Sig Sauer MPX Copperhead 9mm.

The Sig Sauer MPX Copperhead is a 9mm PCC that has redefined the sub-gun category. Finished in black, it features a 4.5-inch barrel, an MLOK handguard, a muzzle brake, top and rear mounted picatinny rails, a Timney single stage flat faced trigger, and one 20-round magazine. 

The Sig Sauer MPX Copperhead features a monolithic Elite Series Cerakote finish upper receiver, with an integrated stock knuckle lower, and a 4.5 barrel with integrated muzzle brake. The Sig MPX Copperhead operates from a fully-closed and locked rotating bolt, offering enhanced reliability and safety in use.
