MPN: AR-MCX Adapter w-o Fla
The KNS AR/MCX Stock Adapter without Flange is a precision-engineered interface component designed to bridge incompatible stock systems across AR-platform and SIG MCX platforms. This adapter is ideal for operators and gunsmiths who require cross-platform modularity without sacrificing mechanical integrity. It serves as a practical solution for building specialized rifle configurations or retrofitting existing platforms.
This adapter functions as a direct-mount interface that accepts standard AR-pattern stocks while allowing installation on MCX receivers. The flange-free design contributes to a low-profile design while maintaining the structural rigidity necessary for reliable operation under tactical conditions. KNS Precision's manufacturing standards ensure tight tolerances and consistent fit, minimizing rattling or play that could degrade accuracy.
Law enforcement armorer teams, military gunsmiths, and civilian shooters building modular platforms will appreciate the efficiency gains this adapter provides. Its compact footprint—measuring 4.5 × 1 × 6.5 inches and weighing just 0.13 pounds—makes it an ideal solution for SBR (short-barreled rifle) builds or space-constrained mounting applications where every inch counts.
