So, after waiting a while, I finally took the jump and installed a FX STX barrel in my Leshiy 2 this afternoon.
As background, I have a L2 in .25 cal and a 350mm barrel, with the Valkyrie handguard and Huma Mod40. This combination was shooting the JSB 25.4 grain pellets at 891 FPS, for 44.8 FPE. After reading a couple of threads regarding Cross Platform options for the L2, including the info from GlemChally and BigHUN above, I reached out to Geoff from Sub-12 Airguns on the UK and purchased three of his adapters for FX. Barrels to use in the L2. I have a number of FX barrels, including a Dreamline .25 cal 600mm barrel, and this was the one I chose to use for this experiment.
Basically, I had to remove the brass transfer port portion of the FX barrel and screw in the adapter. This was a hell of a lot harder than I expected, but heat, brute fore, and ignorance eventually overcame good sense and I got it off. From there it was easy to screw on the adapter, replace the FX liner and reassemble the barrel. It slid in to the L2 like they were made for each other!
All that was left was testing for accuracy and speed. At 25 yards the gun was every bit as, and maybe a bit more, accurate than the original. Essentiallly one hole with Air Arms (JSB) 25.4 grain pellets. One hole over 5 shots. On the FX Chrono it gave an average of 990 FPS or 55.3 Foot Pounds Energy. This is without any change to the regulator, just the barrel swap! I gained 100 FPS and 11 Ft Lbs of energy.
This is a real game changer for me, since I have a number of FX guns, not to mention barrels in every length and caliber from .177 to .30, and from 380mm to 700mm. Unlike a lot of people, I love the FX Smooth Twist liner system, and they have always been superbly accurate for me. Being able to use these in the L2 gives me immense flexibility at almost no extra cost, just the price of a magazine.
I love the looks, especially after I put a carbon fiber barrel sleeve over the barrel. I used the Huma Mod40, but it really is quite long, and probably overkill, so I switched to a FX hollow moderate. I actually think the longer barrel may even be a bit quieter.
