High quality

I bag out every year with my 30-06 and store it, I pull it out and check my zero and it's always dead on. Great scope.

Crossfire II 4-12x40 AO

I was looking for an optic to put on a 17 Mach 2 and this scope for the bill. The adjustable objective is perfectly suited for a rimfire as well as the 4-12 magnification range. So far I have been impressed with the clarity and light gathering of this scope at this price point.

The optic is great for an entry level 4x12. Adjustability is good and glass is clear for the price. Great for rimfire.

Excellent

Liked the first one so well, I purchased another one. Great rimfire scope. Parallax adjustment and fast focus eyepiece really enhances sight picture.

Crossfire ll 4-12x40 ao w/ dead hold BDC

This scope has became my 3-9 replacements as I'm let's say aging and my eyesight is going with it. This little change has really made a considerable difference for me. With Vortex quality across platforms and reticles was really no big deal to start to swap out 3-9's. The dead held BDC Dead hold for me is by far the best reticle choice for me. I have even changed to prism red dots for the same reticle.

Added this glass to a

Added this glass to a tikka 270. Clarity is amazing for the price. Even when at max zoom looks crystal clear. Holds reticle after 200 rounds at the range. Just an amazing product. Not to mention the VIP warrant. That aOne is worth its weight in gold. Excellent choice for beginner to intermediate shooters. Tough and durable for sure

Great for a hunting rifle

Had this on a 22LR for a while and it works great for squirrels since you can adjust the parallax. Liked it so much that I bought another to go on a future 308 deer rifle build.

It's a budget scope

This is the scope for the middle class. It does carry the Vortex warranty. I put it on a Ruger 10/22 to shoot at 25m. The AO is nice, but the scope is big. I wanted the AO and had to take 4-12 magnification. I've set it at 6x and will likely never change it. The turrets are well marked, and easy to adjust. Although a little soft on the clicks and with stacking tolerances, it's really non-linear. I wouldn't put it on anything other than a 22 range rifle

Good scope

Its a good scope. Not the best glass there is but its not bad, for the price it works well. Its a large scope and kind of heavy for the plinking 22 for my boys to learn on. I'd like to have a throw lever for it but other than that its solid mounts. I used different mounts than the ones provided but the ones they provided aren't bad. 4-12X is great and gives some options for my 22 lr Ruger precision rimfire.

Great for the price

This is a great scope for my 10/22. It is obviously not as nice as some of my other more expensive glass, but it has a great reticle, clear glass, and does what it is supposed to. The turret clicks can be tough to feel if you aren't paying close attention. Overall no complaints.

Classic Vortex

Excellent clarity, build quality, and all-around fit & function; quite lighter than expected as well without any compromise on durability. This scope will last a lifetime.

Her First Rifle and Scope

I picked up this new 6.5with the Crossfire on it. It's a good scope. It has the ability to get out to 600 yards. It is a SFP scope for normal <300 yard ranges it is an excellent scope. It served her well in 2021 for her first ever deer hunt.

Decent scope for the money.

Living in the UK and working as a gamekeeper I needed something that I could use with my night vision add on (PARD) on my 243win on a budget. Reading the reviews I was swayed to go for this model. Turrets were my only gripe, Mushy and not easily defined between clicks. Overall performance -7/10

Awesome Performance

I purchased this scope to put on a new springer air rifle. It sat on that rifle for a few weeks and did great. I then sold that air rifle and moved the scope to my new .22 cal PCP air gun. I'm able to make 1st round hits out to 75 yards (max distance at this time) with this combo! I'm working on a drop chart for my air rifle/scope combo for longer distance but at this time I'm zeroed at 25 yards which is my most common shooting distance (back door to bird feeder) for nuisance vermin... It's minute of dime at 25 yds with CPHP 14.3 pellets. This scope is perfect for this! I will be getting more Vortex scopes in the future!

Good, could be better...

Just got this scope put on a 25-06. It seems to hold zero so far and is pretty decent glass at the lower magnifications. The parallax adjustment seems to be off a bit on the lower yardages and the focus doesn't seem to really do much at all. At higher magnifications it gets foggy and makes it difficult to see anything unless you keep your eye in a perfect spot. Overall not a bad scope but wish it was a little better and clearer for longer ranges.

About Vortex Optics CF231019

The Vortex Optics CF231019 Crossfire II 4 - 12 x 40 mm AO Riflescope, Dead-Hold BDC Reticle, MOA is ideal for rim-fire, long range, predator/varmint and target applications. Built to exceed the performance standards of similar riflescopes, the Crossfire is standing by, ready and more than willing to assist you with filling that tag.

With its fully multi-coated optics for optimum light transmission and a fast-focus eyepiece for quick target acquisition, the Crossfire makes quick work of dialing in for the shot that counts. The Crossfire 4 - 12 x 40 mm AO Riflescope has tall capped turrets, which maximize ease of windage and elevation adjustments in the field.

Adjustable Objective (AO) uses an adjustment mechanism on the objective lens to fine-tune focus for the purpose of reducing parallax shooting error. The Dead-Hold BDC reticle helps eliminate guesswork on hold-over and windage corrections. It is good for hunting/shooting at varying ranges where estimating hold-over is a concern.

The solid one-piece aircraft-grade aluminum alloy construction of the Crossfire riflescope is outstanding in strength, rugged and shockproof. Neutral pressure nitrogen purging guarantees waterproofing and fog-proofing that withstands the elements at any elevation.

Vortex Optics CF231019 Features

  • Fully Multi-Coated Lenses: Increase light transmission with multiple anti-reflective coatings on all air-to-glass surfaces

  • Adjustable Objective: Uses an adjustment mechanism on the objective lens to fine-tune focus for the purpose of reducing parallax shooting error
  • Reset Turrets: Allow re-indexing of the turret housing to zero after sighting in the riflescope-generally requires use of a coin or wrench
  • Waterproof: O-ring seals prevent moisture, dust and debris from getting inside the tube for reliable performance in all environments
  • Fogproof: Filled with nitrogen gas to inhibit internal fogging
  • Shockproof: Lenses are locked in place, fore and aft, with machined locking rings to remain in perfect alignment and withstand recoil and impact
  • Hard Anodized Finish: Hard-coat anodization is durable; the low-glare matte helps camouflage the shooter's position
