Ghost Firearms 9mm Adapter Drop In Mag Block

This Adapter Drop In Mag Block converts your standard AR-15 model to accept affordable, lower-penetrating 9 mm rounds using a COLT STYLE MAGAZINE. Made from 6000 series billet aluminum with a steel insert for the feed ramp.

9MM Bolt Carrier Group

Complete, drop-in carrier/bolt assembly is ramped on the bottom to provide clearance for a factory .223/5.56mm hammer in your 9mm conversion. Eliminates the need to install a dedicated 9mm hammer, so the original fire control system stays intact for easier conversion back to original caliber. Precision machined from high-grade ordnance steel, the one-piece design combines bolt and carrier as a single unit to provide outstanding strength, durability, and reliability. Includes a staked-on carrier key.
