The AR-7 was designed by Eugene Stoner for the US Airforce in 1958, a couple of years after he designed the AR-10 (which went on to evolve into the AR-15). This Henry AR-7 Survival Rifle, I am sure, would have put a smile on Stoner’s face.
“bronco” developed a conversion kit which allows a standard AR-15 pistol grip and stock to be attached to the AR-7 receiver. A forum posting over at the Predator Wild forum seems to suggest he may be willing to sell these kits.
Next Chapter has written a review of the Henry AR-7.
Many thanks to Heath for sending me the link.
