AR57 pistol first shoot

[bikemutt]

I finally got all the parts I needed together for my AR57 (5.7x28) and got it to the range today.

Have to say my instincts were right; it's a fun AR15 form-factor pistol, very low recoil, reliable, lightweight, suppressor-friendly and accurate. This one's a 6" threaded barrel. The threading is more than a typical .22 can likes to see (0.4") so I added a spacer nut to fix that. Also had my Huntertown Arms Guardian 22 upgraded to the Kestrel core so it's safe to fire semi-auto 5.7x28. The P-Mag has been gutted to serve as a brass collector since that's where the AR57 upper dumps it.

I can't really say how quiet it is since Friday afternoons are a zoo at the indoor range I shoot at, but through the hearing protection, I'm going with very quiet.

Figured I'd share a few pics.

Okay, that is freakin' cool!

But, um, why the 30rd mag?

Pretty pictures distracted you from reading the post completely.

Brass dump.

Awesome to the max, dude! I started thinking about such a platform when that ARES SCR lower concept was floated. Not a pistol, but talk about compact!

Here's my little Paint mockup

Yeah, I know it'd be a double-stamp unless you could somehow convince the ATF that thing's an arm brace


Hmmm, maybe you could cut the stock back enough the ATF wouldn't consider it an SBR, and have yourself a modern Mare's Leg? Just need ARES to sell some bare receivers...


Groups! How did she shoot?

I was focused more on operations (and safety being the first time with a new weapon component) than on groups. At 25 yards with the Primary Arms red dot I could keep everything in the black of an 8" NRA pistol target. I know it's better than that. Next time out I'll rest it to check inherent accuracy.

That thing is awesome thanks for sharing

Very nice!

Never would have thought about using the gutted Pmag as a brass catcher, would be handy if you go through all the trouble to reload 5.7x28mm.

I keep all the brass I can. When I buy fresh factory reloads locally they give me credit for any and all mixed brass by the pound. Not getting rich off it, still a hair bit better than a poke in the eye though

Needs a SIG SB-15 "arm brace"
