AR pistol project

biggie24420 · Dec 8, 2013

So I decided to build my second AR "platform" firearm. My fist was a rifle and now I am interested in building a pistol version. I don't wanna go through and pay for a SBR, so I have decided to go with a pistol instead. That way if needed, I can conceal carry it, I don't have to worry about anything when/if I travel... unless I am going to a restricted state. It will just be a nice PDW/pistol for range use..... maybe home defense if needed. Depending on how things go, I might get the SB15 also.

I just built my first AR pistol too, 10.5" as well. The SB15 is awesome by the way :winkkiss:

Here's my question to those who have used the SB-15: how often do you actually strap it to your wrist? Conversely, how often does it "accidentally" rest against your shoulder? I ask because I strapped one on at a gun show and it seemed awkward if you try and hold the gun normally.

Just needs buffer spring, buffer, upper, and sights.

If it's a pistol, you should pick up an SIG SB15 brace for it.

For...you know...one handed use...

the reason may be because of the angle of an OEM PG.
The Umbrella Corp PG is much more vertical (for AR pistols) so that you get better farfenugen!

biggie24420 · Dec 21, 2013

Yeah... depending how it goes, I might get the Magpul MOE K2. I like the Umbrella Corp one, but I think the K2 will fit my large hands better.

As far as the SB15 goes, If I can get away and be comfi with my current setup, I'll keep it. I can shoulder the lower pretty good, and once I have my body armor on, I think I can get away with not getting the SB15........ but I'm leaving that option open for the future.

I am also building something similer. I am looking for the legality of the different options on either a short barrel rifle or the pistol route with that Sig brace. I was told by a dealer and I dont know if its true or not but he said I can put a pistol upper on a rifle lower and it makes a short barrel rifle. Anyone know if that is true? Also if a short barrel rifle is legal can I put a broomstick on it as well?
Any help will be usefull.

A short barrel rifle is definitely not legal without a tax stamp.

To legally build a pistol you must assemble it from a lower that was never built as a rifle. Once first built as a pistol, you can convert it to a rifle (barrel over 16") and back to a pistol.
