Designed to Work in Your Pistol-Caliber Carbine

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 FM Products AR-15 FM-9 Bolt Carrier Assembly is modeled after similar Colt-style BCGs on the market in order to ensure consistent, reliable function.

Each FM 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.

  • Includes forward-assist serrations
  • Machined from forged steel
  • Made in the USA
  • Black finish

The FM Products AR-15 FM-9 Bolt Carrier Assembly is also ramped for use with both mil-spec GI hammers and 9mm pistol-caliber carbine hammers.
