Hey all, just joined the forum. Im sending my paperwork in today to SBR my 15-22. Anyone have any problems with loss of recoil pressure doing this?

I just got mine running perfect, so Im hoping it stays that way.

A couple guys have posted here about their SBR 15-22's. I don't remember reading about any cycling issues. Hopefully they'll see this thread and offer any tips they might have. I think one had his barrel cut down to 6in. What length will you shorten the barrel to when you get your stamp?

welcome to S&W. glad you are here.

I believe the pistol version cycles with the same bolt setup, much like the 10/22 Charger pistol still works with a fairly short barrel.

So as long as you're not dropping too far under 10" I think you should be fine.

I would love to see a picture once your done. I day-dream about getting an NFA stamp. I want a suppressor the most! Second full-auto and third short barreled rifle. Surpress my M&P 15-22? Yes, please!

Keep in mind NFA items, other than registered machine guns, are difficult to sell once you tire of them. A silencer that works with several firearms has utility of sorts, but even these are normally just "show off" items to impress your buddies at the range.

SBRs have even less utility especially in .22LR.

As a demonstration of disposable income they pale in comparison to Shelby Mustangs.

Who gets tired of shooting suppressed .22?

I'll be sending off for a SBR tax stamp soon. The idea here is to reduce length to make up for the added 6'' suppressor. I think a suppressed SBR 15-22 is an ideal range toy and pest patrol rifle.

SBR cost? A mere pittance compared to what I've already spent-- There's close to $1500 in the below pic. Once you've reached this stage of insanity... well... uh... er... um... there's no turning back.

As far as showing off to others at the range... nah. As I turn the corner going down into the Plinking Range... sigh of relief... no one else here! Nothing will ruin a suppressed range outing more than some guys shooting obnoxiously loud S&W centerfire revolvers.

This pic is just screaming ""Please SBR me!!""

do you SBR guys plan on keeping the factory handguard?

I definitely wouldn't tire of a supressed .22lr or 9mm. I'm in love with the sound of it haha, I don't care if it gets other people's attention or not. It'd be very useful to have one for the handgun in case I'd have to use it inside a home.

My 15-22p appears to have a lightened bolt compared to the rifles. I'll try to get a pic on here tomorrow.

got yours running perfect and SENDING IN the paper work are not words you need to be saying......

putting the pistol upper on the rifle lower, without the proper paper work, is a felony....and basically admitting that on an open, public, forum is very much an unintelligent thing to do.

ATF and the like DO browse gun forums, way more than you think.................

My plan is to cut off 6.5'' of barrel and about 3'' off the factory handguard. This will give it the look of the original 15-22 ads but just a little shorter.

GSRswapandslow, I think he just got his rifle running right and is concerned about how it will operate when he gets his paperwork back and then cuts his barrel down.

GSRswapandslow,
Read it again. I think you misread what he was stating.
Today, his normal 15-22 is running flawless. He is sending his SBR paperwork in. When he gets it back and does the SBR, he hopes it doesn't negatively affect its operation.

well lets hope so.......i read it more than once, and took it a different way than you, which happens. I just don't want someone to unexpectedly get a visitor with the intentions of removing his guns from him, for life, and sending him on a 15 year vacation. It does happen.

10-4 on that. A stay at the old "grey bar hotel" isn't what any of us are looking for.

Yes, your right, I was having ejector problems and finally got it running great. This is my 2nd SBR. So no, no cutting of the barrel will happen till I see that $200 piece of paper.

I plan on cutting down the stock handguard and re-attaching the barrel guide. Im looking at a 10.5 inch barrel.

There's really no point in going to all the work of modifying the handguard so that the plastic cap fits in after you shorten the barrel. It doesn't contact the barrel and just keeps small children from falling in.

A friend told me he once had a dream of a M&P 15/22P top receiver falling on a rifle lower. He said the dream was quite nice.
But that's just hearsay!!!

Dangerous ground left best un-tread.

I posed the same question quite a while back. The possible, perhaps un-likely un-intended consequences scared me.

I'm imagining a 15-22 with a 6" barrel and thinking that it would look too short.

Love mine, factory cut to 6" and about 2k rounds thru it with no problems.

Awesome, looks great! What rail covers are those and how about the little nub piece on the bottom rail? where did you get that?

Nice!

I'm only guessing, but it appears to be a chopped Magpul AFG.

Looks like a Gear Sector to me.

Good stuff; I have a couple of GS bits on order...

Those are the Troy rail covers and GearSector hand stop. GS makes awesom stuff and Jason Trusty is one hell of a guy to deal with, lifetime customer here.

Low Down, your SBR looks great with the suppressor. Without the suppressor, the barrel is silly short. Is your GS hand stop on backwards? It looks like it would be a lot more flesh friendly with the radius towards your hand.

It can go either way, I just found this to be more comfortable then the other way.

Low Down,
A question for you. I have both the M&P15-22 and 15-22P. I am currently waiting on the paperwork to arrive for my suppressor. I plan to swap the suppressor back and forth between the two M&P's and a Sig Pistol. For the M&P pistol I have acquired a rifle handguard and am going to be trimming it down a bit and swapping it for the super shorty one. It's going to end up exactly like what you have already done, but still in the pistol platform.
So to the question in all this....How do you secure the barrel when you re-torqued the barrel nut? Once it's down inside the new longer handguard there is nothing left exposed to clamp in the vice jaws.

I've always just used the upper receiver. The barrels isn't tight like it is on a regular AR. Should I do it this way? Probably not but I haven't ever had issues with doing it this way.

Awesome, I have a Gearsector sling and its quality, off I go to spend some money!

Low Down

I'm waiting on my stamp now who did the marking of your receiver?

My local gunsmith. He's 10 min away from house. I have him thread and crown all my barrels. Former marine and long range shooter.

Thanks.

How and where was it marked?

My current SBR is marked on the front of the Magwell but it is aluminum.

What do you mean how? It meets all ATF requirements. I had mine marked on the right side of the magwell. I wanted it under the trigger but he wouldn't do it there. I'm sending my current SBR build off to Ident to be done under the trigger.

First the question. With your barrel cut to 6" do you still have to use subsonic ammo or can you use reg bulk ammo and stay subsonic? EDIT- Duh it would be the same as my can on my pistol and would need subsonic ammo.

Secondly a big thanks for your info. This just answered about 10 questions for me in regards to barrel reinstallation.

I own the 15-22 rifle and 15-22 pistol but always wanted a internally suppressed 15-22 sbr. The pistol has rarley been used and just never had a "fit" with me like I thought it would. I also own a YHM suppressor 22 that I really like.

I plan to take my pistol and cut the barrel down to 3.5 to 4 in and re thread and re install using a longer hand guard that I will cutdown to desired length. Then my YHM suppressor will thread onto newly cut barrel and down into the hand guard and stick out approx 2 inches or so (or what ever looks correct). Total length with barrel and suppressor will be right around 9-10 inches.

Then after sbr paperwork comes back, engrave reciever and add buttstock adaptor and buttstock. Turning the pistol into a internally looking supressed sbr.

My thoughts on this:
-Cutting the barrel down to 4 in will allow bulk ammo to stay subsonic.
-It still allows me to use the suppressor on multiple hosts.
-Turns something I currently dont care much for into a bad ace toy.
-Since I have most of the big ticket items cost is not a issue.

Only negative on this is this platform would always need to have the supressor installed to use. But I honestly dont think it will come off much once I have it set up this way. And the short barrel will effect accuracy.

I have two Ruger pistols, 4.5'' and 5.5" barrels. Typical bulk HV ammo stays subsonic with 4.5" but not with the 5.5". That said, I can buy CCI Standard Velocity at Dick's Sporting Goods for $25/500 which isn't that much of a premium to pay over HV bulk, and CCI SV stays subsonic in 16''+ length barrels.

Even at a 6" barrel, I can still hit 2" spinner targets offhand at 50 yards with a red dot. I'm almost tempted to do another now, its just way too much fun.
