actually do it. Great video I’m gonna go spend some money I guess lol.

I filed on a Benelli M4 SBS and it's my favorite shottie by far.

Go with the Wood furniture for much more adaptability of the gun, such as length of pull, and sling mounting. My 590 is std.18" Bbl marinecote, ghost ring&ramp, sling pnt. is on mag tube support under the barrel ahead of the forend grip perfect for a left handed shooter. I care over my right shoulder, muzzle down for ez transition to my left, to sight,and fire safely with 4 points of contact.

Sweet shotgun

*Slugs "nearly always" have some sort of wad under or attached to the slug... Yes, SOME wads are under and NOT attached to the lead. Some Wads are attached to the slug, somehow. IF you are making more holes than your number of shots fired... The extra holes might be made by 'unattached' wads.*

Great video! Thank you!

Great video thank you

Thank you, this was very informative. I recently brought this exact model home just over a month ago (after waiting 13.5 months for a tax stamp) and I am very happy with it minus one exception: it is difficult to find accessories for it because it is an SBS. For example, I purchased the Stream Light racker with the 1000 lumen light and was greatly disappointed because as you mentioned in your video, the racker is not a standard size because of the barrel length and therefore, does not fit. I am also having a very difficult time finding a full length rail system for this unit. Everything that I have found so far is made for an 18" or 20" barrel. I did however find an AR style stock with a buffer tube system that I installed which bolted on without any issues. (I've not tested it yet and I am hoping that it take more recoil out than expected...) Otherwise, it is a fun but punishing gun. If you have and manufacturers that make accessories specific to this SBS, I would greatly appreciate a few links.

Mossberg has a 590s model that cycles the 1 3/4" minis, 2 3/4", and 3". No adapter necessary. You can mix & match loads N/P

Nice 590 SBS sir I am looking to do the same soon

Crimson trace solves the aiming issue with the raptor grip

Good vid with one concern. The short shells are great however the shockwave needs an adaptor to shoot the short shells. Installed in the magazine well to properly feed from mag tube to barrel. Cheap and quick fix. Guys out of Lubbock Texas, I think? Now use 9 rounds instead of 3. I think that's the ratio? My shockwave/adaptor works well. First model adaptors came lose, not good. Next gen 2, like mine, worked well. Put some simple adhesive on it so it does not move. I cleaned everything good and applied contact cement both on the adaptor and mag well. Worked great, handled the vibration, dirt, etc. Easy to come off if you want to run full length shells. OPPPS... glad you covered the needed. Peace from Texas

GG&G also sells the Magpul foreend that is already modified for the Mossy Shockwave. I just bought one for my Shockwave about a week ago. it is about 20 bucks more than the standard foreend but you can find it under their Mossberg Shockwave parts section. only comes in FDE, Blk, or Grey.

Subscribed for more sbs videos. very cool.

Defender Tactical mini adaptor is a game changer

I've got a 590M and just ordered a 14" kit for it... Might have to do a video of it on my other chanel. Personally don't like the sling stud on the end cap. I took it off and screwed it in from the inside of the cap.

GG&G makes a Magpul forend they modified to work on the Mossberg shockwave.I too have went back and forth on a sbs haven't got one yet foresee it my near future.

Great vid. What chest rig are you running? I like those flip out shell cards.

GG&G has a Magpul pump handle that they have already modified to fit the Shockwave. FYI

I really want one of these but with wood furniture

i really like the streamlight racker

Since you aren't using the front sling mount, I'd throw on a +1 mag tube extension... it's not much longer, you get an extra round, and it can be used as an improvised 'stand off' device. Just use a good, tough one like the S&J Hardware or another seamless steel piece. Awesome sbs.

10:22 totally agree with that. I don’t like having to adjust my grip to hit the release. I have relatively small hands and the Remington release in front of the trigger guard is uncomfortable for me.

GG&G actually sells a modified magpul one I think for around 50 60 bucks

i prefer the mossberg safety to the remington as well. now that im on the hunt for a shockwave again i cant find one in 12g. no remington either. really like your sbs setup!

I have owned a shockwave for about 2 years now. I going to Form 1 it now also. Do you have any advice about the form 1 process? ? This will be my first experience with it and I’m not sure what I’m getting myself in to?…….

If you know a buddy who can run a lathe, I can give you the dimensions to thread it. I had my shockwave threaded for chokes. I reverse engineered the threads off my mossberg 500 28" barrel. Does yours require a 6 o'clock hold? Mine does and I hate it which is why it has a red dot.

Wicked. I want one.

Very cool shotgun 👍

Makes me kind of want one.

What is this OD green reinforced softshell you have? I can't find those ANYWHERE

mossbergs only shotgun worth SBS beside the M3 entry 😩 the 18.5 500 XS persuaders /tactical are cqb 👑 no hand to face any LOP shooting from cqb/vehicles, just take the shell saddle off and side Velcro it, med.classic limbsaver slip fits wrap edges w/etape for dismounts, cut/ZipT 1/4 pipe insulation for the best cheek rest 😭works great on Sub2k buffer tubes but most importantly KEEP THE STRAP!!!!! Most fights hand/arm hits common it adds no weight works as a vertical grip if needed

Does anyone know what shell holder he was using on his chest rig? Sweet setup!

Just saw you video great...I my have one...I am looking for a plus one or zero with the retaining ring sling mount. I am not willing to put anything under the barrel nut....and maybe red dot some day...Help if you can Thanks

Love to see you test federal flitecontrol 00buck 8 pellet at 30 yards. 40 yards and 50 yards with your sbs😊

I found the magpul mod easy, took me an hour maybe. I think it's worth.

Do you have a video on how you installed the stock ? And where did you buy it please

SBS my shockwave waiting for the mossberg ghost rings to be in stock.

Shockwave industries makes a nice M-lok for end for that firearm. $14.99 on sale now!!!

I think it"s worth it to form 1 590s shockwave, add some type of light mount, Optic mount or ghost ring , magpul stock, plus one(?), AND thread the barrel for chokes to get much better groups with mini shells. Ultimate truck gun and formidable hd weapon.

What was the overall length of it that you put on the form 1?

GG&G sells a Magpul forearm that is modified to fit the Shockwave.

Love your set up. I have tge Streamlight Racker. Bomb proof. Im interested in your sling adapter and sling. At least the name and links if possible.

I am getting one but putting a brace on it instead 🤠

Great video, can I get more info on the shell holder/chest rig you are running

I'd love to SBS my Shockwave with a Magpul stock, but I can't stand the thought of paying $200.00 for a right that I believe is already mine. I'm not going to violate any laws, so my Shockwave remains in "out of the box" condition, sling mounts and Opsol adapter excepted. Those mini shells are great. Good video.

I bought the Shockwave for a breaching tool. That and some bolt cutters. ;-)

U Need To Use Federal Flight Control Ammo For Ur SBS... U Also Need The Streamlight TL-RACKER 1000 Lumen Foregrip Light...

This video is awesome, thanks man! I have a Remington 870 marine magnum and I love it. I’ve always wanted a 590 SBS though .. might have to cough up the extortion tax and buy one too. I personally use a suppressed AR9 for HD, but I was thinking this would be a perfect riot gun for defending a storefront inside. Would definitely want some hearing pro though, this thing seems loud AF!

I am interested in knowing your thoughts on the 590A1? I'm a fan from Canada and we don't have that paperwork approval process for putting a stock on a Shockwave; which is surprising in a way because we have a lot more process and paperwork for firearms ownership than you folks,

i get not wanting a pistol grip (tho the birds head is pretty comfy tbh) however u kinda made it boring with the regular stock. i wouldve put a folding stock at least tbh... just to keep it compact. it still looks cool tho. the streamlight pump will complete it for sure. idk i guess the classic stock does look pretty sick with the short barrel tbh

Where did you get that front sight

How did you modify the front sight?

I want an origin 12 sbs or the AOW version without the stock.

What's the chest rig set up @1:51

I have a 590A1 18.5 bbl. Wonder if 4 in. Really makes that much of a difference

Did you buy your permit and then the stock?

Defender Tactical has a mini shell adapter that you don't need to remove to run both regular and mini shells

Beauty.

I think gg&g sells a modified magpul pump grip that fits the shockwave.

What chest rig set up is that?

GG&G sells a modded magpul forend just for that.

I always preferred Winchester Super X slugs they seem to be more accurate n my shotguns.

I have friends that work at Maverick Arms. I’ll be sure to see if they can speak to quality control to take care of the sharp edges.

I want to see that with a folding stock

Good evening. Maybe you can help me I hope? I am in the middle of doing a Form 1 for a SBS. It is a Mossberg 590 Shockwave. My question is the overall length it asks for in description? This gan in stock form is currently 26.5, but of course I want to put a stock on it like your is in the video, or something similar. Its going to be longer overall length when I ad new butt stock. Any way you could help me with this? Thank you.

I have a question. I Have a shockwave. I'd love to put that Magpul stock on it without feeling out a form , is it illegal to have it in my home or just to take out and shoot at a range?

That would be a great camping gun for sure

commenting for the logs

have the same setup but i mounted a red dot on it its fun to shoot until you get into high brass then the bastard punishes you i usualy put 20-30 shells of high brass before im packing it in for the day lol

2:24 🔥

fun size

Under what circumstance would you want to hit the pump release while still in your firing grip? I can't even think of a malfunction drill. 10:33 Great video.

What is the jacket you are wearing at 2:19? Where did you get it and how much was it?

What front sight are you using here?

GG&G light mount sling combo

How long before you got your paperwork from the atf if you don’t mind me asking.

All guns need a paint job. The black that most guns come from the factory is a primer layer basically. Ready for you to customize yourself. Black weapons stick out like a neon sign

What brand receiver sling mount is that?
