Ruby is a very bright front bead in all lighting conditions. It allows you to aim easily with both eyes open. A remarkable and significant gain in visibility in weak light or against a dark background or a background with little contrast. Ideal for beginners or experienced shooters and hunters who will maintain constant focus while shooting. Available in Orange, Red or Green. Two models: 2.75in (recommended for Hunting) and 4.75in (recommended for Sports Shooting).
