In the corner, wearing a sailor outfit.
Robinson Arms XCR .223 Bought it from a guy in my unit who put a 18" heavy barrel in, CAA grip, VLTOR buttstock, different break, an upgraded trigger (not sure on the specs) and ACOG 4x with the RMR (CQ optic) Got a good deal on her, so I couldn't pass it up. Apparently this weapon was in the competition against the SCAR and ACR for a new battle rifle for the Army. But disqualified it because Robinson Arms didn't ship the BFA (Blank Firing Adapters) With them....Which Robinson Arms said it was Fedex's fault. But anyway, it's piston driven and has similar internals to the 249 SAW. The safety rotates 60degrees instead of 90 degrees.
