Found a box of discontinued StockGloves! The StockGlove was an original design from ITC when I first started the CheekRest/RailRest products. Designed for the M4 style telescoping stock like the old style Bushmaster carbines, M4A1's and AR15 to name a few. (See images below). They sold well back in the day, but the butt stock designes kept changing so I retired the product.
The StockGlove is designed to elevate the comb for the telescoping stock. Slips over the entire back end and is laced up to insure stability and function. Includes top and side sling ports, non-slip rubber underside, 3 foam pads and internal pouch. Butt plate area is made from a non-skid material to help eliminate slippage off the shoulder while operating.
