First, the thing is a Chinese copy of a ZKM451 (Brno model 1), but don't expect anywhere near the finished machining of the original Brno. The little JW is has a finish that fits the price

Step One. Clean off all the preserving oil gunk they drown the gun in. You may as well completely disassemble it to do this as the sweat shop workers who assemble these things aren't the best at it. Mine had the scope arse about and the action screws where half tight, While your at it, throw the scope in the bin as it's next to useless.. more on that later.
Anyway, first 50 shots I put through the rifle, as it came from the ship, it sprayed out like after a night on the curry. I put most of this down to the $2 optics and couldn't even manage a 4" group at 10 yards.. seriously, it was that bad.
So next day I completely pulled the rifle apart, took to the stock with a sharp chisel and hacked away like a lunatic until the barrel was fully floated. After re-assembly, I made sure all screws were tight, like real tight.
One thing you need to do to properly mount a scope is loose the iron sights. These things have a small length of pull and if you mount a reasonable length variable scope it bangs up against the rear tang and you can't get it forward enough to get proper eye relief to shoot prone.
Anyways, grease removed, iron sights gone tata, barrel floated, assembled properly and my spare Nikko GC 3-9x40mm mounted. This is what it looks like now. Hows it shoot? Check the next page
