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″
