I installed the Rifle Basix trigger today. It is a true drop in replacement. It took me less than ten minutes from start to finish. The pull is crisp, clean and light. I don't have a pull gauge, but at the lightest setting it is too light even for me, and I like light pulls on my hunting rifles. The pull weight is easy to adjust from the bottom of the trigger without removing the action from the stock. There was no filing or grinding of the safety ledge required, and the safety clicks into all three positions positively. I wish they made them in stainless so it would match the factory trigger, but since it works so well it doesn't bother me. My only question is - if Rifle Basix can mass produce an outstanding replacement trigger that doesn't have to be fitted, then why can't Timney?
