The AR.5 is a bottle opener designed to look like a miniature AR-15 lower receiver, manufactured by Arizona-based Nelson Precision Manufacturing. Machined from 6061 aluminum and Type III hard coated black anodized, the AR.5 Bottle Opener is detailed very much like an actual lower receiver, with the trigger guard pin extensions functioning as the bottle opening tool. Plus, if the product images are anything to go by, each bottle opener is individually serialized, which is pretty neat.
