Thread: JW15 piece of shit

Yes trimming barrel is easy. Pop it into vice, measure 16" from receiver (or the length you want), cut off with hacksaw, tidy end with grinder or file/wet and dry etc, then put appropriate size round head brass screw in drill, and work into bore end with grinding/lapping paste to create new crown. Then check by putting cotton bud in and out of bore to ensure no burrs, perfect crown. Does it work - about 20 done and all but one sub 1" at 50m, and most around 0.4-0.5" groups.
