DISCOVERY 30MM RING MOUNT BUBBLE LEVEL

The 30mm DISCOVERY RING MOUNTED BUBBLE LEVEL is an ideal tool for fine tuning scopes that have a 30mm tube. It comes with an allen key that makes it easy to mount onto your scope. This level ensures that your scope aim matches the trajectory of your rifle, and by canting the rifle slightly to any angle , it will lead to either shooting left or right or the chosen target. Once you have everything set and it matches the level of the rifle crosshairs, this level becomes irreplicable as a shooting aid.
