Specifically designed for reliable service in tough, rugged environments, the Henry® US Survival AR-7 Semi-Auto Rimfire Rifle has been carried by bush pilots and backpackers for decades. The AR-7 quickly and easily breaks down to store inside the floating buttstock to stow in the trunk of a vehicle, in a duffle bag, or anywhere one might need a .22LR rifle in an emergency. In a few seconds, without the use of tools, you can assemble the rifle by attaching the receiver to the stock, inserting the barrel, and hand screwing a threaded ring, which is permanently attached to the barrel, until the barrel is tightly fitted. The receiver is made of alloy, and the rifled steel barrel features an ABS plastic coating for superior corrosion resistance. A rear aperture sight and a blaze orange front sight blade are rugged and reliable, and allow precise shot placement. The AR-7 Semi-Auto Rimfire Rifle uses an 8-round magazine (comes with 2) for fast reloading.
