At risk of upsetting the vast majority of people who think a springer should be heavy, I decided to challenge myself and build a lightweight TX, that incorporates some of the alterations I have made and tested over the last few years , my aim being a low recoil/surge accurate light TX. So I have manufactured an aluminium action, spec: All ally action, under lever, & shroud, Ally and steel 22mm comp tube , skirtless Piston (utilising a modified aussie Hw 45 seal) Decided to go skirtless to give me a wide choice of spring, thats not to say it will stay that way! 90mm stroke extremely short ( 4mm) transfer port, that has an internal o ring in the end of the comp tube , the comp tube has a steel insert that sits flush to the barrel when cocked seating the pellet , and at present a cut down Mark 3 spring, Under lever has magnetic catch to minimise interference with the barrel, I think that's about it, oh the barrel, is a cut down CZ s200 making it 2" longer than a standard one , fitted into the new shroud makes the gun 20mm longer than a standard full length Shot cycle is nice and soft very fast , early days yet only put around a hundred through it . It weighs 7.5 lb. in the beech stock, standard is in the region of 9lb. Further this is going to be my FT gun if all goes well so I have made an ally adjustable target stock to go with it that is very light, no pictures of the stock yet as its away being powder coated , Pictures to try and show better what I have been up to , hope you like it.
