KNS Precision, Inc. AR-MCX Adapter with Flange Stock Adapter, Matte Finish, Black

Enables seamless mounting of Picatinny-style stock attachments, such as the SIG MPX folding stock or brace, by replacing the standard AR15-style buffer tube. Ideal for firearms that don't rely on an in-line buffer spring, providing a modular alternative for accessory attachment. Consists of an externally-threaded adapter plug that securely fits into the threaded buffer socket or ring on your weapon. Includes an adapter rail section that slots into the adapter plug, fastened together with a hex-socket bolt and lock washer for reliable stability. Specifically designed for applications where the carrier and buffer tube do not extend beyond the receiver ring, ensuring compatibility without interference. Not suitable for standard AR15 lowers paired with MCX uppers, making it a specialized solution for targeted setups.

Features:

• Standard configuration AR15 style rifles will not function using this product.
• Incorporates a flange in the base of the picatinny plate.
• Allows the use of a standard takedown pin, detent, and spring on traditional AR15 lower receivers.
• This product will not work with a standard AR 15 lower and the MCX upper.
• Intended only for applications where the carrier and buffer tube do not protrude past the receiver ring.
