The Strike Switch is a patent pending modular safety selector designed from inception using human factor considerations to aid positive on safe on fire manipulations. The unique toggle action allows one to quickly engage the safety when moving positions without altering the firing grip. The extended lever arm serves as an index point and thumb rest in either position. Adding to the modularity the Strike Switch is end user configurable to use a 60 or 90 Degree throw configuration. The levers are machined from lightweight but strong aircraft grade aluminum for weight savings while the safety shaft itself is machined from high strength steel for a lifetime of use. *Note: Will NOT fit .308 pattern lower receivers with shelf (DPMS Bushmaster) ATI Omni Hybrid (all calibers) Seekins Precision SP 223 Gen 2 or F-1 Firearms Receivers without modification to receiver or selector switch.
