Aim-O 45° Offset Mount for RD-1 / RD-2 — Black

The Aim-O 45° offset mount is designed to attach the RD-1 and RD-2 red dots to a 20 mm Picatinny rail, letting the shooter transition instantly from the primary optic to the red dot by rolling the rifle onto its side. It is the go-to solution for shooters running a scope or prism optic for mid-range work who need a secondary aiming system ready for close-quarters engagements without taking their hands off the rifle.

The 45° canted mounting position keeps the red dot off the primary optical axis: when shooting from a normal stance the red dot stays out of the field of view and causes no interference, but a simple roll to the right brings the dot in line with the target at short range. This trade-off is the core of the offset concept: it adds versatility without meaningful weight gain or changes to the primary setup, but it does require the shooter to have the roll motion well ingrained — otherwise the transition is slower than a dedicated secondary system would be.

Compatibility is specific to the Aim-O RD-1 and RD-2 models, which mount directly to this bracket without any additional adapters. The standard 20 mm Picatinny rail interface ensures compatibility with the vast majority of AR platforms, bolt-action rifles fitted with a side rail, and tactical carbines.

Key points

• The 45° angle allows transition to the secondary optic with a simple rifle roll, no change of grip required.
• Compatible with 20 mm Picatinny rail: fits the side rails of almost all modern tactical platforms.
• Designed specifically for the Aim-O RD-1 and RD-2 red dots, providing a precise fit with no play.
• Keeps the primary optic zeroed on the bore axis without visual interference during normal use.
• Low-profile configuration: the red dot stays clear of the primary optic's field of view until needed.
