nobby Posted October 8, 2011 Report Share Posted October 8, 2011 (edited) I have an early TX 200 but was thinking of changing the spring with a tx200 mk3 one. Simple question will it fit? It isn't the original spring in my rifle atm so I cannot make a comparison. Cheers Please note in your replies that I'm a complete biff when it comes to these things and blank stares will be used at anything too technical.

fenboy Posted October 8, 2011 Report Share Posted October 8, 2011 I am pretty sure the mainspring on a MK3 does not fit a MK1 without a new spring guide , maybe a daft question but if your gun is a MK1 why not just fit the correct spring for the gun ?

nobby Posted October 8, 2011 Author Report Share Posted October 8, 2011 purely as there was one on ebay for a decent price when I was mooching, cheers for the info Quote Link to comment Share on other sites More sharing options...
secretagentmole Posted October 8, 2011 Report Share Posted October 8, 2011 Stick to the spring for the gun, that way you should not run into any problems of either a physical or legal nature! Quote Link to comment Share on other sites More sharing options...
nobby Posted October 8, 2011 Author Report Share Posted October 8, 2011 Having a bit of trouble sourcing it mole. As I said the one in there isn't the original and would love to get back to how it should be. Plenty out there for the mk2, mk3 and hc but nothing as yet for the tx200. I'll keep looking.

nobby Posted October 8, 2011 Author Report Share Posted October 8, 2011 Thanks fenboy, Have no idea why that didn't come up when I googled tx200 spares. Quote Link to comment Share on other sites More sharing options...
oscarsdad Posted October 8, 2011 Report Share Posted October 8, 2011 U get a new spring in the venom tuning kit which i have fitted to my mk1 TX ...not hard to do at all, just be careful so the spring which is under tension doesn't smack you in the gob when you open up the mechanism!

Polish Posted October 8, 2011 Report Share Posted October 8, 2011 Try a V Mach kit, not sure if they do springs for dated models, you may however be able to order one directly. I have V mached my tx200hc, shoots a dream now, 10p groups stood at 30m! Smoother than Lurpak. Best of luck. Quote Link to comment Share on other sites More sharing options...

secretagentmole Posted October 9, 2011 Report Share Posted October 9, 2011 I am waiting for a new spring myself, as mine has dropped to the 10 and a half foot pound level! I am waiting for Air Arms to get them in though, should be sometime this month! Quote Link to comment Share on other sites More sharing options...

Catweazle Posted October 9, 2011 Report Share Posted October 9, 2011 The TX200 is a very efficient design, the earlier models easily make 12ft/lbs even with very very little spring preload. The MK3 has a different stroke length so the spring may not be suitable. I fitted a ProSport spring to my TX200 MK2, it was slightly shorter and stiffer. I made a Delrin replacement for the standard steel "top hat". To keep it below 12ft/lbs it has no spring spacers at all, and no spring preload to speak of ( just enough to stop the spring rattling ). Unless you are prepared to modify other components and keep a very close eye on power, especially with ultralight pellets like Defiants, they I would advise you to get a standard spring. Before you fit it carefully polish the end faces, this will make the cocking and firing smoother. A small amount of gooey lube on the spring will help, there are special lubes available but I use a quick spray of Putoline anti-fling chain lube, works for me. The TX200 is a bit front heavy, if you don't mind the extra weight you can usefully put a bit of lead in the back of the stock. It's a heavy rifle as standard, so beware this if you tire easily :blink: Quote Link to comment Share on other sites More sharing options...
