Things I liked:Description said that it would fit a 11mm dovetail but it doesn't fit my AA TX200. Even if I managed to pry the clamps apart to fit, the "weaver rail" is too small for my Warne weaver scope rings. Even the cheap $9.99 UTG rail worked. That being said, it does look sturdy and well made. Things I would have changed:Add instructions. Make it a true "weaver rail" What others should know:I can't speak for other air rifles but avoid for your AA TX200.
Things I liked:Beautiful stock. Screams of quality through and through. Extremely accurate. Once you fire it a few times, you know where your money went. Things I would have changed:Make sure that you pull the charging handle all the way back until the safety pin engages. If there is tension in the charging lever, you did not properly charge the rifle. What others should know:Work on your left arm strength to support the rifle in an unrest firing position.
