New-design safety blocks the trigger, not the sear. There’s no way to move the trigger when it’s on safe, virtually eliminating the risk of accidental sear release when you take it off safe. Right-hand (RH) and left-hand (LH) models available, both with a 3⁄8” wide, grooved trigger shoe that improves feel and control. Choose a Straight shoe preferred by some benchrest shooters for its more precise finger contact. Adjustable, 11⁄2 to 4 lb. weight-of-pull, creep and backlash. Fully assembled to save time and labor. Includes bolt release.
