The GrovTec Limited Rotation Push Button Swivel Base replaces the swivel looop on the M16/AR15 Rifle and M4 Carbine. It also works with the M14/M1A, and M1 Garand; however, the base that goes into the stock is not as wide and leaves a small gap on either side, but it is perfectly functional. The rear push button base features limited rotation of the push button swivel to prevent the sling from twisting.
