Handle your short to medium distance shooting optic needs with the matte black VX-3i 3.5-10x40mm CDS Riflescope, featuring their Custom Dial System and Wind-Plex reticle. At the heart of the CDS is a customizable Bullet Drop Compensation elevation dial; just send your information to Leupold and you’ll receive a dial that’s custom-tailored to your individual loads. The Twilight Max Light Management System balances light wavelengths to give you the best possible sight picture even in the low-light conditions of dawn and dusk. To further improve contrast and reduce stray light, the eco-friendly, lead-free optical elements have their edges blackened. This scope offers 52 MOA of windage and elevation adjustment with a 1/4 MOA per click impact point correction to help compensate for wind drift and ballistic bullet drop. The Wind-Plex reticle has a series of hashes on the horizontal axis to compensate for wind deflection. It is located on the second focal plane, so it is unaffected by magnification. The easy turn power Selector makes changing magnification simple, even with gloves on. The 6061-T6 aluminum housing is lightweight and durable, waterproof, fogproof, and features a twin bias spring erector system that increases holding force. To prevent fogging-up of the optics when you are moving through environments with changing temperatures, the housing is filled with a mixture of krypton and argon gases. The rugged design is bolstered by the use of DiamondCoat protective lens coatings. Custom Dial System (CDS): Allows the buyer to contact Leupold and receive one custom BDC (bullet drop compensating) dial free of charge. Leupold will build a custom turret dial based on the ballistic information of the cartridge that the buyer intends to use with their firearm. The scope ships with completely functional stock turrets. The custom turret may be added later, if desired Actual magnification: 3.3-9.7x; Objective lens: 40mm diameter; Main tube diameter: 1″; Eye relief: 4.4 – 3.6″; Twilight Max Light Management system balances light wavelengths to optimize sight picture in low-light conditions; Blackened lens edges reduce unwanted glare and diffusion through the lens edges to provide better resolution, improved contrast BAS (Ballistic Aiming System) offers unique reticles to help estimate range and improve accuracy; 1/4 MOA per click impact point correction offers repeatability and dependability over a lifetime of use; Easy turn power selector with larger and brighter numbering; 52 MOA windage/elevation adjustment range; Twist parallax adjustment.
