Barrett ZERO-GAP 30mm High Scope Rings Picatinny Mount Aluminum Black

Barrett rings are the best toughest and easiest to install rings available. The Barret ZERO-GAP system ensures the easiest and most reliable scope mount possible without any added headaches. The unique scope clamping design of Barrett ZERO-GAP Rings takes care of some old optics mounting challenges. In the past great attention was required when securing scope ring caps to maintain an equal gap between the lower ring and top cap on each side. There was also the possibility of rotating the scope out of perfect vertical reticle alignment while torquing the cap screws in a side-to-side pattern. These problems are eliminated with the ZERO-GAP design. Simply secure the cap on the indicated side until there is no gap between lower ring and cap check for perfect reticle alignment and then torque the remaining side to the required specification. Zero-Gap rings are available in four heights to fit any rifle/optic configuration.
