Ok FINALLY finished the major mods on my ACR SBR Project:
-Front flip-BUIS removed and replaced with rail
-Shortened barrel to 10.5" with gasblock tucked into RIS
-Bushmaster ACR RIS
-PTS trademarks removed
-Upper receiver sprayed coyote brown (not a perfect match, but oh well!)
-Shell deflector sprayed black
Will be going with an AAC trilug soon and possibly a mock mock silencer option.
Comments appreciated.
