Surefire 60 Round AR-15 Magazine 223/5.56 are compatible with M4/M16/AR-15 variants and other firearms that accept STANAG 4179 magazines. These 60 round magazines feed smoothly and reliably due to optimal geometry, non-binding coil springs, and nesting polymer followers. The long-lasting springs are cadmium coated for low friction and excellent corrosion resistance. Magazines require no lubricants and can be easily disassembled without tools for cleaning. This magazine also gives you the benefit of being skinnier than using a dual magazine coupler and no reloading.
