Ive got a FX typhoon in .177, lovely gun, accurate, feels good to the shoulder, seems well built and solid. my only gripe with it is that i believe that you have to remove the action from the stock to adjust the trigger. I had never heard of FX airguns either, and went into the shop looking for a .22 multishot pcp rifle like a bsa scorpion t10 or the like, and came out with a .177 single shot
Saw the FX on the rack and asked about it, liked the feel of it so took it to the range, hit everything that i pointed it at every time.
The bolt action on typhoon doesnt seem flimsy in the slightes
