AR Pistols
« on: November 07, 2013, 01:12:30 PM »
Anyone own or built an AR pistol? I'm building one up for my wife in 300 AAC. 7 inch barrel, EoTech sight with 45 degree backup iron sights. She loves both of our AR rifles (but thinks they are heavy) so I am building her an AR pistol. The cool thing is she is so small she can shoulder the AR pistol like a rifle so it should work out well. Currently waiting on parts. It would be nice to give as a Christmas present.  :P

7" barrel 223? I'd go at last 15" for a little accuracy and a little less bang. Unless your local state law forbids, of course.

I've not built any AR but have thought about it. How much are lowers going for?

7 inch 300 Blackout.  :thumbsup:

Lowers seem to go from $90 and up.

Keep an eye on primaryarms.com, they seem to be running specials on the regular and with black Friday / Thanksgiving / Christmas coming up they'll definitely be running some deals.

I got an Aero Precision stripped lower from them on sale for $69 not too long ago.  (Not including shipping and don't forget your local FFL's transfer charge).

They currently have Aero Precision forged lowers for $90.  https://www.primaryarms.com/Lowers-s/3930.htm

We don't really do AR pistols up here as there's no significant barrel length rules to ARs.

But one thing that strikes me as a little odd is the Eotech + 45 offsets.  Why not just run regular sights?

I like 45s on guns with magnified scopes but with red dots, I just look through the glass.

More than likely it will end up with just iron sights. I want to see how the above setup works. You right, they co-witness on my other ARs and its not a problem to use either.

I was at a gun show last weekend and looking at a few AR pistols. I'd love to build one and add that Sig Sauer SB15 arm brace. Not to use it as intended, but as a butt stock.

It seems like it would work well after trying it on a couple of pistols at the gun show and is ATF approved. You could have a fun little SBR without the tax stamp and its completely legal.

Yeap. Thats plan A then after I move to a free state I will pay the tax for the SBR and a suppressor.   ;)  Still on the wall with the barrel length. 7 or 9....I want to go 7.  :D

But the performance out of a 9 inch barrel is tempting.

Barrel                                     Cartridge                                     Velocity                       Energy
9 in (230 mm) barrel    300 AAC Blackout, 115 gr UMC    2,120 ft/s (650 m/s)    1,136 ft·lbf (1,540 J)
16 in (410 mm) barrel    300 AAC Blackout, 115 gr UMC    2,295 ft/s (700 m/s)    1,344 ft·lbf (1,822 J)
9 in (230 mm) barrel    300 AAC Blackout, 125 gr OTM    2,030 ft/s (620 m/s)    1,143 ft·lbf (1,550 J)
16 in (410 mm) barrel    300 AAC Blackout, 125 gr OTM    2,215 ft/s (675 m/s)    1,360 ft·lbf (1,840 J)

I don't worry so much about paying the tax stamp, its the waiting period. Now that people seem to be figuring out you can  buy suppressors and short barrels it seems the wait times are getting longer. One local gun shop told me its at least one year wait to process the paperwork.

That's a long time to wait for your toys!!  lol

Curious to hear how the 300 BO works for you.

Making a pistol for sure and thinking about making a rifle as well. Probably a 16"er, I like what I am seeing ballistic wise from some of this load data. For such a small case you can move a 115 - 150 grain bullet right along.  Then there is the subsonic thumpers.  :bigsmile:

Changed course, went ahead and made a 9mm AR pistol and will be making a 300 blackout rifle with a 14 inch barrel next. Pics at noon. OK maybe this weekend.

Now to head to the desert to test function. I have been thinking about buying a big outdoor trashcan and filling it with rubber chips. Cutting a small hole in the lid for the barrel so I can test fire actions in the garage.

That thing needs a Sig brace yesterday.
A plan is just a list of things that doesn't happen.

And it fits my wife perfectly. She likes it.  :bigok:  I may end up replacing the plastic 80% lower with one of these. It uses Glock magazines and the reliability is supposed to be spectacular. Not that I have had any issues with my setup but I like the fact that its machined to use the Glock magazines.
