This Karl Kenyon-style benchrest trigger is a well-kept secret by competition shooters. Made from 01 tool steel, it was designed to have a robust housing for a trigger that lasts longer than the rifle it's installed on.
It is a purpose-built trigger, with no equal in the benchrest arena. The single-stage 6oz-3.5lb pull weight is easy to adjust with a small allen key, usually accessible while the trigger guard is in place. This means you don't have to disturb your tuned setup if you want to adjust trigger pull on the fly.
PT&G manufactured the trigger, fits Remington 700 style rifles.
