Rated 5 out of 5 by from Fantastic Scope This was my first Vortex scope and mounted it on an 18" 5.56 build with 1" Vortex high rings. Mounted very easily and zeroed even easier. This scope is crystal clear and is well built. Bought this for the price and unmatched VIP warranty. Four months after original zeroing it is still dead on. My son came home from NYC for a visit and we went to the range. He took the first shots.....3" AR500 knock-down targets at 200 yards.....5 shots and 5 direct hits. This is a great scope. Vortex has a new life-long customer. My next Vortex is going to be the Sparc ll for my new 10.5" 300 Blackout build. Great scope, great company, great warranty.

Rated 5 out of 5 by from Awesome optic, especially considering the price! I bought an .17HMR last year and it came with a cheapy 3-9x40 scope. Well, I fell in love with shooting that little rimfire and felt I could shoot sub-MOA with a better scope. I'm so impressed with this Crossfire II that I'm looking at getting another for my .30-06! It's bright and clear, and everything is crisp well past 200 yds. The eye relief is great even cranked up to 12x, and the sight stays sharp, I can see the holes in the paper at 100 yds. Like I said, I'm looking at buying another for my hunting rifle, it seems durable enough to go through the elements with me during fall hunting.

Rated 4 out of 5 by from Good value in a value priced scope Bought a Crossfire II 4-12x40AO scope for a 7mm-08. (Aging eyes need a little more zoom). Clarity is great even at the glass edges. The MOA adjustments surprised me as they were spot on when an adjustment was needed during sight in. Ten clicks moved the POI 2.5" @ 100 yds, really good for a lower end priced scope. My only complaint is the sight picture gets a little smaller at the higher zoom levels. At 11-12 power you need to get your eye in just the right place to see a full view through the scope. Overall the scope works fine for me and I would recommend this scope to anyone who doesn't want to spend a lot on a good accurate, clear riflescope.

Rated 5 out of 5 by from Awesome quality and support makes Vortex my "Go To" optic. I bought this scope for my AR-15 build. I had it zeroed at 50 yards in 3 rounds. The optics are very clear and bright and for the money I believe it's an excellent scope. I can't wait to get it out to the 300 yard range. It comes with a 4 inch long sun shade that works well. I liked it so much I bought one for my wife's AR I built. She loves the scope too, though I think she would prefer the less busy V-Plex reticle. I alos have one on my CZ452 American.The no questions asked Vortex life time warranty makes this an excellent scope for those wanting to shoot longer distances.

Rated 5 out of 5 by from So real to life...It is This is my first Vortex product and might I say not soon to be the last. I was urged by my brother and cousin who are both firm believers in the Vortex line to give it a try. My first impression was how unbelievably strong the shell itself was. Then at first glance through the optics I was sold, it was like looking at everything that was once out of reach, fuzzy, and not quite right in crystal clear view. It was if I could reach right out and touch it. Never again will I waste my time or money on lesser quality optics, and with the Vortex warranty how could you go wrong?

Rated 5 out of 5 by from Crossfire II 4-12x40 I've come to love my vortex products, unbeatable warranty and great glass. I've had this scope for 3 seasons. It holds up to the beating it gets in the gun scabborn mounted on the trusty horse. This scope is a great buy for someone that doesn't have the funds for the higher ends models, which are priced very fairly, for what you get. When I get another barrel for my Thompson Center I most definitely will be mounting it with another vortex scope. I had an older Leopold scope on another rifle of mine, for half the price this scope definitely beats it.

Rated 4 out of 5 by from Pleasantly surprised! The scope has a slightly larger objective lens than I realized - my fault, for basing it off the similar one in the case, instead of checking listed measurements. So my rings and mounts didn't work for this scope and my rifle, and I had to buy new mounts. But once mounted, this thing sits my AR like it was born there. I would happily mount this scope on any of my other rifles. It sights nicely, once all is adjusted and zeroed properly, and it holds zero through about 75 rounds so far. As stated, the scope is a bit bulkier than imagined and, though it was my fault for not being prepared for it, I'm still not particular fond of the bulk. This is my only reason for giving the review a 4 out of 5. Overall - yes, i'd buy this scope again.

Rated 5 out of 5 by from Best scope at this price point I put together a Kidd 10/22 recently and decided this would make for a nice optic for 25 yard bullseye matches. So far, my absolute worst group (using blazer) has been 0.8 MOA. Clarity and light transmission down in the fairly dark range are excellent. Focus is spot on, although, I prefer a side parallax, having AO on a scope in this price point is phenomenal. I have been considering moving this to my 308 to replace my PA scope, but I'll probably look at buying something like a diamondback or a PST for that.

For a Remington 700 ADL Short Action {308) would i need a 20moa or a 0 MOA rail with the medium rings? i don't plan on shooting >500yards. I'm thinking of going with the 0MOA, but i would like to be sure. 

Asked by: sambo1984
If you are planning on shooting less than 500 yards, the 0 MOA rail would work great.

I'm looking at the Crossfire II in 4-12. Plan on Deer hunting with my max shot range of 500yds. At 100- 500 yard shots should I get the 4-12 AO or not ?

Asked by: bdog2003
The AO would not be necessary, but it does help tune out parallax. The downside is that if you need to adjust it, that will slow you down. Give us a call at 800-426-0048 ext 5 if you would like to discuss further.
