Hey All—First Post, I recently had the trigger mechanism on my Remington 721 replaced as the old one was labeled unsafe. Remington (the ones who did the trigger replacement) claims they cleaned and test-fired the gun but I doubt it. Upon trying to shoot it today, I would get the “click” of the firing pin but no shot. I took the gun to a smith and he said the firing pin is no longer extending far enough to strike the primer. He also pointed out that the "Firing Pin Head" (circled in red below) is seemingly extended outwards even when the gun is not ready to fire. I included a picture of my gun (with scope) and a standard 721 (without scope) below. You can see how the pin head is much further out on my gun. Both I and the smith took out the firing pin but neither of us have been able to figure out this issue. Has anyone run into this problem before? I can probably send the gun back to Remington but I'd prefer not to wait 3 more months. Any info would be appreciated!
