ProMag 50rd 9mm Glock-Style AR-15 Drum Magazine

The ProMag 50-round drum magazine is designed for 9mm AR-15 carbines that accept Glock-style magazines. The drum housing is built from a DuPont Zytel-based polymer to keep weight reasonable while providing a durable exterior. The magazine upper tower includes a full-length steel internal insert for reliable feed geometry and a flush-fit design for Glock-pattern magazine wells. This magazine is made in the U.S.A. and intended for use in platforms that accept Glock-style 9mm magazines; it is not designed for direct use in Glock pistols.
