Unlike traditional scope rings which require careful attention be paid to maintaining equal gap between the upper and lower ring halves, Barrett’s ZERO-GAP technology eliminates this tedious process. Simply tighten the cap on the indicated side, verify reticule alignment, tighten the remaining side, and fire away. The end result is a perfect fit between scope and mount that will withstand even the heaviest recoiling rifles. Machined from 7075-T5 aluminum and with MIL-SPEC Type III anodized finish, ZERO-GAP Rings are available in a variety of heights for both 30mm, 34mm, and 35mm optics. Simplicity at its finest.

HOLDING AREA
Barrett ZERO-GAP Rings are wider than typical rings at 1.2 inches. This creates a greater surface area of contact between the ring and scope maintube. The benefit is a secure grip on the optic that will hold up under heavy recoil. Along with this solid connection comes protection for your expensive scope. The broad clamping area spreads out the forces and reduces the likelihood of denting or distorting the scope tube. The same benefits in scope holding translate directly to the mount's ability to hold on the rail. More width in rail clamping area is better.

HEAVY DUTY HARDWARE
The rail clamping cross bolt and nut are precision machined from hardened steel alloys. The cross bolt is securely pressed into the scope ring base, and the end of the bolt is staked to retain the nut. The cross bolt is designed with a broad shoulder to perfectly interface with cross slots of mil spec 1913 rail to resist even the harshest recoil. The top cap of each ring is retained by four robust Torx screws placed with broad spacing to provide consistent and evenly distributed clamping force.

PRECISION AND TOLERANCE

All critical features on Barrett ZERO-GAP Rings are machined with great care. The 30-mm bore will be exactly that with a diameter tolerance of plus or minus .001", perfect roundness and position in relation to the mounting rail. Angles and surfaces in the rail clamping feature of the lower ring are held to great positional tolerances to ensure the scope is held centered when bolted up to the rail.

FIT AND FINISH
Every component of Barrett ZERO-GAP Rings is carefully handled all the way to packaging. All edges are beautifully rounded to prevent snags and resist corner wear. The 7075 T-6 components are hard anodize coated in black to mil spec MIL-A-8625 Type III Class 2 specification for superior surface hardness (60 Rockwell) and resistance to wear. Steel components are manganese phosphate coated to mil spec DOD-P-16232 Type M Class 2 specification.

ZERO-GAP® DESIGN

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.
