The TangoDown ARC™ magazine upper body features an advanced blend of N12 polymer. N12 exhibits superior strength & impact resistance when compared to common nylon 6 used in other commercial polymer magazines. It takes tough abuse in stride, with no cracked spines or feed lips…even when dropped loaded on hard surfaces or seated with excessive force. N12 maintains this tensile strength and impact edge in temperatures ranging from -30 to +140 F, proven in multiple independent test lab reports against other polymer and metal magazines.
N12 is also superior to nylon 6 as it’s dimensionally stable when exposed to moisture, meaning the magazine will not swell over time. Combined with the 2 piece/straight wall design, ARC™ magazines always fall free from the weapon with 100% reliability, guaranteed. Magazines can be fully loaded and store indefinitely with no feed lip spreading issues.
