Operation and adjustment of the FAST™ FTC 4X magnifier’s integrated quick detach lever.
The FAST™ FTC 4X is the first integrated magnifier available on the market, bringing the magnifier up to a 2.26″ optical centerline from the rail. Integrating the mount with the optic shaves weight, increases strength and ensures streamlined functionality with near-zero occlusion of the primary optic when stowed.
