Long-range shooters often encounter a common problem: Certain scope/rifle combinations don’t offer enough ‘up’ elevation adjustment in their scopes to allow the shooter to hit targets at the maximum range of their rifle systems. Dual MOA Barrett ExRings with Pin-Lock technology makes this issue a thing of the past.

With dual MOA settings, ExRings allow maximum use of the riflescope’s precise internal elevation adjustment by aligning the scope for long-range shooting. The front ring has a precision-fit pivot feature that allows the rear of the scope to be elevated at the rear ring with no chance of unwanted movement. The rear ring houses the Barrett Pin-Lock technology that allows you to select from two elevation settings by simply changing the location of a single pin.

Once an elevation setting is selected and the ring’s cross bolts are torqued to specification, Barrett ExRings become a rock-solid mount with the perfect MoA elevation for your particular long-range rifle setup. Barrett rings are made from high-strength 7075 T6 aluminum for long-term durability.

Last, but not least, ExRings also incorporate Barrett’s ZERO-GAP technology to give you 360 degrees of heavy-duty holding power under even the harshest recoil.

ExRings work on flat and tapered M1913 optics rails with riflescopes having up to a 70 mm objective lens. Adjust between 15 MOA and 40 MOA or 20 MOA and 30 MOA taper. Available in 30 mm and 34 mm.

One robust set of rings. Nice machining and good fit. Worth the price.

These rings are just what was hoping for, used on a Nightforce ATACR scope.
