Description
A fixed 4x32 ACOG riflescope with a dual-illuminated red crosshair reticle calibrated for .223 / 5.56, for professional users who need a robust magnified optic.
This ACOG combines 4x magnification with a 32mm objective and a red crosshair reticle with bullet drop compensation calibrated for .223 / 5.56.
The reticle is illuminated by fibre optics and tritium, giving a bright aiming point in any light condition, and the ranging reticle allows bullet drop compensation out to 600 metres without any manual adjustments.
It is supplied on a flattop thumbscrew mount in a forged aluminium housing with a matte black finish.
Key features
- Dual illumination — The tritium and fibre optic reticle automatically adjusts its brightness to the available light.
- Ranging BDC reticle — The bullet drop compensating, target-ranging reticle gives holds out to 600 metres without adjusting the turrets.
- Both eyes open — The Bindon Aiming Concept (BAC) supports shooting with both eyes open for improved situational awareness.
- Fixed-power design — The fixed-power layout keeps moving parts to a minimum for a robust sighting system.
- Multi-coated glass — Multi-coated lenses maximise light gathering and give a clear field of view.
- Shock-resistant — The optic is proven to withstand recoil from a .22LR to a .50BMG.
- Nitrogen-filled, waterproof — The dry nitrogen-filled housing mitigates fogging and is waterproof to a submersion depth of -20m.
Typical applications
- Magnified sighting on .223 / 5.56 rifles for professional users.
- Rapid target engagement in changing light, from daylight to low light.
- Ranging and holdover at extended distances without adjusting the optic.
