It's eh

It's a decent optic but the redical is small and the eye box is small. And I find other optics better but I'll put it on a short barrel sooner or later. The glass is great and the quality of the material is nice. Easy to use and it's a nice height to just ok through and don't have to hunker down all the way to the stock. Do recommend for someone looking for something with a little more magnification then a red dot

Perfect for shooting out to 75 yards

Well built, very clear optics, 3x magnification, low weight. Eye relief at 2. 8 inches can be short for some rifles but usually works well for carbine setups.

Eye Relief doesn't work for my eyes

I found target acquisition difficult with this sight on my AR. It could be related to the short relief and my glasses. I also have a Vortex StrikeFire II, and I love it.

Great Value

When you compare this optic to others similar in price, they are much worse quality; and when you compare it to similar quality optics, they are much more expensive. overall, excellent clarity, ready to zero, functional reticle, and the option to mount a red dot on top is awesome. I put mine on a Ruger LC carbine for rabbits and prairie dogs, so far it's only shot paper and steel but it's very easy to hit a 4" steel plate at 100 yards, so I imagine it'll do fine.

Bargain ACOG

I bought my first one used because of the lifetime Vortex warranty. It is a light, handy and compact AR optic with good illuminated ranging reticle. The eye relief could be better but that is my only complaint.

Lens covers

Great magnification, light weight. Serious issue with lens covers constantly getting in the way of target acquisition. Prefer flip covers that don't impede field of view. No aftermarket covers available.

Crisp

The lenses were clear and crisp. Great sight picture for my fun gun. Only complaint is the eye relief is on the poor side. Easy to sight in and reticle is clean.

Perfect

Personally I think this optic is amazing. I was dead set on getting an ACOG with the RMR top mounted. Thats a $2500 optic. After doing some research I decided to mount this on a low height rear extending mount that sits it right over the charging handle. Perfect eye relief. I mounted a defender XL on the vortex 45 degree mount which makes both optics the same height over bore, right in front of the spitfire and this set up is perfect. Durable, high quality optics. The glass is super clear, reticle is great, nothing left to be desired. This set up was a fraction of the cost of the ACOG and it achieves the same capabilities WITH the vortex warranty. Can't be beat.

Excellent Customer Service

Contacted Vortex to replace the mounting screws for my Venom Red Dot mounted atop the Spitfire Gen II. Their customer service is next to none. Phenomenal customer service experience with this company. Also, the optic is great too for a smaller footprint with 5x magnification.

This should be disclosed in the specifications!

I inquired about battery life of this product because it's not in the specifications. This is directly from their customer service (who was very professional, helpful, and replied quickly): "On the lowest setting it is 210 hours, on the medium setting it is 144 hours, and on the brightest setting it is 12 hours." I should add that the two lowest (of 12) settings are night vision compatible. They are too dark for me to see without NV. Considering the battery saver doesn't activate until 14 hours after the last button is pressed, the battery can die on the highest setting before the battery saver activates. When I asked for further confirmation of these numbers I was assured of their accuracy: "Those numbers are directly from our engineers who then forwarded the battery life numbers to us." Which seems odd when other Vortex optics have a 50,000 hour (5.7 YEAR!!) battery life. But it explains why its omitted from the specification sheet. I'm glad I learned this prior to purchasing.

Good optic

I bought this for use on my 12 gauge slug gun. It works great in dense woods. Easy eye relief and target accusition. The BDC reticle is too small to be useful, but since I don't have it on an AR I only look at the main part of the reticle anyhow. Great price for what you get.

First Impressions

Although I've installed the optic, I haven't actually put rounds on paper with it yet. I own several Vortex optics and I've been very impressed with their quality and performance, especially at this price point. I've also taken advantage of their lifetime warranty on one occassion and I assure you it's legitimate. This optic is replacing a Mepro M-21 I'd installed on an IWI Tavor X95. The Mepro has some very cool features, but unfortunately my astigmatism/aging eyes were struggling with the projected reticle. I saw two triangles where everyone else saw one. That's not the case with the SpitFire. The etched reticle is sharp/clear despite my goofy eyes, the glass is clear, and the magnification is perfect for me. Some other reviews criticized the eye relief - yes, it's short, but it only took me a couple of minutes to find the sweet spot and get the crossbolts tightened down. I mounted mine at the extreme rear of the rail which blocks the BUIS. But the beauty of the etched prism optic is that the reticle remains even if the battery craps out. Overall, the optic seems well constructed/rugged and improved over the previous Spitfire models (I have a couple of those too). My first impressions are very, very positive - I'll update once I've put some lead downrange.

Unfortunately, for the cost just get a LPVO. It's Way more efficient. Wished the glass was clearer.

Excellent prism, worst mount base.

It's really excellent lens. Amazing elevation adjustment 200moa ,even could used on crossbow. But the mount base is so bad ,too far away from cheek to use, I shoot my crossbow an hour and I seems like twisted my neck ,Vortex should help me pay the medical bill. Haha. I used another mount , now my neck is better.

Very Poor Design.

Bad design. It's a good telescope, with a problematic design. Placing the lens caps on the battery compartment on the right side can cause pod ejection stops in the weapon. It is forced to turn between the sides of the buttons for controlling the lighting intensity and the battery compartment, in the next generation of the device. Bad design.

Not completely in love

I really liked the prism no star effect for astigmatism reticle. Partially what had me sold. Tho I couldn't find one to pick up and look at. So?. I bit the bullet and bought one and waited. It finally arrived and I get it out and decide to mount it. It has a high and low mount in the box very cool! Had plans on putting on my 45/70 dark as I don't plan on shooting out more than a few hundred yards at most. And found it was not going to work as the eye relief is stupid short!!! Very uncool? like most high power scopes are not needing to be this close. For the moment I decided to build a totally custom mount and mount it. It comes into focus fast and clear. On or off. Is nice and crisp on colors and clarity. Looks like a cross between fallout meets John wick.. weather turned again so haven't had the pleasure of playing any further.

Quality glass and decent eye relief

Shipping was fast and simple, arrived quickly. Optic mounted very easily and included an ar riser as well the bdc holds were accurate so far and illumination works great. I have also forgotten to turn the optic off more than once and the cheap included battery works just fine still (shake awake is awesome).

Extremely good all around optic

I bought this from psa when they were on sale for $200 bucks. I didn't expect much. Now I'm running it on my bcm recce rig with the piggy back venom. All the reviews either complain about eye relief or the mount. All prisms especially this small will have bad eye relief. You need to train so that it doesn't effect you. The mount I immediately replaced with the primary arms one for 50 bucks and it pushed it back and up. Works well when shooting with large goggles or nods. Also someone said to illustrate the whole reticle. Here is why they didn't at night you arnt likely going to need to shoot anything past 200 this rifle has a 50 200 zero so there is no drop until 300 most rifle lights can't even see that fat. All in all great quality option from vortex also the 1 moa adjustment make quick zero and don't cause any problems. This is not a precision optic.

Love Vortex, but this one

Love Vortex, but this one didn't do it for me. The eye relief is way too close and the optic is pretty busy. The mount is nice. I wanted something between a CCO and an ACOG. This does fit that gap... sort of.
