Waterproof O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments.
Fogproof Nitrogen gas purging prevents internal fogging over a wide range of temperatures.
Shockproof Rugged construction withstands recoil and impact.
Hard Anodized Finish Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position.
