What Tune Up Spring Kit For Air Arms TX200 MKIII

I tried several different kits in mine from different suppliers, plus a Vortek sub 12 ft lb kit and then the Vortek PG2 SHO-Tune Kit fits Air Arms TX200 / Pro Sport Air Rifles. The PG2 SHO-Tune Kit provided by far the best accuracy in my TX 200. Surprisingly, its output is about 12.5 ft lbs with the AA 8.3 Gr pellet, which after testing nearly every diablo pellet made, shoots the best consistent groups in my AA TX200 MKIII.

The sub 12 ft lb kit was really sub in that it only produce about 9.5 to 10 lbs.

Good luck.

My tune done by John in PA was done with the Vortek sub kit and is shooting close to 12 ft/lbs so I am legal foe Field Target. No issues here.

Mr Maccari's kits are also wonderful and he has survived the "test of time".. Avoid any kit with a square cross section called OX spring.

Installed the Maccari spring /seal kit in mine. Very nice. 13.5 ftlbs

DZ,

A few years back Vortek sub kits were outfitted--by accident--with the wrong springs. My prosport got about 10fpe with that kit as well. Anyway, Vortek realized the error, so the new sub 12 kit is likely to be closer to 12 than 9.5 or 10. I experimented a lot with springs, and found that Maccari's 4600 spring (out of stock now, I think, but you might ask for a sub) with made-to-order tophats from Motorhead worked best. I'm shooting right at 12 now with a PS .22, and it's a delight. Can't really go wrong with Vortek either.
