This is my first pistol build.
Here are the Current specs/ parts list:

Spikes Stripped lower
Griffin Armament A3 Pistol Grip
Anderson LPK (used a DPMS trigger that I had laying around, the Anderson looked rough and needs a trigger job)
BAD Enhanced Take-down and Pivot Pins
BAD AMBI Selector
Magpul Bad lever
KAK Receiver Extension, H2 Buffer, and Spring
Shockwave Pistol Brace
Spikes Tactical Enhanced QD Endplate

Aero Precision Upper
Radical Firearms 10.5" 300 BLK Barrel
Odin Works Low Profile Gas Block
9" UTG PRO Super Slim Free Float Keymod  
BCM Mod 3 Gunfighter Charging Handle
AIM Nickle Boron BCG
"300 AAC" Dust cover
BCM KAG
BCM Keymod Rail Panel Kit
UTG Handstop/ Barricade Rest
Elite Iron Bravo 1 Brake and Cover/ Blast Diverter

Optics are an older PA Microdot I had never used on a UTG rail riser (optic is currently at PA due to light selector being reversed 0=mid bright and 6= off)  
Magpul MS3 Gen 2 Sling

I have only shot supersonic through it yet.  It wouldnt go into battery with the standard buffer, so had to move to H2.  Worked like a charm after that.

two questions, wheres the can and why use the pigtail gas tube? other than that looks fun. im building a 8,5" bo pistol now. it will be my 6th ar pistol

Can is at my SOT waiting on the Form 4 to clear. and I ended up not using the pigtail.  It wasn't even close to fitting under the rail.  I sent it back.

Looks great

I like it, its sexy!!
