Aim-O AIMO084 Base Mount 25.4 mm / 30 mm — Black

Anodised aluminium scope mount compatible with 25.4 mm and 30 mm tube optics, fitting standard Picatinny rails. The adapter insert included in the box lets you use the same mount with both diameters, with no additional parts to buy. It is a compact solution aimed at shooters who frequently swap optics or want to run multiple interchangeable setups.

The black anodised aluminium construction keeps overall weight at 210 g without compromising the structural rigidity needed to hold zero under recoil. Dual-diameter compatibility is convenient, but it involves a trade-off: the adapter insert adds an interface layer between the optic tube and the ring, which makes careful tightening of the clamping screws essential to eliminate any residual play — particularly on firearms with significant recoil. On low-recoil platforms or airsoft replicas the tolerance margin is wider, and configuration flexibility becomes the main advantage.

The compact profile suits both carbines with short handguards and platforms with limited clearance between the rail and the stock. The black finish integrates cleanly into most tactical and sporting configurations.

Key points

• Compatible with 25.4 mm and 30 mm tubes via the included insert, no extra purchases needed.
• Black anodised aluminium, 210 g, with solid rigidity under recoil.
• Mounts on standard Picatinny rail, found on the vast majority of modern platforms.
• Compact profile that does not raise the optical axis excessively above the iron sight line.
• The adapter insert requires precise screw torque to eliminate residual play and preserve zero.
