This is the complete upper assembly from our re-imagined A1 Government rifle – it includes classic features, but it’s built to shoot. This assembly starts with a 20″ A2 profile barrel machined from 4150 Chrome Moly Vanadium steel with a chrome-lined bore and chamber. It is rifled with a 1 x 7” right hand twist and includes an A1 flash suppressor. A rifle-length triangular handguard with A1 delta ring complete the assembly. The machined 7075T6 aluminum A1 upper receiver includes a brass deflector, ejection port cover assembly and  a teardrop forward assist.   This option does not include bolt carrier and charging handle.
