The ARM52-43 adapter is designed to mechanically couple day optics to clip-on night vision or thermal devices. It provides the mechanical interface required to attach a clip-on unit to the objective tube of a scope, maintaining alignment for combined use.

Key features
Thread M52x0.75; declared diameter 43 mm; conventional ARM52 system with quick-release Q-R mounting; weight 0.164 kg. It is intended to join the clip-on mount to the scope tube using the M52x0.75 thread.

Compatibility
Compatible with scopes and accessories that use an M52x0.75 thread and have an outer fit appropriate for a 43 mm adapter. It is not compatible with devices using different thread standards or with mounts requiring a different adapter system.

Purchase check
Verify that the objective tube or accessory has an M52x0.75 thread and that the physical fit matches 43 mm to avoid mounting incompatibilities.
