ProMag AR-15 .223 / 5.56 120-Round Drum Magazine

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.
