To endure the toughest battlefield conditions, the 34mm maintube is machined from a single piece of aluminum, and provides a waterproof and fogproof performance. The windage and elevation knobs are knurled for slip-free operation and offer 72 MOA adjustment ranges with 1/4 MOA increments. Also available with this riflescope is the Sig Ballistic Turret Dial (SBT), which features precision tactical finger-operated knob with a fine diamond knurling and a slit read-out facing the ocular. The Sig Ballistic Turret (SBT) is a custom laser-etched elevation dial that uses your bullet specifications, ballistic coefficient, muzzle velocity, elevation, and other environmental factors for the correct bullet drop compensation, and pinpoint accuracy. All other dials and rings are also enhanced with a fine diamond knurling for a slip-free grip, including a side focus parallax corrector and a fast focus eyepiece. The eyepiece has a low-profile zoom lever with a bright green mark for visibility.
