Grand Slam riflescopes compare to the best of the best at the sporting goods counter, except for the price tag. You'll find the cost of a Grand Slam is extremely reasonable for all the advanced features packed into it. Fully multi-coated lenses reduce glare and give you edge-to-edge clarity. They're outstanding in low-light situations. All Grand Slam scopes feature a fast-focus eyepiece adjustment ring, to let you adjust the scope perfectly to your eye. The "sure grip" power ring helps you find and adjust the variables, even with heavy hunting gloves on. Finally, Grand Slam's solid, one-piece construction helps make them waterproof, fogproof, and shockproof, so they'll last for years to come. The best for low-light situations. Superior optics combined with a huge 50mm objective lens gives you the brightest view possible in high or low light. -3.5-10x50 -Finish: Black Matte -Reticle: Duplex -Objective Diameter: 50 -Eye Relief: 3.4" -Length: 12.75" -Weight: 16.25 oz. -Field of View @ 100 Yards: 3.5X (29 ft.) 10X (11 ft.) *A portion of the proceeds from the sale of Grand Slam Riflescopes will be donated by the factory to the Rocky Mountain Elk Foundation.
