The TNW Firearms Aero Survival Rifle (ASR) is engineered to breakdown efficiently without the use of tools. This unique configuration allows for easy barrel removal and caliber changes. The ASR's compact design allows it to fit in small storage compartments or its optional specially designed three day pack. This rifle is an essential piece of equipment for back-packing, boating, camping, back country flying, mountain biking, or hunting. The 9mm, 40cal and .45 all use Glock style magazines.
