Speaking of CFX muzzlebrakes, and not wanting to hijack anyone's thread I have a question. My new CFX .22 shoots a little lower than I figure it should be shooting. I've run out of room on the rear sight, the elevation knurl knob is too loose its up so high. I'm shooting at about 50~75 yards out, and all pellets are landing low. Crosman Premiers, Beeman Lasers, RWS Hobby, and of course kodiaks drop like a rock and I know hobbies are for short range. Don't have any superdomes yet, but I ordered some. I may be at the end of the useful range of the CFX.
Anyway, my question(s): is the front sight position affected by the allen screw that is on top of the muzzlebrake? Any way to affect front sight height?
