Bolt moves forward when trigger is released

[Slick_Willy]

Hey guys, I was wondering if you could help me with a question? I was doing some maintenance on my lvl 10 classic today and I noticed when I release the trigger after a shot, the bolt moves forward just slightly. I would say maybe 1/16". It's not enough to cause a leak or keep balls from feeding into the breach, but enough to be noticeable. Is the normal?

I read of similar situations on other posts, but in my case, I can rule out missing a rail bushing or improper torque on field strip screw. Both are there/ok. My sear doesn't look worn to the eye, but when I lined it up with the on/off pin and bolt shoulder, it looks like it's 1/16" too long. Is that a normal tolerance? Could the sear literally be stretching? Could the bumper be wearing thin, moving the bolt shoulder closer to the on/off? It doesnt' seem like the bumper is a very compressable material...

Any help or thought would be greatly appreciated.

Is it firing properly?

Yes, it is firing properly. The lvl 10 is tuned, and there are no leaks (with or without the trigger pulled). Other than the slight movement forward, the bolt action is perfect.

The bolt will be pushed forward when air is in the dump-chamber, and the sear's job is to keep it from cycling.

If it is as little as 1/16th of an inch, I'd say it sounds normal.


Just keep an eye on it to make sure the movement doesn't increase.

Word to the wise....

If it's not broken, don't F with it.
