The US Optics Ring Level is easy to install and does what it is designed to do which is to make sure that your scope is level.

I shoot in 600 yard prone F Class Target-Rifle meets at various ranges where my bipod may not always rest on a smooth level and stable surface. The US Optics level gives me the confidence that my rifle is level prior to making every shot.

I made many comparisons and read reviews before deciding on this device. Although having the price quite high it is of fine quality and fit the bill for my needs. The ability to fold it out of the way is a big plus on protecting it from damage. Does a fine job on leveling the rifle.

The device is well made, and works just as you would expect. The swivel is worth the extra money because otherwise, unless the level is removed after shooting, it is only a matter of time until the fixed level is accidentally broken off. It is worth noting that the rail mounted level actually indicates whether or not the rail that is part of the rifle is level. A scope reticle still has to be adjusted to be perpendicular to the rail in order for the bubble to help align the rifle and scope. This isn't a big deal, as a properly mounted scope should end up that way, but unless the scope was mounted on a leveled rifle it won't happen.

Thought long and hard over getting this and now wish I had not waited. This has made a big improvement in disipline shooting, keeping the rifle level. This device helps when mounting the scope in the ring. I can tell when the chamber is level and set the reticile to the level. Highly recommend this product and Optics Planet for your supplier.

This may cost more than the other levels, but you get what you pay for. I moves out of the way and hides nicely under the scope until you need it for that long range shot.

This is a great anti-cant device that installs in about 30 seconds. It's really easy to get level with the rifle and once set, you're good to go. I placed my near the front of the scope as far forward it would go. I can easily read level at the same time acquire the target.
