Warne Maxima makes these Fixed Scope Rings with Grooved Receiver to adjust to 1-inch high and in a matte finish. They are designed to provide your weapon with a solid base to attach your scope or other accessories to. The build and construction uses heavy-duty metal to maximize the strength and durability of the base. This added stability will help make sure you are better able to sight your weapon and spend less time realigning it after firing only a few rounds.
