One of the essential components of an AR-style pistol-caliber carbine is the use of a purpose-built bolt that can accommodate the unique internal setup of these blowback firearms. The Foxtrot Mike Products AR-15 MIKE-9 Bolt Carrier Assembly is modeled after similar Colt-style BCGs on the market in order to ensure consistent, reliable function. Each Foxtrot Mike Bolt Carrier Assembly is machined from durable 8620H steel and finished with a salt-bath nitride treatment. The carrier ships with an M67 firing-pin retainer and uses a firing pin machined from 17-4 stainless steel.
The Foxtrot Mike Products AR-15 MIKE-9 Bolt Carrier Assembly is also ramped for use with both mil-spec GI hammers and 9mm pistol-caliber carbine hammers.
