Just got it today due in no small part to the CP strike. But the wait was worth it. This kit is amazing! It's by UK tuner Tony Leach. Goes by airguntech in FB if you want to get in touch. Also has a FB group, Lost Volume. Or by bigtoe in various forums.

So the gist of it is this is a 12fpe optimized kit. There is less swept volume as you don't need the original piston's full stroke for 12fpe. It's composed of a sleeved comp tube with a skirtless, severely lightened piston and the original 12fpe/UK spring has been reduced and redressed by one coil. As a result, you have reduced cocking effort, and extreme hold insensitivity due to less recoil from the lightened piston. You send your TX internals sans seal to Tony in the UK and in a few weeks you get your modded internals back. This conversion needs a 12fpe spring. If you have a 16fpe version, Tony can provide the 12fpe spring at cost. There's also the option of fitting his parts yourself if you're handy with airguns at a very significant discount.

Attached are pics in sequence:

1. The bottom parts are what goes into the rifle. The top parts are leftovers from the conversion. If you don't like it (can't see why you wouldn't unless you really want the power), the process is reversible. You just need to buy another OEM 12fpe spring.

2. A closer look at the piston. Roughly half the weight of the original.

3. Per Tony, applied a very light greasing using moly powder suspended in STP. He says it's the best lube he's ever found after a lot of experimentation. Better than straight up moly grease. Will have to compare this when next I strip my HW77 as that has just plain moly grease but so far with the TX, love it.

4. It could be the more powerful scope, could be the 22mm conversion, could be both. But I'm not an experienced shooter at all and this was a baby carrot at a lasered 48 yds on the first try.

5. Thinking that was just too easy, tried a banana stem at 48 yds. Similar result.

Now, I realize this is diminishing returns as the TX was a great springer out of the box. Pretty sure a stock TX will be just as accurate as any tuned version assuming you hold it the exact same way. Every. Single. Time. It's the same barrel after all. But of course that's a tough ask for anyone. If you wan't easy cocking and shooting, I definitely recommend this kit. Thanks for your time and best regards!
