Originally meant for the Reising M50 SMG, these beauties will fit that .22 or shotgun in need of a sling. A ¾ inch threaded wood screw, permanently attached to a standard size sling loop (will fit Garand M16, etc. slings).
Used it to fit on to the wood stock of my Arsenal SLR-95 AK47. Not original equipment but you'd never know it. Looks great. Good price, too.
