Home Forums Hunting & Shooting AR and Tactical Rifles AR Pistols

I've been researching AR pistols. I love the operation platform of the AR. But im not sure the .556 is the best cartridge to fuel it with in my situation. In my perfect world I could build a .40 S&W on a AR frame with a 10" barrel and it wouldn't be classified as a SBR.

IMO, the AR platform is a poor choice for a pistol. Especially when you consider pistol calibers. They are popular because people can put a short barrel on an AR and avoid going the NFA route (or have a pistol receiver for their SBR when traveling to and from shooting). They are becoming even more popular now with the sig arm brace. A suppressed SBR would be fun and somewhat practical. I just can't think of a void I have that a AR pistol would fit.

I have not seen many pistols in that format.

Especially in a pistol caliber.

If I want a 40 smith, I'd buy a handgun. Not butcher an AR into a make believe bulky one.

I can see some uses, depending on ones job or future thoughts, of a pistol caliber carbine, but not a pistol off an AR for that.

I have fired a Colt 635(9mm SMG) and a 14.5" 5.56mm with pencil barrel AR carbine(same N type butts and basic external layout, only major difference was caliber and internals to get there) I perceived more muzzle flip from the 9mm version than the 5.56(obviously nothing major from either, but more from the 9mm never the less), although the 5.56 was much louder.

9mm is also supposed to be somewhat harder on certain AR parts than 5.56 guns. Colt 9mm hammer pins are stainless instead of using their standard pin from the 5.56 guns as an example. I would assume any of those traits could be enhanced by way of the .40(although Olympic Arms uppers are typically described as "plug & play") but may be some points want to research while making your decision.

The Sig brace allows you to skip the $200 tax on the SBR lower and still have a six-inch barrel and a can. 9mm 147gr XTP's out of such a rig would make the ULTIMATE house/car gun

I was never overly impressed with an AR pistol i always figured they were just noise makers, and have no real purpose.

That changed yesterday. I was at our local range and there was 5 guys and a bunch of AR type rifles and pistols. Those guys were ringing 2 yard steel with 10 inch barreled AR pistols. I had to give them props.

I wouldn't mond having one with a 10-12 inch barrel and one of those Sig arm braces

I used to think they were silly before I had a chance to use on on a Roger's Range. Stages that I struggled to hit 75% of the plates were easily cleaned with the pistol carbine. Four points of contact make like a LOT simpler.

AR 'pistols' are a joke, and nothing more.

In my state (Alabama) one can hunt turkey with any centerfire mushrooming ammo from a pistol. Now, and AR pistol shooting a 223 can knock out a turkey at 100 yards. Can't do that with a shotgun.

I bet They probably wouldn't make a bad house gun if they were set up properly

40 carbines have a history of sucking major ass.

Yeah, but where is the fun/challenge in that?

If you're replying to me, I wasn't thinking a .40 carbine. I was thinking 5.56 in a handgun, specifically with that sig arm brace on it

No. Just stating in general that the .40 carbines have had lots of trouble.

I know RR is making one now, but I have no idea if it's worry free or not.

Either way, make my AR anything a 5.56.



Travis

Gotcha. Yea i'm typically a 5.56 guy. A buddy has one in 6.8 that he built that is lots of fun, but no practical use to
Me. A .40 carbine of any flavor does'n interests me, but to each there own

I spent a lot of time with an 11.5" 5.56 SBR and wouldn't want to again without a can.

With a can I'd do an 11.5" house gun as an SBR or with the Sig brace.

Yea, the can would definitey be a neccesity

I've shot a sig AR pistol in.556. They're to loud and the muzzle flash in 7 inch will sunburn you in 30 rounds. Looking for an alternative.

9mm or.30 blackout seems to be it. An AR pistol properly accessorized (EO Tech & a light) in the right cal. 556 isn't it for my application. I have a halo site mounted on a ruger 44 carbine and its a deer killing machine.

Looking for the 100 yard PDW.

Thanks for the opinions.
