Bad accuracy with my Marushin K98
 

Im usially good with these sort of things but its my first airsoft gun so i thought i would see if anyone else had this problem before trying anything else.

The Iron sight near the end of the barrel is always loose so i tried to tighten it but the screw went into the barrel and now it has a kink in it so the about 30% of the time the bb hits the kink and goes way off target, i tried shooting the gun while it was clamped down and the accuracy is horrible even after i tried to bore the end of the barrel.

anyway do i need a new barrel or did anyone else solve a similar problem before?

how much of the inner barrel is left after the kink? you could always cut the barrel at the kink providing the length you cut off isnt being held in place by the outer barrel,,a butcher type solution at best. or,,you could use this as an opportunity to upgrade to a tightbore barrel.

Check the hopup. I know for a fact on the marushin garand, if you dont have it set properly the bbs will go all over the place.
