Well i am torn, the gun i shoot the most, and so i would argue also my favorite is the FX Maverick, but OMG i have lost count on how much grief it have given me, for starters pretty much the first 6 months i owned it, it was nothing but grief.
Not before i got the 700 mm barrel did the rifle perform as expected.
In hindsight i should have returned it to the seller.
My Vulcan 3, right out of the box been pretty much problem free, well aside for me attempting to do more than it or the ammo are able to handle, but 0 grief.
O and then my old FX Cyclone, it have always been good, just feed it some 15 or 18 gr .22 pellets and its good to go.
