Description
A fixed 4x32 ACOG riflescope with a tritium and fibre optic illuminated red chevron BDC reticle for .223 / 5.56 flattop rifles, for professional and duty users.
This ACOG riflescope combines 4x magnification with a 32mm objective and a red chevron reticle with bullet drop compensation calibrated for .223 / 5.56.
The reticle uses dual illumination: fibre optics provide daylight illumination and tritium illuminates the reticle at night.
It comes on a Flattop Thumbscrew Mount (TA51) in an OD Green finish, with a forged aluminium housing.
Key features
- Chevron ranging reticle — The chevron is zeroed using its tip at 100 metres, and its base width of 5.53 MOA (19 in. at 300 metres) allows range estimation on silhouette targets.
- Calibrated BDC — The ranging reticle is calibrated for 5.56 (.223 cal) flattop rifles out to 800 metres.
- Automatic brightness — The tritium and fibre optic illuminated reticle adjusts its brightness automatically to the available light.
- Both eyes open — The Bindon Aiming Concept (BAC) supports shooting with both eyes open for improved situational awareness.
- Fixed-power design — The fixed-power design keeps moving parts to a minimum for a rugged, reliable sighting system.
- Multi-coated lenses — Multi-coated lenses maximise light gathering and give a clear field of view.
- Waterproof, nitrogen-filled — The dry nitrogen-filled housing mitigates fogging and is rated to a submersion depth of -20m.
- Shock-resistant — The scope is proven to withstand recoil from a .22LR to a .50BMG.
Typical applications
- Duty and patrol rifles in .223 / 5.56 that need a fast, fixed-power magnified optic.
- Engaging and ranging silhouette targets at extended distances with bullet drop holds.
- Use in changing light, from daylight to night, without adjusting the reticle brightness.
