RE shredding the barrel O-rings.... Debur the transfer port and setscrew hole carefully on the inside.... Then get a metric screw that fits the setscrew hole and sand the end smooth.... Install it in the breech FLUSH with the inside of the setscrew hole, and when you push the barrel in, the O-ring won't shred.... Remove it and install the setscrew.... If you put a collar (or washers) on it to make it stop flush you can also use it for removing the barrel, but if it sticks down too far you will still shred the O-rings and can scar up the barrel too....

I use 012.... 3/8" ID x 1/2" OD x 1/16" nominal sizes.... You can probably stretch a 011 into the grooves and they may be less prone to shredding as they won't stick out much (if at all).... don't know about sealing though....

012 fit too loose on mine. 011 stretch into the barrel grooves and yet stick up enough to seal. Try both for sure.

An oring kit is a good thing to have around.

We picked up 4 co2 cap seals
They are just regular seals
We are putting an order with Eric
We are going to be getting 2 QB78D seal kits and a 2240 seal kit
Should be good
