Compatibility Notes Receivers: Designed around mil-spec AR-15/AR-10 lowers using 0.154" pins. Large-pin (.170") Colt-pattern lowers are not compatible. Safety Selectors: Works with standard AR-15/AR-10 safeties; verify positive engagement after installation. Bolt Carrier Groups: Compatible with standard AR carriers; ensure the hammer profile clears your BCG. Pins: Many shooters prefer anti-walk pins for extra security in hard-use rifles (sold separately). Maintenance & Care Keep internals lightly lubricated at pivot/friction points. Avoid stoning or altering engagement surfaces—this may compromise safety and void warranties. Periodically check pin tension and selector engagement, especially after high round counts.
