I always look for fit, form and function
at a resonable price. This rail is easy to mount, tight tolerance for scope mount. After alingnment removed and reinstalled Red/Green dot sight. The unit holds zero very well. Just remember to use loctite blue on the retention screws to keep it aligned. They will loosen up if you don't.
Pros: Price, ease of mounting, strong
