420585 Burris Signature Ring Features:

• Prevent "Ring Marks" On The Finish Of The Rifle Scope Tube By using precision-made, tight-gripping inserts made of a dimensionally-stable synthetic material, the riflescope is not scratched or crushed which often occurs with conventional rings
• Grip The Scope Better Burris Concentric synthetic inserts gripping the rifle scope tube are made of a material slightly softer than the hard-coat anodized rifle-scope tube
• Permit The Scope To Be Mounted Without Stressing The Scope Burris self-aligning synthetic inserts pivot within the ring housings to eliminate any axial misalignment and induced stress on the riflescope. Hunters and competitive shooters alike can experience temperatures from 10 degrees to over 100 degrees, and at even greater extremes. As an aluminum rifle scope and steel firearm expand and contract with temperature changes, the rifle-scope will maintain point-of-impact integrity much better if it is mounted stress-free
