Inspired by the best sniper scope BEAST, I made this ring with a similar rifling to the adjustment turrets rings of this scope. As a musician tunes a musical instrument to produce a clear sound, so a sniper adjusts his scope for an accurate hit. A perfect gift for the military, police, special forces and all gun lovers. The truth is in the details that you can touch. Dimensions: 8 mm band width, 2 mm band thickness approx. Material: 925 solid sterling silver.
