Recently I've developed an itch for an AR Pistol with a Sig brace, effectively giving me a non-NFA weapon that's essentially an SBR. Anyone own one or have any thoughts on going that route?

Do you want to hit a target, or just make lots of noise?

Good zombie sidearm. I imagine they're a blast to shoot. If you've got the coin then go for it.

I've never shot a bullpup that didn't make me want to stay at the range all day

Why would an AR Pistol with good optics, a quality manufacturer and a shoulder brace be unable to hit targets?

Unless that was a rhetorical question, in which case hell yes I want to be able to hit targets.

That's no where near a shoulder brace. Holding a pistol that weighs that much will be hard to keep steady. The short barrel will result in a large amount of unburnt powder. That would decrease velocity and increase muzzle flash. If you've ever shot one, they're very loud with a large muzzle flash.

They're novelty firearms. Fun to shoot. If I had an extra lower receiver and money to burn, it would be a fun toy.

A bullpup design is slightly different. The barrel is closer to standard length, just the receiver is mounted farther back. Bullpups are usually fired from the shoulder, a much more stable platform.

I gotta admit, I’ve never been drawn to AR pistols. The guns have reliability issues, ear-splitting muzzle blast and so-so ballistic performance. And those are just the minor issues. The real deal-killer: accuracy. I can no more hit the target with an AR pistol than I can by throwing a piece of popcorn at the bullseye.

why would you take a rifle & screw up the accuracy by turning it into a weird pistol?

Plus it's attached to your arm so your clearing drills probably won't work right, no way to switch to off hand...

What, are you going to draw & stick your arm in a hole?

Just a novelty, about like a bump fire stock.

I have no information as far as accuracy is concerned but I do know that a .223 coming out of a sub-10" barrel is doing less than 2000fps. That greatly decreases its effectiveness. I would suggest 300BLK if you want it to stay accurate and effective.

I bet they are fun as shite though.

My boss has one but doesn't have the sig arm brace. He loves it and talks about it every couple of days. I haven't shot it but he said it's accurate. Obviously only at close ranges but it is a pistol. The sig arm brace is pretty awesome. It's basically just a way to get around not being able to have short barrels on a rifle. It's still very easy to fire from the shoulder and increases accuracy out of an AR pistol.
Bapple, why would you suggest a 300blk? My 110gr bullets only shoot 2,350fps. So coming out of a short barrel it would still be way slower than a 223. And if a 223 is under 2000fps out of a pistol barrel, I can only imagine how slow the 300blk would be. Not arguing, I'm curious.

Pat Rogers thinks they're viable

I also have a 11.5" with a sig brace, feels like shooting with any other stock I have ever used.

Yeah, for everyone thinking this would be fired as a pistol the Sig brace allows you to shoulder the weapon and fire it just like an SBR. An yes, it can be accurate. As for criticism regarding barrel length, I didn't say I was going to get a 7.5" barrel. Can you honestly tell me that there's a practical difference between a 10"/11.5" barrel on an AR Pistol and a 12" barrel attached on an SBR?

I'm not sure many of you know what I'm asking about.

Hickock45's thoughts

There are plenty of Youtube videos showing its effectiveness and accuracy.

SIG braces are the quickest and easiest way to identify homos. The cost for the brace is almost the same price to Form 1 it. Only a Form 1 let's you put a real stock on it that's stable and realistically useful. I also would one sbr a 300blk or a pistol caliber. 5.56 out of a sbr is akin to a bull with tits.

Previous post was mean and not necessary.

Do whatever makes you happy, but they are pieces of shite.

Hey, I was just coming here for information and advice, it's not like I said I was hellbent on going down this route.

No hard feelings, though.

novelty weapon. I built one and while it was fun to shoot, it was extremely loud and the muzzle flash was enormous. every time you shot you could feel the blast hitting you. I ended up selling it during the last AR frenzy.

I never shot it without hearing protection, but I would imagine it would be very painful if you did.

I've got a Sig SB15, .556. Eotech XPS2 and an angled foregrip. I've never taken the strap off the brace, and fires EXACTLY like a SBR from the shoulder.
It's a blast to shoot, and handles all the business it needs to from 100 yards, which is the farthest I'll ever shoot this little monster. I picked mine up from Lafayette shooters, and have ZERO regrets.

Look into Form 1 your lower. Efile has approvals coming back in under 30 days. About the same price, much more options. Also, the brace will be revoked before a sbr will be.

Velocity is only part of the muzzle energy equation, with the other being bullet mass. With most 300blk bullets being more than double the mass of a 5.56/.223, they have greater terminal ballistics at far less velocity. 300blk by design also needs a lot less barrel to get the most out of its powder charge, with less diminishing returns as you shorten the barrel. Here's a pretty cool graph demonstrating velocity vs barrel length. LINK

Exactly why I was looking into them, besides not having to wait for any NFA paperwork/approval.

I think the 300 BLK is supposed to actually burn all it's powder by 9"'.
