First Focal Plane Reticle: | The first focal plane design allows you to fully utilize specially designed reticles that shrink or grow along with your target as you zoom in or out. These reticles offer quick target engagement at low power while offering precise holdover positions with finer details. |
Locking Turrets: | The locking feature on both elevation and windage turrets allows you to simply pull up the turrets to dial and push down the turrets to lock them in place. This feature gives you a peaceful mind whether you are moving from one station to next during your competition or putting them away for your next hunting trip. |
Illuminated Reticle: | The illuminated reticle provides greater visibility during dusk and dawn and other low ambient light environments. |
Etched Glass Reticle: | Reticle etched on the glass that provides excellent backing support for complex reticle design and offers great durability and much higher shock resistance to recoil |
Advanced Fully Multicoated: | Fully Multicoated optics effectively reduces reflected light and increases the transmission of light giving you a brighter image than normal single coated lenses |
6061 T6 Aluminum: | The 6061T6 aircraft grade aluminium tube that has exceptional strength and superior mechanical integrity will protect these world-class optics no matter what punishment you throw at it. |
Heat Treated One Piece Tube Construction: | Heat-treated one piece tube gives the scope extra strength over multi-piece tubes. A one-piece tube also is better at keeping moisture out thus keeping your scope fog proof for the life of the product |
Waterproof: | Waterproof to protect the scope in the harshest weather conditions or if accidentally submerged underwater |
Fog proof: | Fog proof to allow you to immediately engage your target when you take your rifle to cold ambient temperature from warm inside |
Shockproof: | Robust mechanical system with special designs on both control and erector system that give you the ultimate recoil resistance to withstand 1000G recoil for 1000 times. |
Argon Purged: | Argon Purging uses inertia gas with bigger size molecules to purge any moisture out of the tube giving you better waterproofing and thermal stability. |
