Sylvan Arms Conversion Block AR15 9mm Sig P320 Fits Mil Spec

The Sylvan Arms Sig P320 Compatible Conversion Block is a precision-engineered drop-in solution from SYLVAN ARMS that transforms your standard AR-15 lower receiver into a 9mm-compatible platform, eliminating the need for a dedicated pistol-caliber lower while maintaining seamless Mil-Spec compatibility and reliable functionality. Designed for easy installation, it fits snugly into Mil-Spec lowers and operates with the same efficiency as a standard rifle magazine, offering simple swap-out capability and compatibility with popular Sig P320 9mm magazines for enhanced versatility. Constructed from steel and 6061-T6 aluminum with a black anodized finish, this conversion block weighs 4.2 oz and provides a robust, field-ready upgrade that supports reliable performance. Note that it does not include last round bolt hold-open functionality and requires a 9mm upper receiver for proper operation, ensuring a precise fit in your existing platform. Upgrade your AR-15 with the Sylvan Arms Sig P320 Compatible Conversion Block for streamlined caliber conversion, peace of mind with a 100% satisfaction guarantee, and the reliability of Sylvan Arms' limited lifetime warranty.
