Vortex Crossfire II 4-12x50 AO Riflescope (Dead-Hold BDC MOA Reticle)

Vortex Optics riflescopes boast extreme durability, high mechanical precision, and superior high-definition optics. The Crossfire II 4-12x50 AO Riflescope was carefully crafted and meticulously designed to make this rifle scope the ideal optical solution for long range tactical applications. The Crossfire II 4-12x50 AO Riflescope (Dead-Hold BDC MOA Reticle) brings you exceptional image quality thanks to the optical glass. The 50mm objective lens features a BDC reticle that offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing.

Superior Optics

Crossfire II 4-12x50 AO Riflescope lenses are fully multi-coated with anti-reflection coatings for maximum light transmission and minimum glare on all air-to-glass surfaces. The lens provides higher color contrast, sharper images, and superior light transmission. The glass-etched reticle was precision etched in the second focal plane for an image that always maintains the same ideally-sized appearance. It designed to provide precise aiming even at the longest range and lowest light conditions.

Dead-Hold BDC Reticle

The Crossfire's Dead-Hold BDC aiming reticle is designed to help eliminate guesswork on holdover and windage corrections. This type of reticle is good for hunting or other types of shooting where you’ll be aiming at targets across very long distances. The Dead-Hold reticle can be used effectively with high powered rifles, rimfire rifles, black powder rifles and slug shotguns. The BDC Reticle is constructed in the second focal plane and maximizes long-distance shooting and ranging abilities for your Crossfire II Riflescope. The reticle was marked using MOA based subtension lines as a reference for bullet-drop as well as bullet drift in windy conditions; the ultra-precision laser etching on the glass reticle is kept to the tightest tolerances possible. The BDC reticle has a max windage adjustment level of 50 MOA and a max elevation adjustment level of 50 MOA.

Durable Build

Constructed out of aircraft-grade aluminum, this Vortex Optics Riflescope has a tube size diameter of 1 inch in a single-piece tube designed to maximize alignment for improved accuracy and optical performance. A tough hard-coat anodized exterior combines with exterior coating to help protect your scope protects against bumps, bruises, scratches, oil, and dirt. O-ring seals and Nitrogen gas purging create a waterproof, dustproof, and shockproof body.

Internal Mechanisms

Capped tactical turrets give you extreme control for fast and accurate elevation and wind adjustments thanks in-part to the integrated locking mechanism that prevents accidental adjustments. A fast focus eyepiece brings you quick and easy reticle focusing to lock on to your subject every time. An adjustable objective lens provides easy image focus and parallax removal.

Vortex Crossfire II 4-12x50 AO Riflescope (Dead-Hold BDC MOA Reticle) SKU: CF2-31023

Rated 5 out of 5 by from Great small rifle scope Perfect scope for a .22 rifle. I’ve had this scope for a few years now and I use it for hunting squirrels and target shooting. Enhances your .22 rifle accuracy and makes it a little more fun to shoot. Overall great scope

Rated 5 out of 5 by from Great scope for the price Bought this scope when it went on sale was looking for a 3 to 9 scope and came across this one the glass is super clear for the price and the overall feel of the scope is nice lightweight too would definitely recommend for anyone that is looking for a inexpensive rifle scope to get the job done

Rated 5 out of 5 by from The scope is crystal clear and was a breeze to site in. I was able to put this on my son’s new rifle and he was driving tacks in no time!

Rated 5 out of 5 by from Great product. I have used this out in the field many times, I have this optic on my 6.5 Creedmoor and it works wonders. The glass is clean and clear, hands down the best product. And don't forget about the awesome warranty this company has with all of their optics.

Rated 5 out of 5 by from 10-22 rimfire all day!! Got this scope for several 10-22s after the first I bought to try out. I own 3 10-22s and this is a perfect fit for all of them. Crisp glass and easy to get on target. There are much more expensive options but this glass is perfect for the 10-22!! I shoot my 10-22s 1-3 times a week if not more when the squirrels are out to play!!! Hundreds of acres and tens of thousands of confirmed kills!

Rated 5 out of 5 by from Great scope for the money I have astigmatism and takes a bit to focus on a target. The illuminated recital really helps centering on target. almost looks as if I'm using a red dot. I put this on a Henry Big Boy .357 cal and it works great. It works so well I just bought a second one for another rifle of mine. I would say this scope would suit a beginner up to an expert. I would recommend having it bore sighted initially, to save money by using less rounds to fine tune it in.

Rated 5 out of 5 by from Perfect scope for a 22LR rifle Put this on a Savage 22LR and it was quickly zeroed for 50 yards. Glass is crystal clear and durable. Fell off the bench, landing on the scope, and no damage to be found.

Rated 5 out of 5 by from Great for plinking Mounted this scope on a Ruger 10/22 takedown model. Good glass for the money and was very easy to zero. Very good value for a scope.
