Do It Yourself Trigger Upgrades For Ruger Bolt Guns
Easy-to-install, triggers are investment cast from A-2 tool steel, then heat-treated and drawn to Rc 50-55 for long-lasting reliability. Radius ground sear surfaces help eliminate creep and enhance overall smoothness. Adjusts for weight of pull and uses the factory safety with no alterations. RU-MK II fits all Ruger M77® MKII rifles with 3-position safety. RU-R replaces the non-adjustable trigger in 77/22® and 77/17® rimfire rifles. RU-VT fits rifles with two-stage factory triggers.
