You can have it for $20 picked up in Salem Sam - 503-507-5415 "The ultimate polymer magazine has arrived! A true 30-round capacity magazine for the 5.56x 45mm cartridge fits all M16/M4/AR-series/FN SCAR-Light/M-249 weapon systems*. Advanced design and construction allows for the strongest, most reliable combat magazine ever produced. Proprietary state-of-the-art polymers are combined to allow smooth, dependable feeding in a corrosion-proof unitized body. Oversized feed lips take constant abuse that would easily damage aluminum or steel magazines. Unique low-friction anti-tilt follower combined with a premium spring maintains reliable round delivery. Sealed modular design allows ideal straight-to-radius feed cavity, unavailable on any other polymer magazine. Additional benefit of modular design means no floor plate to fail upon impact. Magazine body becomes a five-sided box, setting a new standard for strength. Impact that crushes USGI magazines has no effect on the ARC. Magazine cleaning is a snap, requiring no disassembly thanks to the slotted follower. A soft seal joins against the weapon magazine well on insertion to prevent entry of dirt and other contaminants, a crucial bonus in desert warfare**. We designed in several features that make ARC user-friendly in harsh conditions. Large serrations on the front and back straps eliminate slippage when doing ‘push-pull’ magazine insertions. Deep ribbing on both sides enable a fast, sure grip when retrieving from mag pouches. An Open Water version is available, which features a self-sealing drain tab for OTB operations. · The ARC magazine is available in several color options, including translucent for visual round count. · The ARC magazine is manufactured using the latest in polymer Quality Control procedures, guaranteeing properly dimensioned components. · The ARC will drop free from weapon systems, regardless of origin, and will also seat easily in a bolt-forward weapon with a full 30 rounds."
