KNS AR/MCX Buffer to Picatinny Rail Stock Adapter with Flange

The KNS Precision AR/MCX Buffer to Picatinny Rail Stock Adapter with Flange lets a shooter mount a Picatinny-style stock or brace, such as a SIG MPX folding stock, in place of a standard AR-15 buffer tube. It suits firearms that use the buffer tube attachment point for stocks and braces but do not mechanically need the tube for an in-line buffer spring.

The kit has two parts and an attaching bolt. An externally threaded adapter plug fits into the threaded buffer socket, and an adapter rail section slides into the plug's slot. A hex-socket bolt and lock washer secure both pieces to each other and to the firearm. The adapter is black and intended for AR-15 and MCX platforms where the bolt carrier and buffer tube do not protrude past the receiver.
