Is the cutout missing for the firing pin? See post number 3.
It's my buddie's rifle, it has 30 rounds through it. It's a brand new production Springfield SuperMatch. The tail of the firing pin is rubbing on the bridge, is showing burrs and the firing pin gets hung up on the bridge.Russ did you just get this rifle? What's it's history....Something is not right in dodge city. How does it function?
While both of my pre-ban M1As look like the second pic that was posted, I really can't see how the extra clearance in the pic above would make any difference. The important thing is that the FP is held back before the bolt starts to rotate into battery. Am I wrong in this assumption. dozierDito leadbug. Russ69 if you are having trouble I'll pm you my email address and send them to me and I will post them.
Ok so here is russ69's safety bridge picture.
what is SAI doing to these bridges lately?
I am not an expert but my interpretation, from reading Gus Fisher's info, is that it doesn't take very much interference from the bridge to stop the bolt from going in to battery. So yes, the primary purpose of the bridge is to stop the firing pin from moving forward before the bolt is in battery position but if it is burred or misshaped it can also stop the momentum of the bolt and or firing pin from moving forward as they are supposed to.While both of my pre-ban M1As look like the second pic that was posted, I really can't see how the extra clearance in the pic above would make any difference.

I didn't anneal or heat treat the area that I worked on and so far I haven't noticed any unusual wear but it has only been a couple months. Then too I only took a very little material off.RAMMAC, was it necessary to heat treat the area after your modification, or was the repair so shallow the original heat treat remained unaffected?
