What's the best way to assess a 700's trigger is okay. I own one 700, a family heirloom that is shot very little and would like to verify that it's okay. Like all 700's the trigger pull is remarkably good. Will a simple function cycling test be enough, or should I tear it down a bit and look at sear surfaces, etc. ?
There are three test procedures recommended which I will attempt to briefly describe:
1. With the rifle cocked (and of course unloaded), put the safety on and pull and slowly release the trigger, then push the safety lever to off. See if the firing pin falls. Repeat several times.
2. With the gun cocked, position the safety lever between on and off. Pull and release the trigger slowly. Flip the safety lever to off. See if the firing pin falls. Repeat several times.
3. There is a little bare metal area under the trigger guard between the trigger and the bolt release button. Cock the rifle and put the safety on. Take a small screwdriver and push on that little area ahead of the trigger and then release. You will feel it move slightly. Remove the small screwdriver. Pull the trigger and slowly release it. Listen carefully for a faint click. If you hear it, that is not a good sign. Move the safety lever to off and see if the firing pin falls. Repeat a few times.
My rifle passed all three tests, not a whisper of a click from test #3.
It's not a 100% guarantee of safety if your rifle passes all three tests, but it should at least indicate whether or not the components in the trigger are engaging properly.
As I earlier mentioned, some believe that the major cause of 700 safety failures and unintended discharges is not so much the trigger design, but the presence of dirt, lint, etc. in the trigger mechanism. And Bubbas messing with the trigger.
