ProMag Colt AR-15 223 Rem / 5.56 NATO 20-Round Steel/Polymer Magazine Black

Pro Mag Industries AR-15 Magazine Features The ProMag AR-15 Magazine uses a hybrid design that pairs a heat treated steel upper with a DuPont Zytel based polymer lower housing combining the strength of steel where it matters most with the reduced weight of polymer elsewhere. The steel upper carries a black oxide finish that resists corrosion and wear from repeated loading and unloading. An injection molded magazine follower helps ensure smooth consistent feeding as rounds are stripped from the magazine during firing. This combination of materials is designed to hold up to the demands of range use training and duty carry alike. Inside the magazine a spring formed from heat treated chrome silicon wire maintains reliable feeding pressure over an extended service life without losing tension. Built to fit AR-15 M16 and compatible .223 Remington and 5.56x45mm rifles and carbines this magazine drops into the vast majority of AR platform firearms without modification. Made in the USA the magazine offers shooters a dependable American made option at an accessible price point compared to some competing designs. With a 20 round capacity this ProMag magazine is a solid choice for range sessions training drills or as a spare magazine for any AR-15 pattern rifle.
