KNS Precision Compact AR/MCX Stock Adapter – AR-15/AR-10/SIG MCX

The KNS Precision Compact AR/MCX Stock Adapter enables installation of folding stock mechanisms on AR-15, AR-10, and SIG MCX platforms. This adapter provides a solid mounting interface for aftermarket folding adapters while maintaining proper buffer tube alignment and allowing continued operation of the firearm's cycling system. Shooters seeking a more compact storage or transport profile will find this adapter delivers the necessary framework for folding stock conversions without compromising structural integrity.

Precision-machined from steel with a durable black finish, the KNS Compact Stock Adapter features a flange design that ensures secure attachment to the lower receiver. Installation requires basic armorer-level familiarity with AR platform components and receiver extension removal. The adapter is designed specifically for compatibility with AR-15, AR-10, and SIG MCX receivers, and provides the mounting platform necessary for select folding stock systems. This is an adapter component—a separate folding mechanism and stock are required for complete installation.
