You just need to smooth at the end of where you drilled, not where the O ring seats, just past that, I bet there's a sharp edge there that is catching the pellets

i dont think this would work because the catch point is right where the o ring sits and the barrel opens. to get a tapper where I need i would have to have a way to add material back .. ill post a pic

can you take the breech and barrel off while the c02 is still in the tube?

Yes

this is the type of reamer i'm using they're pretty soft so it will only do a couple of barrels and you do need to polish the leade a fair bit to get the marks out but it gets you in the right ball park i get the leade right before drilling the port

Yes but, why would you want to? Handling any device that has 800+ psi in it while it is being disassembled is a bad plan IMO.

That's true BDS, but with the way these are built the risk is pretty low if the safety is off and the hammer isn't cocked, nothing above the tube has anything to do with holding pressure... just as dangerous as handling it assembled...

woody67 · November 19, 2013, 01:45:08 PM

Even if you cock the hammer and pull the trigger, you just get a blast of air that goes straight up. Absolutely no difference than it blasting straight out of the barrel.

People do this all the time. Ive done it with my marauders countless times while tuning and installing orings etc.
It is not unsafe to take the breech off while a co2 cartridge is in.

Might as not well not even own one based on your advise.

How do I post a pic from photobucket? I have a few more problems I'm afraid

kraaash · November 20, 2013, 09:55:21 PM

Mm got it... So first question is about this Mellonair prob.. It seats a bit different than the stock one shown next to it, it's a bit bigger, is this as it should be? This is suppose to be for 177

kraaash · November 20, 2013, 09:57:10 PM

The other question I have is a breech problem, it doesn't sit all the way down towards the front, although it doesn't seem to have any air escape.

kraaash · November 20, 2013, 09:59:40 PM

Third question.. I think my valve also from Mellonair is messed up.. I have it where it needs to be for the grip frame and screw to install and the outlet hole is off on an angle from the tube hole.. By a lot, am I going to be able to get this to work?

I think the valve misalignment is from Crosman my 1322 valve was slightly off also. but not as bad.

The valve is a flat top I ordered from Mellon

Every valve i have ggotten from mellon has been off like that.
He told me to twist it back/unscrew it just a bit and it should line up and work perfectly..if it doesnt im sure he will send you one that works.

Can you tighten down the front screw in the breech(where the pellet gets loaded)? That should tighten down the breech. Sometimes i clamp it before tigtening. Could be that the mis alligned valve is causing the transfer port to not seat correctly, resulting in keeping the breech from tightening down correctly.

Thx.. Should the mellonair prob be so much firmer to seat in? The stock one slides all the way in.
