Product description
Large Capacity and Compatibility With Mil-Spec Lowers
The CMMG 32-Round 5.7×28 Conversion Magazine is purpose-built to feed your 5.7x28mm AR-15 with reliability and ease. Whether you’re running a CMMG 5.7 upper or a full Mk57 pistol, this magazine is what you need. Designed to fit mil-spec AR-15 magwells, the conversion mag allows you to run 5.7×28 without any proprietary lower receiver. With a 32-round capacity, it gives you plenty of rounds in a lightweight polymer body. From the new stylized texture grip and “5.7x28mm” engraving on the sides to the upgraded feed lips, these magazines are built to exceed your expectations.
