Secure your 30mm optic to rifles with 11mm or 3/8" dovetail rails with this set of two 22 Type High Aluminum Riflescope Rings from Sun Optics USA. Each ring features a wrap-around design that reduces pressure on the scope's tube, along with four Torx cap screws and a flush-mount clamp screw on the base.

These rings looked sturdy out of the box and fit as expected. However, one of the threaded holes stripped with extreme ease (please note I did not put much force on any of these screws) and as a result I could not mount the scope as I wanted. Secondly, these rings were actually not high enough to fit a 50mm objective and be able to use the iron sights. I would send these back but it looks like the cost is not going to justify that action as from what I saw shipping is nearly half of the price.
