Angstadt Arms 0940 9mm

A little slow motion of my compensated UDP-9 pistol. I am consistently holding 3" groups off my cheek at 25 yards.

This is the same sequence in real time.

Did you build it or buy the complete pistol? Looks like fun.

I bought it as a complete pistol from Angstadt. I added the glass, laser, Elf Trigger and compensater. After some testing, I think I like the LanTac USA DGN9MMB 9mm Dragon best so far.

Here is a pic on the gun.

Here is the typical sort of accuracy I am getting off my cheek at about 3 sec per round.

I took the A5 off and replaced it with a standard mil spec Voltor RE. The Spikes ST9 and a Wolf extra power carbine length spring. It ate a 17 round mag with no issues.

Good write up. This is my first post on the forum, but long time shooter. Im building an ar9 with the AA receiver set, and their bcg. Just waiting on my buffer and i can give her a test run.

Rich from AA was great answering my emails, and their parts are very high quality.

Welcome Aboard. This is a great forum. I agree Rich is outstanding! I'm looking for a barrel now to build up on the AA upper. I want something short. In the 4" to 5" range. I'm trying to decide on a 7" or 8" BCM KMR rail. A 3 lug TROS HBO is in the running but I will probably get a bit with 1/2x28 threads so I can out a fake can on it until I get a 9mm suppressor. I did that with a short .22 build. I would like to get a 9mm suppressor and SBR the lower. I wish I had a money tree in the back yard.

I want one of these too:

Thanks. Sounds like you have a nice build planned. Unfortunately for me, i live in the peoples republic of new yorkistan. So im pretty limited legally.

I'm going to order a Hahn mag block to use in one of my SBR's while I wait for paperwork on this lower. I have some Colt magazines on my he way.

I have a TROS bbl inbound and a 7" BCM KMR. I will need a FH to make up the difference to the end of the rail. I just confirmed the 5" TROS will extend about 4" forward of the barrel nut.

Help me decide. This is what I was thinking its 3.3"

These are options too.

Very cool but almost 14 ounces!

From the barrel nut threads forward to the muzzle is 4.0".
