I have been experimenting with different TP seals, and so the barrel has been off an on many times, maybe a dozen. Today I noticed that I could shift POI left and right over a range of about 2" from 10 yards (rested) by simply pushing the muzzle a bit either way. This obviously isn't good, or right. Barrel band screw is pretty tight.
What needs to be done to fix?
New O rings on barrel?
Second grub screw into breach?
Glue barrel band to CO2 tube?
Get metal barrel band...?
All of the above.... or which ones ?
Thanks.
