Features of Vortex Razor HD Gen II 4.5-27x56mm Rifle Scope 34mm Tube First Focal Plane:
Optical Features:

• APO System: Index-matched lenses correct color across the entire visual spectrum.
• Optically Indexed Lenses Optimize image sharpness and brightness from edge to edge.
• 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. Features eleven intensity levels of illumination with off positions between each setting
