I just picked up a 700 BDL from my friends collection after he passed. It is a .243 with a heavy barrel. I never knew my friend had this rifle. It has a light aftermarket trigger in it. I cannot find the bolt release button. Any ideas? He removed the safety when he installed the light trigger and I want to replace it with a new Timney with a safety. One other thing, this gun has the hinged floor plate and the button inside the trigger guard releases the floor plate.
