My HW100 is from 2004....I've had or shot all manner of nice PCPs over the years and this old turd still has the best trigger and magazine system I've ever used. Not a powerhouse, and not the highest shot count, but they were way ahead of their time and still great guns.
This is a rebadged FX Tarantula in .22 from around 2002-2004. Very accurate LW barrel, and a very efficient and well setup unregulated action. These things are deadly accurate and nice and lightweight. Decent trigger and a reliable (although slightly cheesy) magazine system. Killer shooting guns. Most had a lot nicer grade of walnut than mine does, and some were downright stellar.
Another nice classic is the FX Cyclone. I had one that was rebadged as a Webley. It had a nice LW barrel, well tuned unregulated valve, simple 3 stage power adjuster, slick sidelever action and a removable airtube. Very lightweight, powerful, and frugal on air. They were available with a terrible synthetic stock with foam inserts that fell off, or a really nice walnut stock. I miss mine!
If you know me, you must know how hard it is for me to say this, but:
In the early 2000s before the HW100 came out, FX really made some killer sporting guns. Lots were rebranded as RWS, ARS, Webley....
