This is a set of every 30mm Ring that Barrett makes, including the accessory cap, for shooters who may have many different optics and rifles to set up, or like to keep extra stock.
Barrett rings are the best, toughest, and easiest to install rings available. The Barrett ZERO-GAP system ensures the easiest, and most reliable scope mount possible, without any added headaches, and the Pin-Lock system allows you to select from two mount angles.
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.
ExRings with Pin-Lock and ZERO-GAP technology have a dual setting MOA taper at 15 or 40 MOA, utilizing the riflescope’s precise internal elevation adjustment by aligning the scope for long-range shooting. The front ring assembly is designed with a precision fit pivot that allows the scope to elevate in the rear, but tolerances ensure no unwanted movement. The rear ring assembly houses the Barrett Pin-Lock technology that allows the user to select from two MOA settings. Once an MOA setting is selected and the ring’s four cross bolts are torqued to specification, Barrett ExRings become a rock-solid mountwith the correct taper to maximize the potential of your rifle system
