When I fire my M63 the trigger "sticks" in the pulled position. All I have to do is tap it lightly with my finger and it fires the next round and sticks again.
- trigger works fine when dry firing
- trigger works fine if I use the forearm plunger to cock it.
- it works fine when I manually cock the hammer back lightly when the rifle is taken down.
However I can reproduce the issue if I slam the hammer back hard when the gun is broken down.
I think it's an issue with the sear or maybe the trigger spring. The sear is shinier then I'd expect so maybe someone fooled with it? Before I just order a replacement sear, sear spring and trigger spring and replace them, thought I'd ask here to get some opinions.
Oh, the gun was like this when I bought it, so it didn't just start happening. Also the internals are clean and lightly oiled. The trigger spring is installed correctly too. It was only 125$ and in great shape otherwise so I took a gamble.
Thanks.
