The Unity Tactical FAST QD Lever replaces the standard two-bolt rail clamp on compatible FAST mounts to introduce instantaneous, tool-less rifle integration. Co-developed alongside American Defense MFG (ADM), this throw lever allows operators to rapidly swap or strip optics in seconds under harsh operational conditions. It comes standard with an over-engineered, proprietary UNITY adjustment nut that must be utilized to maintain proper alignment and zero across Picatinny rails. Using a generic, standard ADM nut will lack the specialized profile needed for FAST housings, causing severe rail interface distortion that voids the factory warranty. Machined from rugged 7075-T6 aluminum and finished in a resilient Type III hardcoat anodized black, it delivers rock-solid retention capable of handling punishing environmental field abuse.
