Description
The only thing better than a 100-round drum mag is a 120-round drum mag, and the ProMag AR-15 .223 / 5.56 120-Round Drum Magazine is the top choice for range day fun. This magazine is built using proprietary DuPont Zytel based polymer for superior strength and lightweight durability. The injection-molded polymer follower and chrome silicon wire spring mean consistent feeding shot after shot. Even better, this AR-15 drum mag has over-molded stamped steel feed lips and magazine catch to make sure cartridge alignment is consistent. Order now! Made in USA.
