ProMag AR-15 5.56 120rd Drum Magazine

A 120 round drum magazine for AR-15 rifles in 5.56mm and 223. It is made for range days when you would rather keep shooting than stop and reload a stack of stick magazines.

The body is a Zytel based polymer with stamped steel feed lips and a steel magazine catch over molded into it. An injection molded follower and a spring of heat treated chrome silicon wire move the rounds up. Use it for long plinking sessions and high volume range work.
