UTG BullDot Compact Green Laser Sight Picatinny Weaver Rail Mount SCP-LS289S. The UTG BullDot (SCP-LS289S) is a sub-compact green laser sight built around a full aluminum body and a direct-mount Picatinny/Weaver clamp. The green dot measures 8 inches in diameter at 50 yards. Windage and elevation adjustments are both user-accessible without tools, letting you zero the unit to your rail position without sending it out or removing other accessories. Green Laser Dot – Green light sits near the peak sensitivity of human daylight vision (555 nm), which is why a green dot reads as brighter than a same-power red dot under ambient light. 8-Inch Dot at 50 Yards – The precisely sized dot provides a practical aiming reference without obscuring your target, giving you confidence in shot placement at real-world distances. Aluminum Construction – A full aluminum body keeps the unit lightweight while providing the rigidity and durability needed to hold zero under recoil and field conditions. Picatinny and Weaver Compatibility – The integrated clamp seats on both MIL-STD-1913 Picatinny and commercial Weaver rails without shims or adapters, locking down with a single cross-bolt. Windage and Elevation Adjustment – Both axes are adjustable via external set screws, giving you enough travel to zero the dot regardless of where along the rail the unit is clamped. Sub-Compact Footprint – The small body occupies minimal rail real estate, leaving room for lights or other rail-mounted accessories forward or rearward of the unit. Picatinny Rail, Weaver Rail.
