Weaver Grand Slam Riflescopes compare to the best of the best at the sporting goods counter - except for their price tag. All Weaver Grand Slam Scopes are equipped with the Micro-Trac 4 point adjustment system, the best in the industry. The fully multi-coated lenses of these Weaver Riflescopes reduce glare, increase image brightness and give you edge-to-edge clarity - they're outstanding in low-light situations. Weaver Grand Slam Rifle Scopes also feature a fast-focus eyepiece adjustment ring to adjust the scope perfectly to your eye. The Weaver "sure grip" power ring helps you find and adjust the Rife Scopes ' variables, even with heavy hunting gloves on. Finally, the Weaver Grand Slams are made with solid, one-piece construction, and sealed to be waterproof, fogproof, and shockproof - so they'll last for years to come.
