These high-tech scope rings give you the perfect interface between your scope and rifle with Barrett’s ZERO-GAP technology. Manufactured from 7075 aluminum alloy, they grip tight even under the heaviest recoil without adding unwanted weight. Barrett’s scope-clamping ZERO-GAP design allows you to simply tighten the cap on the indicated side until there is no gap between the lower ring and ring cap, check for perfect reticle alignment, tighten the other side and fire away.
