The trick with survival rifles is to actually have them when it comes time to do some survivin' — and that's hard to do with an oversized killing machine. The Henry U.S. Survival AR-7 Rifle ($275) is a semi-automatic firearm that sports an 8-round .22 LR magazine, and features a unique design that allows the receiver and the barrel to fit inside the impact-resistant, waterproof stock, making it perfect for keeping at the ready in a bag with clothes and supplies, or for hiding at a designated spot in the wilderness for retrieval post-shit hitting the fan.
