Problem - mags not firing

Here's the problem: when I aired up my mags about 2 months ago, I could shoot them with no problems. Now when I air them up, they will not shoot. There are no leaks, but the trigger feels spongy and hard to pull. One of these I could fire one or two shots and then it would do the same thing. My on/off pins are not bent. I'm not too thrilled that they worked and now don't work for reasons beyond my comprehension; these are my loaners and I need guns that don't crap out on me. Any help or advice would be much appreciated!

Have you tried changing the o-rings in the on/off? perhaps theyve swolen or fallen out of place.

I always make sure to put 3 drops of oil in the ASA before gassing them up; should I be putting more? I am 90% sure the on/offs are put together correctly and I have not taken them apart to service them since they were working. When I pull the trigger I'm using the same effort it takes to pull an RT mag trigger but there's no release of gas, so I think swollen o-rings could be the culprit. If this is the case, do I just replace them?

Bolt stick. Take a dowel rod or squeegee and push the bolt back. You will here it click and should be good to go. If it happens alot replace the bolt spring.

I thought the bolt had to be stuck forward for it to be called bolt stick? When I gas one of these up the bolt is all the way back and held by the sear like it should be.

Tank has a LP reg installed.

Under 800psi in your tank.

Velocity adj too low.

Those are all potential problems that can cause what your experiencing.

You're either using an LP tank or your bolt is stuck. Check your tank first, that's usually the issue here. Mags need 800psi+ to run on.

If that's not it, it's bolt stick. Take the valve out and make sure the bolt and spring are clean. Put it back in and LOOSELY tighten the quick-strip screw. If you overtighten it you can cause bolt stick.

Bolt stick does not mean it's caught in the forward position. It just means the bolt is sticking somewhere in its operation. In a Mag it means your pressure is too low or something is blocking the bolt from moving forward.
