Magpul

While both the Gen 1 UBR and STR come with TYPE 1 push-button QD swivel sockets pre-installed on the left side of the stock, this Sling Mount Kit TYPE 2 can be installed on the opposite side to add additional push-button QD Sling Swivels or our own Magpul QDM. Additionally, for running ambidextrous sling swivels on the SGA, MOE Rifle, MOE Fixed Carbine, MOE AK, Zhukov-S, Hunter 700, and Hunter X-22 Stocks, this TYPE 2 Kit must be utilized in conjunction with the optional TYPE 1 Kit. NOTE: The Sling Mount Kit, TYPE 2 can NOT be used to run dual-side swivels on the ACS or ACS-L Stocks.
