Evolution Gun Works Block Thumb Safety Machined from Barstock Blued

Evolution Gun Works Block Thumb Safety Machined from Barstock Blued. We saw a need for a cleaner more solid design as a result of consistent failures of inferior cast and MIM thumb safeties currently on the market. The only way to keep the safeties as straight as possible is to heat treat the steel and then machine it in the hardened condition. The thumb safety is serrated for better gripping capability. Our thumb safeties are machined in one of our twelve CNC machines Specifications for Evolution Gun Works Block Safety Selector: Manufacturer: Evolution Gun Works Fabric/Material: Steel Hand: Right Gun Type: Rifle Additional Features: Heat treated Serrated Package Contents: Evolution Gun Works Block Safety Selector Evolution Gun Works 11319: Block Safety Selector Blued
