I am having air issues with my MR2 i use HPA and only minor internal upgrades like a spring kit and shim kit. The trouble that I am having iss that my marker acts like its out of air, it does the long BBBBBBRRRRRRR and then uncocks itself. I have never had trouble with air before, could I be having trouble with the valve or something else? any help or input on the matter would be greatly apreciated.

It should be the valve. Usually uncocking itself is because of the valve.

Any ideas of what could be wrong with it? is there anyway to adjust or fix it? or do i just have to buy a new one?

do different combinations of the shim and spring kit until the problem is fixed, if it inst fixed you can always get a high flowing valve, tell me are youusing a high pressure tank or low pressure?

have you tried pulling on the T-bar when it jams.

I tried but it hard , sometime I need to push on the bolt with something hard. I think it maybe the valve spring.. what do you guys think?

try the light spring, the hard sppring might be give your bolt to much force,

I use high pressure, I tried it with everything stock and have the same problem.

Have you fully stripped and cleaned everything?

are you running a remote or is the bottle screwed into the marker?

Is the bolt in upside down?

Sorry Chnk, I will do that now.

Yes I have fully striped and cleaned everything at the end of each game, and I did it again when i started to have trouble. At first I was using a remote but then I took it off and hooked my bottle strait to the gun, same issues.
The bolt and all internals are in the proper way, I have done it alot before, but just to be sure I dug out the diagrame and everything is in the right way.
Any other sugestions?

look for the electronic sear , it might be used . part #JE12

hmm is it a high pressure tank? if its low pressure then theres your problem,

if its making the blurp sound that means something is restricting air to the marker, check the air hose it could be pinched or something, you can buy a high flowing valve pin,

hmmm weird, im not sure what the problem is, my mr2 did the same thing for a while, but i converted to low pressure and it went away. hmm buy a highflowing valve and vale pin it should cost you like $20, this might fix your air flow issue
