Product Description
The KNS AR/MCX Stock Adapter (without flange) is designed to let you replace an AR-15 style buffer tube attachment with a 1913 Picatinny-style stock interface for compatible firearms that do not mechanically require an in-line buffer spring. This modular kit allows mounting of picatinny-style stock attachments (such as a SIG MPX folding stock) in place of a buffer tube. The kit includes an externally threaded adapter plug that installs into the threaded buffer socket/ring, plus a rail section that locks into the plug and is secured with a hex-socket bolt and lock washer. Please note the critical compatibility restrictions: this adapter is not for standard AR-15 rifle configurations, and it will not work with a standard AR-15 lower paired with an MCX upper.
