The Next Chapter reviews the AR-7
IMHO, this is an affordable, expendable rifle. When weight and size are critical for packing, it is something that I can carry for use as a last resort, something that may be just barely enough gun to do get me through an unexpected crisis. It will never be my first choice for a kit gun or a survival rifle; it is an alternative.
While it will never be as popular as the versatile Ruger 10/22, the AR-7 does have a following. Only you can decide what would be a good fit for your kit.
