KSC UPS Fullsize problem
 

I only have one mag so this is tough to troubleshoot.

I get about 6 or less shots and then I am outta gas. I tried another propane bottle with no luck. I can not feel or hear any leaks. Is there some way that is releasing too much gas or that the mag is screwed and is not holding much?

Any ideas
?

If it is releasing too much gas, you should be able to see it actually blowing out of the gun around the bullet eject port. You will definetely be able to smell it also.

Your mag might also might not be taking enough propane because of the adapter or nozzle problems.

I having the same frekin problem with me 5.1 WE hicapa....real annoying stuff.

My usp ejects all the gas on the last bb.

How long are you holding the propane bottle in? You should be able to hear the propane moving between the tank and the mag with air moving back up to replace it.

Keep the bottle on until you can't hear the sound anymore. A good nozzle should also not be leaking any propane when you are applying the propane adapter. It will leak a bit when you remove the adapter. Feel free to also do it once or twice more to make sure it's topped up.

you should keep holding it untill infill valve on the mag starts spitting liquid propane. make sure you are filling the mag inverted.

if you are shooting it in this weather, that might be the cause. cold weather messes with gas consumption big time

I'll try that. I have been filling until I can't here it going anymore. doesn't take but 5 secs or so.
