So? I was about to get a full size rifle, but I like compact sized. And being a WC and a reputation for barrel quality. And being 2k and I'm getting it for XXXX ;). I just can't resist. An AR pistol is what I really wanted anyhow. The stock folds and is adjustable. Very short. Will be a perfect match for the suppressor I have picked out.
:)

Yeah, the way things are going.

I would say the recent ATF decisions impacted the price a lot as they may be illegal very soon with the brace. I would personally get it and send in the paperwork to register it as an SBR to be safe and allow to install a butt stock.
That would be the right move probably.

Yeah, I'll register as an SBR and I plan on a suppressor also. Main reason for wanting so short.

For use with a suppressor I would suggest 300 blackout personally. Especially with the short barrel. 556 doesn’t suppress very well. Also when you goto buy a can dont buy a 556/223 can buy a 300/308 can the difference in sound is negligible and can be used on more calibers this gives you far more versatility. Same goes for pistol cans IMO if buying a pistol can get it in 45.

11.5” is the best barrel length for pistol/SBR, it’s suppresses just fine
You did good.
WWB can correct me if I’m wrong but I don’t think he meant you can’t suppress an AR pistol, yeah shoot supersonic bullets all day with your suppressor. if that’s your thing.

However, 5.56 is a tricky round to slow to subsonic velocity and reliably function suppressed.....in a short barreled rifle.

At the point of loading 556 down to subsonic you have essentially made 22LR why not just use 22LR for pennies in the dollar? The point of my post was that 300 blackout performs much better out of a short barrel then 556 does. It is also very quiet with off the shelf subsonic Ammo. And at subsonic velocities will have a lot more energy then a 556 at subsonic speeds. If you shoot supersonic regular 556 your suppressor will make it quieter but still not hearing safe and will ring your ears still and imo not a lot of fun cause they gas back in your face a lot more then 300 does. This can be remedied to a point but it’s still louder then a 22LR without a can. 300 subs sound more like a pellet gun. 556 performs best out of a 20+ inch barrel 300 performs much better out of shorter barrels. Under 14” your better off with a 300 IMO regardless if using a can or not it’s just the better round for short barrels any way you slice it. The good news is if you want you can swap out just the barrel on any AR and shoot 300 blackout all the rest of the parts are the same as a 556.
if you don’t mind it being obnoxiously loud at the range without the can and the decrease performance of 556 from the short barrel the 556 is/was cheaper to shoot if you just want it as a high volume range toy. That is basically the only thing 556 has on a one up on 300 in an sbr. IMO
I have a 556 and 300 sbr and a can for then so I’ve done this before and can tell you the difference in sound suppressed isn’t even close..

short barrel 5.56 is very effective imo, enter the mk18, or 10.4” hk416
honestly a subsonic .300 blk is more of a range toy to me than a loud SBR 5.56.
Shooting super sonic 77gr 5.56 in a 11.5” vs sub 300 blk I don’t think there is any comparison for effectiveness,

If you own these guns you should agree, a 300 blk even with sub sonic is not hearing safe,
just like a .5.56 suppressed is not hearing safe

300 is half or less loud then a 556 shooting subs. If you shoot super to super the 556 doesn’t have more energy. The 300 does. When your talking subs to supers obviously the 556 does have more energy but it’s twice as loud. This is all talking about under an 11” barrel both calibers.
The point of a suppressor imo is to be quiet as possible otherwise what’s the point? Is 300 hearing safe through a can technically no but it’s doesn’t ring your ears like 556 still does.

300 blk subs range 120-124 db, 5.56 super - 134-138 db at the muzzle
Not sure what you mean by half as loud or twice as loud :)
but agreed it does have less bite. With a bolt action 300 shooting subs, it would really shine


Don’t get me wrong, 300 is a great cartridge, a 7.5” bbl, .300, 110 gr has roughly the same energy as a 11.5” 5.56 shooting 55’s. So I bought a 300 for being compact and having about the same power as a 5.56 despite a much shorter barrel. I shoot both...but as OP has an 11.5” 5.56x already coming, I don’t think you are missing much with a 300 blk. Anyway just my .02

And seriously buy this gas block - https://shopwilsoncombat.com/Wilson-Combat-Bullet-Proof-Adjustable-Lo-Profile-Gas-Block-750-Carbine-Length-Straight-Gas-Tube/productinfo/TR-AGB750-C/

WWB what’s your opinion on potential impact of “Others” for us CT folks that aren’t LE or military? Wondering if it’s even worth buying any more of them at this point. Thank you

To the ear it’s twice as loud IMO you don’t have the supersonic crack which is where all the extra sounds comes from. The sound travels much further down range also with the Sonic boom. We Can argue Symantec’s all day but 300 is a better short barrel round and suppressor round end of the day. I’ve used several adjustable gas blocks as well mixed results. For SBR 556 piston gun is my choice. Lwrc or PWS

I've backed off getting the WC AR pistol.
I still however want a short AR. Either as a pistol or SBR. I'm thinking of a 300 now in a pistol. Then get the stamp and register as a SBR. Then add a suppressor later.

Well can't disagree with you guys on the db registered, that was my mistake to phrase it that way.
The pop you get in your right ear off the ejection port is what I am trying to refer too;
which is the most noticeable when firing.

A 7.5" 300 blk with subsonics and a 5.56 11.5" with supers are about the same noise level to me on the shooting ear. I shoot both of these often. Not very scientific, but my perception. See below when it says average @ shooters ear.

I only bring it up since many, including me, will think 300 blk will be "whisper quiet" with subs.
