Barrett® ExRings with Pin-Lock technology is a dual-setting MOA extended range ring set that maximizes the use of

riflescope’s precise internal elevation adjustment by aligning the scope for long range shooting. Barrett’s ZERO-GAP

technology provides definitive holding power for heavy scopes under the harshest recoil.

Purpose:

To maximize use of the riflescope’s precise internal elevation adjustment by angling the scope without

compromising the rigidity of a one piece mount.

Fit and Function:

Works on flat and tapered M1913 rails with riflescopes having up to a 70mm objective lens. Choose either 15/40 MOA

or 20/30 MOA taper by simply removing the rear pin from one hole and inserting it into the other.

Key Features:

• ZERO-GAP offers wider clamping area and maximizes “scope grip”

• Fits M1913 rails

• Maximizes the riflescope’s internal elevation adjustment for long range shooting

• ZERO BACKLASH tongue and groove interface

• High Strength Aircraft grade 7075 T6 aluminum construction

• 2.5x lighter than steel

• Heat treated steel cross bolt and captured nut for increased strength

• Hard Anodized with a 60 HRC (Rockwell C scale)

• BORS compatible

WARNING: TO AVOID INJURY CAUSED BY RECOIL, FOLLOW YOUR SCOPE MANUFACTURER’S MOUNTING

RECOMMENDATION FOR OBTAINING A SAFE EYE RELIEF DISTANCE.

Note: Successful long range shooting requires that the scope reticle be level. Scopes canted even slightly will result in

significant errors at long distances.

Barrett rings are designed for use on M1913 rails. Most rings are designed so the caps are tightened evenly on both

sides. Barrett rings are designed with ZERO-GAP technology with wider clamping that maximizes scope grip. Two cap

screws are fully tightened on the index marked side of the ring before tightening

the opposite side cap screws. The ZERO-GAP feature is designed into the lower

ring halves alone so the Barrett logo on the ring cap can face in either direction.

Note: Ensure that the-step cut side of the clamp rests on the ring and not the rail.

The index marked ZERO-GAP side of the ring is on the side with the clamp nut.

the ring bases.

. Loosen the clamp tightening nuts on both lower ring cross bolts. 3. Using the T27 Torx® end of the supplied L-wrench, loosen the four 10-32 side bolts to allow rings to pivot slightly while installing scope, to eliminate binding. 4. Taking into consideration your scope dimensions and estimated eye relief, position the rear scope ring in the appropriate rail slot and place the front scope ring nine slots forward of that position. Tighten the clamp nuts to 65 inch/lbs or 7.34 Nm. 5.
