Nice gun. I love them. Very close to a real Hawken in appearance.
A few things.
Sometimes the wedges need to be fitted. Don't forget they are different sizes. I believe the long one goes in the rear.
You usually need to file down the front sight.
It usually takes 100 rounds to break in the barrel, or the JB will help for sure.
Enjoy, and give it time. They are good shooters.
