M203 is a Colt 40mm DD with a 9" LMT barrel. Barrel is a 12.5" Daniel Defense gov profile with a Black River Tactical .0635 insert since the factory port is .073. Muzzle device is a KAC NT4 that will host a taupe NT4 suppressor once it clears. Upper is a Colt Cerro with a stamped C with a PRI gas buster CH and Colt BCG. Lower is a SBR'd 2018 "Property of US Government" marked Colt M4A1 with a CQD mount, Colt H2, B5 gen 1 contract overrun on 4 pos tube, custom polished stock Colt trigger group, 4lb hammer spring from MCarbo, and a shaved A2 grip with some electrical tape for grip. On the rail is a full power PEQ-15, NAVSEA marked rotation WMX200, Insight dual switch, KAC irons with a large knob 2-600m rear. Optic is a gen 2 SU230 marked Elcan 1-4x with a ARMS 2 mount and a 7MOA Docter on top. Waiting for my transferable M16A1 lower to clear to use with this build as well. I'll be putting the VLTOR A5 buffer system with a Geissele SSF on that.
