CMMG AR Conversion Magazine MK4 /AR15 5.7x28mm FN 32rd

The CMMG AR Conversion Magazine MK4 /AR15 5.7x28mm FN 32rd provides a reliable feeding solution for operators transitioning their standard AR-15 lower receivers to the high-velocity 5.7x28mm caliber. This magazine allows users to maintain their existing muscle memory and control configurations while benefiting from the unique ballistics of the 5.7mm cartridge.

With a capacity of 32 rounds, this magazine is engineered to ensure reliable feeding, addressing a common failure point in firearm systems. Its precise internal geometry is designed to handle the bottlenecked 5.7x28mm FN casing effectively. The magazine fits standard AR-15 mag wells and requires only a compatible 5.7x28mm upper receiver for complete functionality.

This magazine is an excellent choice for shooters who may be sensitive to recoil or those operating in confined spaces where maneuverability is crucial. The reduction in weight and recoil offered by the 5.7x28mm round enhances the shooting experience, making it suitable for both high-volume training and specialized defensive scenarios.
