Mosin bolt stop question

[rp55]

So I was out blasting my M44 and after 8 shots the bolt came all the way out and the trigger was just wobbling. When I got it apart I discovered that the bolt stop end of the sear had gotten wedged outside of the hole it fits through in the receiver. It popped right back in with a screwdriver but I am worried about this recurring. Anyone seen anything like this? Would filing or polishing the bolt stop be the way to stop it?

The bolt stop is located on the top of the trigger; it is not part of the sear.

If the sear is getting stuck on the bottom of the receiver, you've got a major issue going on. Is the sear screw tight? Did someone attempt to "tune" the trigger by sticking shims under the sear or bending it?

I'd swap the sear and trigger with a replacement and see if things improve.

That piece of metal that projects up at the upper left of #1 (the sear/bolt stop) is what I am talking about. It fits through a hole in the receiver and it appears the recoil "bounced" it out and it caught on the edge and did not go back in.

Sounds like your sear screw was loose.

Nope. It was very tight. Everything was normal except for that tip being outside the whole.

I asked Ted for a clarification on the sear/bolt stop question and it was labeled incorrectly on the web site, so he fixed it.

Is your sear original or has someone "tuned" it up and possibly bent it? If there are no shims under it, and the screw is tight and you have a pivot pin installed in the trigger, I would order a replacement trigger and sear from one of the online parts sources and try it with the new parts.

I have quite a few spare triggers and sears, so if you are ever planning to shoot at USI in Concord I could bring an extra sear and let you try it out.
