Just going to mention this..

Evidently a .177 pellet, if bobbled during loading, can fall though the reciever and into the hammer/valve area of a QB.

Fustrating is kind of mild.

I think Homer Simpson said it best when he uttered, "Doh!"

It's worse when you drop one into your Duff beer,doh.! Ed

Hehe, yea, that can happen all right.  It can even happen on a .22 QB if the bolt has been bobbed and probed.....don't ask me how I know that....doooooh!

Happened to me when I let a friend shoot my .177 QB.  My QB has the bolt probe mod and the opened up passage, so the pellet dropped right through.  The pellet was blocking the action of the hammer, so there was no way of releasing the remaining CO2.  I ended up removing the trigger assembly and just worked the bolt back and forth a few times and luckily the  pellet popped back into the breech area.  No need to experiment with novel new ways of degassing the QB.

Really no need to drop the charge for something like that, the screw and block for the hold down stud will keep  the valve together and if you do happen to hit the valvestem it just farts at you.

That is good to know. Everything I have read on the QB says to degass before starting work, so I was expecting a unpleasant suprise during dissassembly of my stuck QB.  Actually, it is the one you tuned up for my wife.  I shortened the stock,  put a scope on it for her, and then invited her to try her hand at shooting the rifle.  She promply started stacking on shot on top of another as I stood there open mouthed.  I'm sure she was thinking: "so, what's the big deal here?, this doesn't seem that hard to do?"  The good thing is that she really likes the rifle!  FYI, I had asked Mike to work up a QB78 with really smooth cocking action as my wife has a bit of arthritus in her hands and was having difficulty with my stock QB.  What he sent us was perfect for her, and as usual, did more work on the rifle (like the bolt probe) than we were expecting.  Thanks again Mike

These things are not parts for the space shuttle, if you need help please feel free to ask me or anyone else that knows the CO2 guns for advice. Most of us are willing to give away any thing we know so that you can work on them safely. Ian in England knows as much as I do if not more, forget his login here but thats another place to look. I felt like most of you until I took one apart, it's unknown territory until you have visited it, once there you see it's not so strange..............

Problem was, the pellet jammed so that the gun wouldn't even make a CO2 "burp"...no way to reduce the pressure short of putting a pipe wrench on the end cap.  Wasn't going to wrench it, so dissassembled the gun (CAREFULLY) until I had the hammer out...and the offending blob of lead that was once a pellet.

Are right..don't need a degassing key...just need to jacke the scope up with higher rights so my fat fingers can more surely load the pellet.
