The forged aluminum receivers feature a brown/tan finish, contrasting with the black handguard and small parts for a purposeful two-tone look.
The Geissele Automatics PN 05-284 free-float M-LOK handguard provides rigid accessory mounting and includes a continuous 12 o'clock Picatinny rail. A blast-forward/linear compensator is installed on the threaded barrel to direct gases downrange.
