hi matt, sounds like mine but mine has the 8 shot mag in .177 , I have seen a couple around which I think are the same but not many in .177 amd mine even says its a 22 on the plate!, and yes the adaptor on the end of the barrel which joins it to the air cyclinder is loose, hense me asking about the braces but cant seem too find one for my gun, but it is getting on a bit now so im not surprised, and I will try to send some pics if I can work out how to do it!
thanks for the feedback, John. and Im trying me best with the braces!
