Pistol Build 2017 .300BLK

I recently built an 8″ upper for my .300BLK SBR, but later decided I liked my standard 10.3″ upper on that one. Since I now had an extra upper assembly, I went out yesterday and bought an Aero Precision lower blank and built a new AR pistol with the spare parts I had and a Sig arm brace. Because I can. Can’t wait to try this one out this weekend!

  • Upper and lower receivers: Aero Precision (blanks)
  • Barrel: Ballistic Advantage 8″
  • Rail: ALG 8″

New SBR Upper

Today I assembled a new upper for my .300 BLK SBR. It currently has a 10.3″ barrel, but I wondered how it would run with an 8″ barrel. So I now have my 8″ upper:

  • Aero Precision upper receiver
  • Faxon Firearms 8″ hammer-forged barrel
  • BCM MOD1 muzzle brake
  • ALG 8″ handguard

I’ll put it through its paces on Saturday. We’ll see how she runs.

It’s possible that I won’t like it as well as the current upper/barrel, as I really like the way I’m setup now. But it’s possible I’ll really like the shorter barrel. We’ll have to see how it works for recoil impulse (for targeting), accuracy, and just how wieldy it is.
