ENDURANCE - ENGINEERED TO LAST.
Hunting is serious business. If your optics haven’t been specifically designed with hunting in mind, can you trust them when the time comes to take the shot? The Endurance line of scopes feature chassis and reticle designs that have been explicitly engineered for everything from varmint to big game hunting. The Endurance Range is available in either a 30mm or 1 inch mono-tube chassis. The LER 1 inch model boast exceptional eye relief in excess of 4.5 inches, ensuring safety and mounting flexibility on even the highest recoiling firearms. The 30mm chassis is available in either a fixed 100 yard parallax or a side focus model. All 30mm models use a coil erector spring, maximizing internal stability.
