M1 Garand Web Sling Keeper Buckle M14 M1A M16 USGI Surplus - USEDUSGI M1 Sling Keeper Buckles. All available are original USGI surplus and good used condition, most all with little finish as pictured or need a good cleaning. Buckles can be used with cotton but not recommended for nylon since nylon is thinner than cotton web and hold will not be as good. These will work on most all GI Slings for the M1 Garand, M14, M1A, AR15, M16, and 1903. Several available so select quantity needed when ordering. Sold "AS IS" since old and used so all will be functional, just needing some cleaning and not prettiest compared to our newer offerings.
