BLAST FROM THE PAST: The Henry AR-7 .22LR Takedown Survival Rifle.
Designed in the early 1950s and released in 1958, Henry's .22LR AR-7 Survival Rifle was originally meant for USAF pilots as a compact collapsible survival and hunting weapon for if they must bail their planes and were stranded in the wilderness. The gun soon became popular as a general plinking and all-aound utility gun for the farm, camping, and the target range as well as small game and pest control and sales soared almost immediately after it's debut. The one feature that made the AR-7 stand out fron the rest is that the entire gun can be disassembled and all of it's components stored in the buttstock which is designed to float. At the present day, the new and improved AR-7 retails in all big box outdoor supply stores for around $280.00 and is built with a neoprene inner lining inside the buttstock to provide even more water resistance and comes with 2 8-round magazines that also fit inside the whole assembly.
NOTE: If you think the AR-7 by itself is a complete survival rifle kit, think again. In the Hatchet series of novels by Gary Paulsen, the protagonist Brian managed to retrive the crashed bush plane's AR-7 after fishing it out of the plane's submerged remains, only to find that the firing pin was broken and the rifle unusable, and him stranded hundreds of miles in the deep northern Canadian forests. It is advisable to keep some spare parts and springs for this rifle, and ANY gun that you are using as your primary EDC and defense in another small watertight plastic case like those used for storing toiletries for airline flyers and keep that handy too. Being unprepared KILLS.
