tape mostly starts to fall off, leaving sticky messes.. ok on a 20 quid scope but on a 300 plus nooooooooo way!!
get a couple three or four scrib nets one over the gun, cut the rest up and thread them through, fat bits on the out sides of the cut ups, thin bit in the middle, pull a strip through the gun cover bit untill its on the thin bit.. hey presto... save the edging for tying on.
