My mag wont shoot

[Breeze]

I am in a bit of a mental pickle, my mag will start shooting and then stop. I turn the asa off than on and it will shoot for a few more shots and then stop again. I have a level 10 installed with xvalve and ult kit.

I have 2 shims and he carrier with no markings ( gun is not leaking at this setting so I let it be)

tried with both gold and red mainspring with similar results

the ult has 4 shims in it

Does anyone know what could be causing this? I am heading to work but I will update with any suggested fixes later. Thank you for all the help.

i have the same issue with one of my ult mags, i put a regular on off and its fine so im guessing its going to be an issue with your ult...i have no spare parts so i cant fix mine, someday i will

Well first thing first, you could be starving the valve with your ASA on/off. Sometime the on/off will push the pin on the tank too much and actually cut the air flow.

Thanks for the tips guys, I checked the tank and it is good. I did fiddle a little more with the shims and carriers on the level 10 and seems to be fine now, or at least for the moment. I replaced the on off as suggested and created a fully automatic death machine but I have no need for that so I guess I will need to work on dialing in the ult and not through a different assembly in. Thanks again for the help.

You are getting bolt stick. Take all the shims out of the powertube and reduce the ULT shims to 3 to start. Then use the largest carrier size that does not produce a leak down the barrel. Always use the same white carrier oring in each carrier you try. Once you find the largest carrier that doesn't leak, you can try 4 ULT shims in your ULT again. Don't bother with the level 10 shims in the powertube.
