Unity Tactical | F.A.S.T. Absolute Riser | FDE

The Unity Tactical F.A.S.T. Absolute Riser elevates block-type red dot optics to an absolute co-witness height with a 2.26″ optical centerline, promoting quicker reticle acquisition when wearing electronic hearing protection, night-vision devices, or protective masks. It provides an elevated M1913 Picatinny platform for direct attachment of optics such as EOTech XPS and Leupold LCO and is designed to pair with Unity’s FASTFTC magnifier mounts. The riser ships standard with a two cross-bolt rail clamp and retains compatibility with the FASTQD Quick Detach lever.
