    One I handled and shot had the chisel at a very off horizontal angle and grouped appallingly, not something I’d expected from a rifle that cost more than my car .. their QA & QC must be dreadful to have missed that.

    The trigger cage was welded on out of alignment on the Evolution I had.
    Too many airguns!

    I've never had much contact with a Vulcan but I have a Stingray and bits of an Exocet, Explain your findings please.
    Far too many rifles to list now, all mainly British but the odd pesky foreigner has snuck in

    Sorry, cant comment as I never had an Xocet. I liked the Vulcan well enough but didnt hang on to it for long. Cant remember the reason for parting with it. Probably too many air rifles at the time.

    The early Theoben were a right mix of parts. They used both BSA and W&S bits including the BSA cocking link witha bit of plastic sandwiched between two thin plates. I wont mention the problems with them not holding a charge as some may remember that costly episode.

    The best way to do this and it give a instant improvement is to make sure the bolt you buy is already going throught a hw99 breech… sorry I had to, I did actually think of this myself as I’ve had a bsa Supersport custom with the bolt but they are finicky and have fine shim washers to get the tension right and aren’t as good as say a hw or webley where you can just set tension and lock it in.

    I know you did, I bought it off you, I still have it and it's lovely.

    Yes if only they had standardised that as the lighting setup trigger and all, would of been much better.

    I've been saying that for years and if they had continually improved on it as well, then it would have given a few other makers a run for their money.

    I think it's one of the later Gamo units.

    P.S.... The more you read about them, the more it would seem that many of the British break barrel designs were a classic case of "snatching defeat from the (breech) jaws of victory".
