I'm another recent proud owner of a JW-20. I love this rifle. My takedown latch was a pain too but after a few minutes with a file it's nearly perfect. I feel like I might need to ream the hole in the stock a bit too; loading rounds got hung up unless the gun was held at a steep angle. Aside from the finicky things, this gun is fun to shoot and I can see it easily becoming a favourite. If only I could track down the scope base though...
