Some of the parts I've had just sitting in the safe awhile, so I ordered up the rest and put this together.

Ballistic Advantage upper & lower
Ballistic Advantage 12.5" barrel, 308
Superlative adjustable gas block
Aero Precision Atlas R-One 12.7"
Aero Precision bcg
Armaspec Stealth recoil spring
Radian Rapter SD charging handle
Radian safety
Geissele SSA-E trigger
Vortex Viper PST2 1-6 MRAD in a Reptilia mount
Rex Silentium MG7 308, Xeno mount & flash hider

I haven't had a chance to sight it in yet, but I have shot it to get the Superlative gas block dialed in. Gonna get out next weekend to sight it in.

I like it!  I’m curious what the velocity loss/ammo considerations look like. I’m thinking about how the 5.56 selection narrows considerably with shorter barrels, but I know that 556 is more sensitive to velocity as to whether it performs as desired.

Will you sbr it?

Eventually... we'll see after I get more time behind the trigger.

12.5" 308 is awesome. I always love a chance to trot out pics of my POF Rogue 308 sbr.

Very similar 308, except being in NJ I can't SBR it or own a suppressor. Has to remain a Non-NFA Other.

been thinking about something like this...please let us know how that barrel is both accuracy and gas.  I avoided BA barrels (went criterion) due to reading about the gas port size being too small.

Thanks, looks nice!

I already have a 16” rifle length gas ar10 but I’d be lying if I said I didn’t want to build a 12.5” for some reason.. They just look good lol.

I hope that BA barrel is a shooter.
