GRIFFIN A2 STOCK MOUNTING KIT

This package includes the heavy Griffin AR-SOB A2 length buffer, Griffin AR-10/”GA A2” 7075-T6 Maritime Receiver Extension, (Similar to industry A5 Length), corresponding AR-15 / M16A2 rifle length 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 AR-15 pattern firearms in 5.56 NATO and similar calibers, and is compatible with Mil-Spec dimensioned butt-stocks.  This kit should not be used in conjunction with a standard “CAR” length buffer.  The use of a shortened buffer in this special kit will allow the bolt carrier key to collide with the receiver and can damage the rifle.

Note: Griffin uses 17-4 Stainless Steel as material for our castle nuts. This is an incredibly strong allow, 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.
