HD Lens Elements: Premium extra-low dispersion glass delivers the ultimate in resolution and color fidelity, resulting in high-definition images. XR Plus Fully Multi-Coated: Ultimate anti-reflective coatings on all air-to-glass surfaces provide maximum light transmission for peak clarity and the pinnacle of low-light performance. Plasma Tech: Cutting edge coating application process provides unparalleled coating durability and performance First Focal Plane Reticle: Scale of reticle remains in proportion to the zoomed image. Constant subtensions allow accurate holdover and ranging at all magnifications. Glass-Etched Reticle: Allows for intricate reticle design. Protected between two layers of glass for optimum durability and reliability. Illuminated Reticle: Provides precise aiming under low-light conditions Consrtuction Features: Tube Size: 34 mm diameter provides maximized internal adjustment and strength. Single-Piece Tube Maximizes alignment for improved accuracy and optimum visual performance, as well as ensures strength and waterproofness. Aircraft-Grade Aluminum: Constructed from a solid block of aircraft-grade aluminum for strength and rigidity. Waterproof: O-ring seals prevent moisture, dust and debris from penetrating for reliable performance in all environments. Fogproof: Argon gas purging prevents internal fogging over a wide range of temperatures. Shockproof Rugged construction withstands recoil and impact. Hard Anodized Stealth Shadow Finish: Highly durable hard-coat anodization provides a low-glare matte surface and helps camouflage the shooter's position. ArmorTek: Ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt. L-Tec Turrets: Integrated locking mechanism prevents accidental adjustments. Turrets provide fast, accurate, easily read elevation and windage adjustments. Patent pending. External Rotation Indicator: Provides quick visual and tactile reference of elevation turret’s rotational position. Locking Illumination: Locks illumination at preferred setting. Side Focus: Adjustment located on left side of turret housing is easily accessible from shooting position. Provides optimal image focus and parallax removal. Internal Mechanism Design Features: L-Tec: Zero Stop Prevents elevation turret from dialing below sight in range using rugged steel components. Internal mechanisms stay free of sand, dirt, dust, moisture and other foreign materials—even when setting the zero-stop position. Maximized Turret Zero Adjustment: Turret design allows expanded adjustment range when L-Tec zero stop feature is disengaged for zeroing purposes. Micro Adjust Zero Setting: Infinite zero setting positions allow zero to be set between clicks for optimal accuracy. Friction Reduction System: Heat-treated, hardened-steel pad floats on turret screw’s end, linking with hardened steel ring on erector tube for steel-on-steel contact. Prevents galling or deformation of contact point for superb durability and repeatability. Turret Screws: Provides low-friction, wear-resistant performance: precision-machined from a silicon-brass alloy and treated with an advanced dry-film lubricant. Turret screw threads are precision machined to sub-2 micron tolerances (less than 78-millionths of an inch). Erector Tube System: Precision-machined from aircraft grade aluminum with anti-galling properties for a lighter weight, strong, durable tube. Stainless Steel offset coil spring erector biasing system withstands much higher stresses than traditional flat erector springs Convenience Features: Fast Focus: Eyepiece Allows quick and easy reticle focusing. Locking Side Illumination: Easily accessible and lockable illumination dial is located on the left side of turret housing.
