custom bad air economy, Rear bolt o-ring ?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   When recently taking apart my custom pro I realized the o-ring on the hammer(rear bolt) had some slop to it. There wasn't alot but when I move my hammer back and forth a bit it feels like it's rubbing slightly with the powertube. Also it has been a hog on air latley (500balls on 3000psi 50ci hpa) and I have seen blowby out from behind the hammer when using co2. 

This can't be normal is it?

	500 balls on the tank you describe is about average for stock Tippmanns. Without seeing the blowby from behind the hammer I can't tell if it is excessive, but this is the location that the propellant used to reset the rear bolt (hammer) vents at. If by "slop" you are referring to the slight catch as the rear bolt face enters the power tube that is essentially normal and is indicative of the o-ring being tight enough to seal. If you think it is excessive you should put a couple of drops of oil (not grease) on this o-ring through the opening for the charging handle then let the marker lay on its right side for a while so the oil eventually work its way around the o-ring due to gravity. (Or you could just take the marker apart and give the whole thing a good lubrication.)

	in my experience o-rings are usually tight , i ran out of oil and got to eager so i think it might be a bit worn as i can move it by slightly touching it
