GRIFFIN AR15 STOCK MOUNTING KIT

This package includes the Griffin AR-SOB buffer (Gen 2), Griffin AR15 7075-T6 Maritime Receiver Extension, 17-7 wire spring, QD Contour Connect End Plate, and castle nut. All these parts will complete the back end of your lower receiver.

This kit is applicable to Ar15 family firearms and is compatible with Mil-Spec dimensioned butt-stocks.

Note: Griffin uses 17-4 Stainless Steel as material for our castle nuts. This is an incredibly strong alloy, but should not be staked because it has the tendency to crack rather than dent like other alloys. We recommend using a thread sealant such as ST-3 to hold these castle nuts in place. We sell this in small quantities here.
