I have had 4 FX rifles over the years, Mk1 and Mk2 Verminator, cutlass and cyclone. The early ones were light and compact, simple magazine system but a little fragile. My Mk1 verminator did need seals and broke a cocking lever after about 20,000 pellets and 4 years of use. the new ones are much more robust with the mk2 block on the verminator and the royales, but not as compact and more fiddly to load. Accuracy has been excellent on both the smooth twist and walther barrelled guns, but I think the walther barrelled full length cyclone I had was the best. I only own a verminator mk2 just now, I have handled the FX bullpup guns but don't really like them. I hope to get an FX crown when they come to the UK and I may buy a streamline if I can handle one at my local club and like it, but I have not seen one in the flesh yet.
