Fixed-power prism scopes have been topping ARs for decades thanks to their simple, compact and reliable design, but few have come close to the combination of value and performance of the Spitfire 3x. A custom BDC reticle, designed to subtend with most popular 5.56 cartridges, takes all the guesswork out of the equation on shots from 0-500 yards. Meanwhile, the glass-etched reticle can be used with either the red or green illumination, or without any power at all like a traditional riflescope, making for an inherently reliable, “Always ready” platform.

Battery Life: Up to 250 hours on highest setting. Up to 3,000 hours on lowest setting.

Prism Scopes are not compatible with the VMX-3T Magnifier.

Rated 5 out of 5 by from Special forces love it This scope even impressed my buddy who is a former army special forces. The prism is bright, the construction is tough AND the customer service is unheard of. When I called to replace the mounting screws I lost they sent me new ones, FREE without verification that I actually owned one of thier scopes. Vortex all the way!

Rated 5 out of 5 by from Great options for an ar Had this about 6 months. I like the red or green option, I also like that the reticle is etched on the glass so the illumination isn't needed to use the sight. The adjustment caps remain attached to the sight to prevent loss. Overall the quality and milling is superior. Vortex will be the only sights I use

Rated 5 out of 5 by from Amazing Optic I’ve been using my Spitfire 3x Prism Scope with the viper red dot mounted on it and it’s been an unstoppable pair. Target acquisition is fast and easy with the Spitfire zero’d at 100m and the Viper zero’d at 25m. Thanks for an amazing product, super reliable and I have had no issues with either sight!

Rated 5 out of 5 by from The crown jewl of my AR This scope has been reliable and accurate since the moment I bought it! Being able to easily zero and choose my preference on recticle illumination has been great!!! It gets 5 stars in my book and I am a tough judge! If you want reliabilty by a name you can trust go with VORTEX!!!!!!

Rated 5 out of 5 by from Excellent Optic! I have this site on my AR-15 300 Blackout. It has been one of the best optics I have used. Holds zero, laser etched reticle, low battery consumption, and very easy to use! I constantly promote this product to everyone I speak with about firearms and tactical training and range practice.

Rated 5 out of 5 by from so clean, so clear I purchased this optic a few days ago and its performed better than expected. Took only about 20 rounds to get a zero and now hitting 12in steel gong from 275yds. Great scope for the money. My younger brother has the 1x magnified spitfire and it works flawlessly as well. Great products.

Rated 5 out of 5 by from Great AR optic I’ve had the spitfire mounted on my .300 AAC build for a little over a year now and have not had one single issue. Very clear sight picture. Easy to get on target. Very accurate. The red/green option really helps in different lighting when out in the woods. Great product.

Rated 4 out of 5 by from Love my Spitfire All the best features of an ACOG, at a fraction of the price, while still maintaining outstanding quality. A touch on the heavy side for an optic this size, but it keeps it's zero well, is rugged and durable, and the adjustable zoom is perfect.

Rated 4 out of 5 by from Solid optic I've had the spitfir 3x for 3 years now, and I have been very impressed with it. The glass is clear and the reticle stands out. The large field of view allows you to spot your hits pretty easily and using the cross marks allows you to judge distance pretty quickly once you figure out how to use them. My only complaint is the eye relief is much shorter than that of the scopes I'm used to so that took some getting used to. Overall however, this is a solid optic and I am very pleased with it.

Rated 5 out of 5 by from Spitfire on a crossbow For those who don't know this, but a Spitfire 3 sits nicely on top of a crossbow. The glass is fantastic and let's plenty of light in for those precious first or last full minutes. 6 different lighted reticle settings in red or green. On my my crossbow the crosshair is set at 30 yds and the bottom dash is dead on at 40yds. Reticle is etched in the glass so it can't get bumped off of zero. The base tightens down super tight. Trust me, it stays dead on. Great set up for that serious hunter!

Rated 5 out of 5 by from Great scope Got this scope for a new AR I bought. This was my first Vortex product. I have used many different optics and scopes during 24 years of military and LE work and this product is comparable or superior to optics that cost 2-3 as much. This optic is user friendly and has good ergonomicsa d is well built. Zeroing was quick and easy. I really like the reticle. The upper half circle portion makes close range engagements quick and intuitive. Scope was very accurate out to 300m (that’s was the limit to distance I had available). The view is crisp and clear. The reticle itself is sharp and well defined. The ability to illuminate the reticle is nice for low light shooting. Battery life is great. I accidentally left it on for about 24 hours and it was still super bright. This optic can be used with both eyes open, which has so many advantages. You can’t beat this optic. It works great and the price is very reasonable and the VIP warranty is amazing, no other company I know of has a warranty like this. I will be purchasing more Vortex products in the future. This is an excellent optic for

Rated 5 out of 5 by from I Want Another One Just Like It After much thought and reading, I decided on this model Vortex. After mounting it and looking through it at home, I wondered if I'd made the right decision. A friend and I went to the range, as we both had new scopes to zero. The first thing I noticed was how easy it was to stay steady on the target. Couldn't explain it, still can't, but it was easier to hold on target. At 100yd it was just as steady. I didn't mention it to my friend and he wanted to shoot my new rifle, but he said the same thing. He ordered one the next day. Everything is solid and has a good quality feel to it. The adjustments for the lighted reticle is perfect. The green seems easier to see in dayligjt, however all my shooting was done without the reticle being lit. I can't wait to shoot again. They have it together on this one.

Rated 5 out of 5 by from Perfect match for my AR5.7 I bought this red dot from a recommendations from Vortex guru Ken. I couldn't be happier with this choice. Whether I am shooting at 50, 100, or 200 yards, I am shooting 1" groups. The 3x is just enough magnification to see a the target at 200 yards. Also, I can't forget about the illumination. Being able to choose between green and red is great, also being able to choose the brightness. Since purchasing this Ken has directed me on 2 more vortex optic purchases that I am very happy with.

Rated 5 out of 5 by from Outstanding quality for the price! I can't say enough about how awesome the Spitfire 3x Prism scope is. I've currently got it mounted currently on my AR and must admit this sight is extremely accurate to 200yards. I haven't been able to test it beyond that but for what I use my AR for I don't really need to. I'm using it for predictor control on our hunting land. The Spitfire optic is crystal clear and on par with the Leapold rifle scopes that I've purchases in the past for my hunting rifles. The red/green settings are bright and are easily seen on the brightest of days against just about any backdrop. The sights build quality is stellar too. All in all I would definitely recommend this optic to anyone who needs one. I've been nothing but impressed and will definitely consider Vortex optics again when I need to purchase any other optics.

Rated 5 out of 5 by from Easy to use! I run this optic on my suppressed 300blk and LOVE it! Have it dialed in at 50yrds and have even reached out to 200yds with it! Couldnt be any happier with this product!

Rated 5 out of 5 by from Just what I needed! Was looking into different sights/ scopes for my first build and didn't think there was an option that was "small" (not a full rifle style scope) that had fixed zoom. Then I stumbled on this and fell in love with it right away. Watched torture test on YouTube and Vortex warrentee/ customer service is known to be the best... Bottom line this is perfect for my build, just enough zoom to be accurate when needed but not to much where you can't get on target and quick shoot

Rated 5 out of 5 by from Excellent optic for the price! I bought this optic for a recent AR build that I put together, I was looking for a magnified optic for some longer range applications, but that would still perform at short distances (I didn't want a 1-4,6,8x scope). I zeroed the optic at 100 yards with 55gr 5.56x45, the process was no more difficult than any other scope, then I immediately took it out too 500 yards to test the accuracy of the EBR-556B reticle...and it was spot on! Using the 500 mark on the reticle I held slightly high (I was around 525 yards not a true 500) and sent 3 rounds down range, putting all 3 in group that would fit well inside a torso sized target just slightly left due to a small amount of crosswind. I then went back to close range shooting at multiple targets from 10-50 yards, Using a trick by closing the front scope cap, turning on the illumination, and with both eyes open super-imposing the reticle for the super close targets, which worked extremely well. Overall I really enjoy this optic and I think it serves it purpose very well, if I had to pick out a downside it would be the eye relief...but I was already aware of it before purchasing the optic, and the poor eye relief is to be expected anyways with prism scopes.

Rated 5 out of 5 by from Just buy it I have one of these attached to my CX4 and I couldn't be happier. It's small, it's sharp, it's bright, and although the eye relief isn't great (the biggest shortcoming of prism scopes) I had no trouble modding my integrated rear iron to accommodate it. I've learned to like the reticle too, and the build quality is rock solid. Even the caps are good quality. I will say, the one reviewer who mentioned that the turret clicks aren't consistent was right, but mine does stay put after I set it, it's just a little fiddly to tweak it to zero. It actually held zero mostly even after removing and reattaching to the gun, to my surprise, and after poking at it with a handful of test rounds I'm back to ringing the 200yd gong and wishing I had a 250 or 300 to try for. If you want a compact scope for a carbine, get this and don't look back.

Rated 5 out of 5 by from Much better than any red dot/magnifier combo! I owned this optic a few years ago and wish I had never sold it! This reticle on this scope is amazing! The eye relief is perfect for an AR. Great for those with an astigmatism that want to shoot an illuminated optic. When I had it, this optic was used on an AR-10 for hunting and plinking. I carried it through the woods many times, dropped it, bounced it off trees, and it did not lose zero one time. Wanting a low power magnified optic? Get this one!

Rated 5 out of 5 by from No stress. I bought to put on a newly built AR that I had not shot yet. I was expecting to spend some time getting it sighted in due to the fact the rifle and the scope was both new to me. I thew it on and 9 rounds later I was zeroed and good to go, it was by far one of the easiest I've zeroed on. On top of that all 3 of my son's ages ranging from 4 to 8 shot with it and was for the most part on paper, so definitely not a difficult optic to use.

Rated 1 out of 5 by from Not worth it. I love everything about the scope but the eye relief is so short you have to basically place your eye on the rear of the optic. I love Vortex but not this product.

Rated 5 out of 5 by from Fabulous Optic I purchased this scope to replace my Strikefire II red dot, due to astigmatism. Mounting took about 10 min. and around 15 min for sighting in. Since I only had a 25 yd. range to work with, I used an Arma Dynamics target to achieve a 100 yd. sight in. The glass is clear and the reticle is sharp. After sighting for 100 yards, I used the 400 yd. crosshair to shoot this target at 25 yards. I highly recommend this sight!

Rated 5 out of 5 by from Excellen for my requirements. I have one of the 3X on my SBR for use here on my Ranch. I am in and out of the Kubota all day. It has been bumped around, dropped a few times and continues to hold zero. I enjoy not having to turn on the reticle for fast shots on predators but can if needed. it ranges out to the limit of my rifle (400 plus yards) exactly as it claims. Built another upper and used this same piece on it. Keep making excellent products.

Rated 5 out of 5 by from What a great optic After buying a different brand of red dot that I spent hours trying to sight in to no avail I purchased this spitfire 3 what a difference easy to sight in holds true I wouldn't hesitate to buy another one when I get another rifle this is my third vortex product and vortex is the only brand of optic I will purchase between the ease of use the warranty and the quality there's no reason to look at other brands

Rated 5 out of 5 by from What else could you ask for? I am a property manager in SC and my AR stays in the truck with me all day. I have to have a sturdy, reliable, and fast acting optic to deal with my everyday use. This thing is perfect! Just enough magnification for long shots, but still gives you quick sight acquisition. Love the etched reticle, I can get on target without having to turn a knob or hit a button, but when controlling the hog population at night I can turn on the red reticle and it stands out clean and clear in my green surefire game spotter's light. The glass is extremely clear and gathers plenty of light for those late afternoon shots. I can't say enough about this optic, it's like it was made for me. I own a couple other Vortex optics (and will own more) but this is by far my favorite. I've used all kinds of optics, from Swarovski, Zeiss, and Trijicon all the way down to Tasco, and in my opinion, you just can't beat a Vortex.

Rated 5 out of 5 by from Serious bang for the buck! I love the features of this scoop. I love the fact that it has a variable color and brightness for but also features a engraved radical in case of dot failure. Being a Veteran and now Law Enforcement having a backup system in the field is very important. "1 Is none and 2 is 1!" All this and at a price "real working" people can afford with the best warrant in the business! Thank you Vortex!

Rated 4 out of 5 by from Better than I expected. I got a spitfire to put on one of my rifles while I saved for a more expensive optic. I was surprised b the quality of the glass and eyereleif the reticle is simple and BDC was on, I also like the dual colors of the reticle so I can change i biased on the environment. I use another fixed power Optic on my duty carbine and the Spitfire has better glass and seems to be nearly as durable.

Rated 5 out of 5 by from What A Great Optic!! This is an AMAZING product! I bought it with the intention of using it as a close to medium range optic and it fills that role perfectly. I love the etched reticle, giving me peace of mind that if anything happens to the battery or electrical circuit, I will still be able to use the optic instead of resort to my BUIS. I am even able to use this site with both eyes open (Bindon aiming concept) though it does take a bit of getting used to as the optic is running at 3X magnification. The only drawback to this optic is that it doesn't allow you to co-witness your BUIS. However, as I mentioned earlier, this is not an immediate problem as the reticle is etched into the glass. If you prefer to have the ability to co-witness your BUIS I recommend going with the 1X Spitfire or a Strikefire. Overall, I definitely recommend this optic to anyone looking for something sturdy and reliable to drop onto their AR build.
