BCM Bolt Carrier Group Completion Kit

Everything you need to finish your AR15 carrier into a complete bolt carrier group.  These parts are critical to the function of your AR and not a place to try and save a few bucks.  In our experience, BCM consistently provides quality parts that hold up to hard use.

• High quality components made by Bravo Company USA
• Includes: bolt, cam pin, firing pin, firing pin retaining pin
• Bolt assembly is machined from the correct Milspec Carpenter No. 158 steel, shot peened for increased strength, includes tool steel machined extractor, BCM Extractor Spring, and is HPT and MPI (Magnetic Partical Inspected).

Note: Our Ultralight Titanium Carrier comes with its own Titanium firing pin which should always be used with it.  If purchasing this kit, you will end up with a spare Steel firing pin which can be used for all other AR’s with Steel carriers (full mass or lightened steel).  This is a safety precaution to prevent slam fires.
