Kns Ar/mcx Stock Adapter W/out Flnge

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. Developed by KNS Precision, Inc., this adapter addresses a critical need for operators and gunsmiths who require cross-platform modularity without sacrificing mechanical integrity. Whether you're building a specialized rifle configuration, retrofitting an existing platform, or maintaining multiple firearms with unified ergonomics, this adapter eliminates the need for platform-specific stocks and reduces inventory complexity in the field or workshop.

This adapter functions as a direct-mount interface that accepts standard AR-pattern stocks while allowing installation on MCX receivers or AR-compatible systems requiring MCX geometry. The flange-free design reduces overall profile and weight 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 or increase failure points. The 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.

Law enforcement armorer teams, military gunsmiths, and civilian shooters building modular platforms will appreciate the efficiency gains this adapter provides. Installation requires basic mechanical knowledge and standard gunsmithing tools; compatibility verification with your specific receiver geometry is recommended before purchase. The flange-free configuration makes this ideal for users operating in confined spaces or those prioritizing low-profile aesthetics. When sourcing tactical components, this adapter represents a reliable solution for extending your rifle's versatility across multiple platform ecosystems without compromise.
