I was dry friring my gun a bit last night and noticed it no quite resetting crisply. Sometimes it require me pushing backwards with my finger... other times it would take a second for the sear to click up and lock. It also cycled normally some to.

I took the bolt off the valve and noticed it was a tad rounded but not chipped or flattened anywhere. The sear is brand new (maybe 3000-4000 shots on it) and shows zero wear. however when I run my finger along the bolt catch edge... a nice amount of silvery dust comes off my finger. I think this is a level 10 bolt problem... are these sypmtoms consistent with a level 10 bolt problem, or can I hope it's something else?

I had a valve that the dump chamber wouldnt fill and the bolt would be pushed all the way back, and wouldnt catch until there was enough air pressure to move it fwd a little. Where is the bolt hanging up? In front of the sear or behind it?

Try the stock size mainspring just to see if it helps. I know that on one of my pneumags I tinkered with if I didnt release the trigger fully the bolt would hang up sometimes too.

I'll give it a look tonight... hopefully it's something simple like that because I only have 1100psi left.

How old is your bolt spring? They do wear out. A properly fitted level 10 carrier usually doesn't just start having bolt stick after it has been working properly. Leaking yes, bolt stick no. A worn bolt or sear would cause misfires, ie; extra shots, but resetting would not be a symptom of wear on these parts.

i would guess carrier issue first off, second choice would be the bumper needs to be replaced.

the bumper is in great shape, and the carrier and oring are working perfectly, no leaks.

well just becasue there are no leakes doesnt mean that the carrier hasnt gotten to tight. my mag was sticking in a similar way (if i understand your description correctly) and i needed to jump up a carrier size. heck you wont use much air trying it so might was well try
