vavle/ cocking probs

[cockarock]

i just got a micromag r/t off of ebay and it has a problem.

the valve doesnt seem to be getting enough pressure. my tank is a high output nitro tank and it is full. but the problem is that it doesnt get enough pressure.

i changed all of the o rings in the gun and made sure everything was clean, but it still doesnt work.

also there is a small air leak which comes out of the front of the marker

any help is greatly appreciated

thanks

Do you have a gauge that makes you think the valve ins't getting the right inut pressure?

Are you having an issue where the bolt isn't resetting? Can you push the bolt back with a squeegie?

aight it doesnt sound like it is getting enoung pressure alos when i tried to fire some rounds they just got stuck in the barrel

yes i can push the bolt back with my finger

Make sure that there aren't any restrictions between the bottle and valve. Make sure, and I know that it sounds obvious, that there is air in the tank. Make sure that the velocity is turned up on the marker.

Use the short gold spring. The longer springs need the velocity adjuster to be turned up to work which equals a higher FPS. Dose it have a L10 bolt? If so switch to the next tightest carrier while using the same o-ring. after that tune the L10 by adding shims and placing a squigee about 1/4" away from the bolt and fire it. If it dosen't add 1 shim at a time until it dose....

Is this an old school R/T, or an R/T pro? What grip frame does it have on it?

We had an old R/T with a Benchmark frame and we had to re-adjust the trigger stop and the sear length because we were short stroking it causing the sear not to catch the bolt all the time.

turn up the velocity
