Norinco KL-3B .177 Caliber Air Rifles reviews: "Another area of the KL-3B that, for the most part, gets ignored is its lack of a crown on the barrel. It comes with a 'pseudo' target crown but is merely a counterbore and does require some chamfering to improve accuracy. I used a small ball-bearing that I soldered to the head of a socket head cap screw, chucked that into a handdrill and used a fine grit grinding compound (400 grit Clover compound) to rework the muzzle end. You only need to 'break' the sharp edge by about .020' or so then do a bluing retouch on that polished surface.
