bolt stick?

[keiko_819]

so i aired up one of my mags today and i took a shot and it seemed like the on/off didnt want to reset...i turned the air off then back on and it would do the same, only one shot and then nothing, any ideas...thanks

Did you look down the feedneck to verify that the bolt wasn't fully reset? If so, the first thing i'd check is the field strip screw. If it is too tight, the bolt will stick.

I finally got some air and checked to make sure the frame screw/feild strip screw weren't to tight...it seems like the valve takes a sec to get the air it needs to recharge...it shoots a couple or few times then feels like the on/off in the valve doesn't fully reset...any other ideas?...

Check to make sure it's the bolt needing to be reset. Fire, and when it sticks, try to physically "cock" the bolt back by using a squeegie or swab. If it clicks back, even just a millimeter, and is ready to fire again, then it's bolt stick. It could be a carrier o-ring that has swelled, a worn bolt spring, a too-tight field strip screw or frame screw, or a whole host of other minor things. The first thing you might want to try (after checking the field strip and frame screws) is to open up the powertube and put a drop of oil directly on the carrier o-ring. Then see if you can shoot multiple shots in quick succession (I'd advise without a barrel on, pointing down or into a paper towel because it's going to fire out an oily mist for a few dozen shots).

Sounds like bolt stick caused by a carrier oring that is too tight. You should tune your level 10 bolt. Remove all the powertube shims and install the largest carrier size that does not produce a leak with the oring that you are using. Always use the same white carrier oring in each carrier that you use.
