Tuning Best Tune up kit for TX200HC?

It’s already very accurate ,what you want to do is minimize recoil but keeping some sort of fps. 

Usually people with these rifles take the power down because of the cocking effort. Some TXs come from stock with power shims ,maybe try going with a smaller top hat. and try and some tar lube to keep the spring noise down . Shoot and see if you like the feeling. Minimize a shim here and there……..

Some people go straight to the aftermarket kit. and realize they don’t like the 12ish lower fpe. those rifles are fun/easy to work on , Research ask questions then you can figure out how you wanna do (you’re) rifle.


 
I don't know if it's the "best" or not, but I'm very happy with the full power Vortek PG4 kit I installed in my TX200. It took all the vibration and buzz out of the shot cycle, just kind of a solid whack now. It did lose some speed over the factory spring, the improved shot cycle and accuracy makes up for it though.



Which PG4 did you get? The HO version?


 
I have never used a kit, always used factory parts unless a faulty part needed replacing. My current MK3 has all factory parts, just cleaned, lubed, spring ends polished, shims to fine tune the firing cycle. Mine shoots 8.4 gn AA pellets at 900 fps and will group with the best!! Very little recoil, no buzz, extremely consistant, kits can make for a quick and easy tune but your actual performance and accuracy will be no different than a tune with factory parts as long as they are in good condition. Unless you looking to make a big change like dropping down or going up in power
