KNS Precision Compact AR/MCX Stock Adapter with Flange

The KNS Precision Compact AR/MCX Stock Adapter allows users to mount a Picatinny-style stock or brace — such as the SIG MPX folding stock or SB Tactical FS1913 — in place of an AR-15-style buffer tube. Designed for firearms that use the AR-15 buffer tube attachment point but do not mechanically require the tube, this compact version locks into the rear AR-15 receiver stock plate pocket without the added rail length of standard AR/MCX adapters. Finished in black.
