It's not about the size, ok? The S.M.A.L. is for those mounting situations where you need a compact mounting footprint on the bottom of a rangefinder, binos, spotter, SBR, etc. With MLOK mounting points (and hardware) and a center 1/4-20 mounting point (again, hardware included) this will be a versatile mounting point for those items that don't need a longer rail. This item is milled, in America, from 6061-T6 aluminum and black hardcoat anodized. Mfg: Area 419
