Been wanting to do a pistol lower for a while and also built up this upper late last year to scratch the carry handle itch. The setup is insanely light compared to my rifles with rails/optics/etc. This ones coming camping.

Specs:
Brownells/Nodak “C7” upper
Toolcraft Nitride BCG
Colt 10.3” barrel assembly w/ A2 FH
Aero lower and lpk with an LMT trigger I had
SBM4 Brace
