Athlon Optics HELOS BTR GEN2 1-10×28 ATMR4 SFP IR MOA Reticle BLK, Second Focal Plane, Illuminated Reticle

Illuminated Reticle: The illuminated reticle provides greater visibility during dusk and dawn and other low ambient light environment.
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
Aircraft Grade Aluminum: The aircraft grade aluminum 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 the inertia gas with bigger size molecules to purge any moisture out of the tube giving you better waterproofing and thermal stability .
