The American Defense AD-B2 Cantilever Mini ACOG mount in the Night Vision height sets the optic at a 2.33-inch centerline (brand part no. AD-B2-NV-STD). It is built on a 0.75-inch reverse cantilever that moves a Mini ACOG or similar compact scope rearward, which solves the eye relief problem those optics have on an AR. American Defense machines it from 6061-T6 aluminum with a hard coat anodized finish and the patented QD Auto Lock lever. The maker lists the EOTech Vudu 3×9, Trijicon Mini ACOG (TA33, TA44), Sightmark Wraith Mini and Primary Arms GLx 2x and SLx 1x/3x scopes as fits. Pick the height that matches your cheek weld and rear sight: this one is the night vision option.

Key Specifications

• Centerline height is 2.33 inches, the Night Vision position in the AD-B2 line.
• The rise above the rail is 1.38 inch, which is what raises the optic to this centerline.
• A 0.75-inch reverse cantilever lets the optic sit farther rearward, which fixes the eye relief problem common to Mini ACOG-style scopes.
• Listed fits include the EOTech Vudu 3×9, Trijicon Mini ACOG (TA33, TA44), Sightmark Wraith Mini and Primary Arms GLx 2x and SLx 1x/3x micro prism scopes.
• The B2-NV is tall enough to clear back-up iron sights, a clearance the maker states for the B2-M and every taller AD-B2 height.
• The mount is CNC machined from 6061-T6 aluminum, a strong, light alloy suited to a rail mount.
• The patented QD Auto Lock lever works on both in-spec and out-of-spec Picatinny rails, with no proprietary tools required.
