ASC Magazine for AR-15 Features The ASC Magazine is built from .020 gauge 410 series stainless steel alloy that is heat treated for added strength and durability. This stainless steel construction resists swelling in hot weather and cracking in cold conditions two failure points that commonly affect polymer magazines over time. Chrome silicon springs provide consistent spring tension across the life of the magazine helping maintain reliable feeding shot after shot. Enhanced anti-tilt polymer followers keep cartridges properly aligned as they feed reducing the chance of a malfunction during a string of fire. A 300 series stainless steel floor plate caps off the magazine body adding further corrosion resistance and durability at a high-wear point. Built specifically for the 6.8 SPC cartridge and sized for the AR-15 platform this magazine holds 25 rounds for extended range time between reloads. The magazine is completely manufactured in the USA from start to finish reflecting a commitment to quality control throughout the build. Finished in Flat Dark Earth the ASC Magazine is a durable reliable choice for 6.8 SPC AR-15 shooters looking to upgrade from polymer magazines.
