Redfield's Widefield scopes offer a field of view that is 30% wider than conventional scopes, nearly 40 feet wide at 100 yards. The Widefields are also designed to mount low on the receiver so you get a quicker sight picture when you shoulder the rifle. Widefields are also waterproof, fogproof and shockproof and offer fully multi-coated lenses for a sharp clear sight picture. Covered under Redfield's Limited Lifetime Warranty.
