The AR/MCX Stock Adapter from KNS Precision provides a modular solution for mounting a Picatinny-style stock attachment or brace in place of an AR15-style buffer tube on firearms that do not require an in-line buffer spring. The kit includes an externally-threaded adapter plug, an adapter rail section, a hex-socket attaching bolt and a lock washer. It is intended for use on buffer-less systems that rely on a takedown pin spring or detent and allows common Picatinny stock/brace options to be fitted where a buffer tube would otherwise be used. This product will not work with a standard AR-15 lower and the MCX upper and is intended only for applications where the carrier and buffer tube do not protrude past the receiver ring.
