Stock Bolt, Why does it not re-cock sometimes..

[JOESPUD27]

Hey, I've had my M98c for about a year now and in the past month or so i noticed that everyonce in a while it doesn't re-cock. Its happened when i'm shooting fast and slow. I heard it was the two screws on the "not letterd" side. I tighted those but one of those scews seemed stripped and i've never tighted it b4 today. I went ahead and snugged up all the other screws though. I just wondered if anybody else have had similair problems and how they might fix them. Thanks

low on co2? that sometimes does it...

If it's stripped, that 'could' be a minor problem. Those 2 screws go to the valve. they keep it firmly in place. If it is not firmly snug, then you could have problems like that. Pretty much performance is hindered.

If that is stripped, you might need to replace the valve.

Also, a possibility is low on air source. Since it's JABB in needs a certain amount of gas to push the bolt back. And when low on air, that will sometimes happen. Usually go into full/auto type of mode.
