If you're serious about long-range shooting, you'll be comfortable with the Hawke Sport Optics 6-24x56 Vantage 30 SF2020 Riflescope mounted on your rifle. The zoom range is designed to give you a good look at targets far downrange. Low-dispersion crown glass with 18 layers of anti-reflection lens coatings admit generous amounts of light for a bright, high-contrast sight picture. The high-intensity, multi-LED red 20x Half Mil reticle offers six brightness levels with off positions in between. The zoom ring is heavily knurled for sure and swift magnification adjustments, and comes with a removable throw lever for even more speed. The 4" eye relief will protect you from recoil when using high-caliber rounds.

The exposed locking turrets adjust impact point at 1/10 MRAD per click with a total range of 20 MRAD for elevation and windage. Complementing the performance of the scope is a lightweight and durable aluminum housing, with a robust 30mm one-piece maintube that is nitrogen filled and O-ring sealed to be water and fogproof. A 4" screw-on sun shade is included to reduce glare and increase image quality and a 4" removable side adjustment wheel can be installed on the parallax turret for precise adjustments and ranging.

  Q: 9. Can the clamp be removed from the ball stem? I may want to change to a lever-release clamp, as offered by Really Right Stuff. It appears the K40 clamp can be unscrewed, but can't tell about the K30 or K20.

  A: It can definitely be removed, because I own this ballhead and have removed the clamp. But you will need to heat the screw with a small propane torch or even a soldering pen. The screw has been fastened using a loctite style adhesive which will require a fair amount of heat to undo.
