We bought a used Armalite AR-7 Explorer rifle from a recent antique gun show. This is a breakdown style gun that comes apart in pieces and is stored handily inside the stock, supposedly waterproof and able to float making it ideal for backpackers.
The design concept is fantastic, but It’s performance was MEH. Other manufacturers improved on the design in later years which would make it more useful than novelty. In any case, it’s still a neat gun to have in the collection.
Here’s the quick video we put together demonstrating our first time out with it, using three different types of ammunition. It jammed with all but the most expensive of the ammo. I wouldn’t want to rely on it in a life or death situation.
