Gen 3 Flip-Up Front and Rear Sights Dark Earth – FMA

A pair of third-generation FMA flip-up sights, front and rear, made from polymer in Dark Earth. They fit 20 mm rails and stay folded beneath your main optic until needed: a side release flips them up in an instant as back-up sights when your red dot runs flat or gets damaged.

Shape and style

The profile follows the MBUS 3 style: a compact shape, protective wings around the front post and a well-shielded rear aperture. Dark Earth pairs well with tan replicas and gear, while the Biohazard logo adds a touch of character to the rear sight.

Mounting

Both sights clamp onto 20 mm rails, lined up along the top of the replica. Folded down, they sit low on the rail and leave a clear view through an optic mounted higher up; once raised, they adjust for elevation and windage to zero them.

In the field

A straightforward way to never lose your sight picture during long games and MilSim events: if the optic fails, just flip them up and keep playing. The polymer build keeps weight down at the front of the replica.
