Unity Tactical FAST Optic Riser Aluminum Flat Dark Earth

The Unity Tactical FAST Optic Riser is a Picatinny-mounted riser that lifts a direct-to-rail red dot optic to a lower 1/3 co-witness height. It is built from anodized aluminum in a Flat Dark Earth finish and measures 3.6 inches overall. FAST mounts are designed to create an optical centerline about 2.26 inches above the rail, which the manufacturer describes as supporting a more natural heads-up sight picture.

The riser attaches to the rail with a two cross-bolt clamp. It is listed as compatible with the FASTQD Quick Detach Lever, which is sold separately. Compatible optics named in the product text include the EOTech EXPS and Vortex UH-1. For an absolute co-witness height optic, the retailer points to a different product, the FAST Absolute Riser.
