    I've also got a Crosman Benjamin with the "hidden screw" (Google it !) which prevents the pellet "nosediving into the breech screw hole (less of an issue in .22)

    Agree 100% on the TRR Robb trigger, had to do some work with it but it's perfect. I also have the GMAC MkIIA trigger setup, good but twice the price of the TRR Robb one. IMO the trigger is the BIGGEST area for improvement.

    No issues getting bits from the US, check out ; Alchemy Air, Alliance, Mellon air (has great stubbly barrels)

    Enjoy (dont spend too much !
    I found the rare earth opposing magnet triggers work very smoothly..

    I chap has emailed a couple of pics of his custom stubby 2240's (he's done more than one) and he shortened the valve and reemed out the co2 end cap to get them even shorter!

    as mentioned to get a stubby really small you need to shorten the valve case and bore the co2 cap out so the 8g cart sits in the cap
    to use an 8g you'll also have to take out the co2 face seal out bore the seal opening a fraction and refit the seal-the reason is the 8g co2 tip diameter is a fraction bigger

    my mate Patty sells the magnetic triggers or did
    I prefer a light spring and guide
    many say to use the std sear spring but make it take a set by fully compressing and leaving for a bit then fitting a spent .22 case -this does improve it but it's still poor in reality

    TB I did this a few months ago, made a stubby to take 8g carts. Cut and brazed the gas tube as I don't have a lathe. Didn't need to modify the valve. It also takes 8g nitrous oxide capsules (at slightly less power) so it's Dual Fuel
    Not a huge loss in power overall.

    The rear sight arrived from the states in double-quick time. I must say, I love the looks! I can't wait to give it a go

    Nice one. I have a MIM on mine too. Did you shorten the gas tube or just the barrel?

    Wow! That's proper Thunderbirds stuff! I reduced the tube by about 11mm and the plug to suit so its the shortest that'll work with 12g. Reducing the frame/handle is next.

    Someone of your talents should have no trouble cutting and rethreading the tube (obviously the better route if you have the facilities for it) to take 8g carts. It's not a lot but it does make a big difference to it's perceived size.

    That is sweet. Wish they made them like that as a factory item.

    I hadn't looked in for a while, Nick.

    Lovely.

    I've threatened to buy one of these sights for ages now but haven't got round to it. When funds allow I'll get one for sure.

    Please, please don't sell this prior to The Bash and bring it along.
