Mike, Thank you. This is a Synrod, ie Gen2 with the cone shaped baffles and spring. I replaced them and I know they are .22 because I ordered them. I have no issues at this time with the gun. The end cap may have got clipped from double feeding and shooting out two pellets at the same time. It's happened before. The clipped baffles were in the gun when I got it ... but not anymore. Cheers
