Flip-up fiber optic sight set Picatinny rail DOUBLE BELL

The DOUBLE BELL flip-up fiber optic Picatinny rail sight set is a compact backup solution designed for airsoft replicas equipped with a Picatinny rail. Its main differentiating feature lies in the combination of two fiber optic inserts, red on the front sight and green on the rear sight, which improve sight picture readability in low-light conditions.

Made from polymer for a reduced weight, this set integrates a spring-loaded flip-up mechanism activated by a push button, allowing instant deployment without cumbersome manipulation. The folding design clears the primary optic's line of sight when not in use, and mounting is done directly onto any standard Picatinny rail. A practical and reliable accessory for a mechanical backup sight that is ready to use in any situation.
