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.

The EBR-556B reticle (Enhanced Battle Reticle) is designed around the 5.56 x 45 cartridge to aid in rapid shooting at both near and far ranges—providing holdover and ranging references from 0-500 yards. Etched directly on the prism to assure consistent point-of-aim at all times with selectable red/green illumination of five intensity levels to match specific conditions.

Rated 3 out of 5 by from good features, poor turrets The scope locks good, and overall the outside is well built. The glass is clear and the reticle and illumination are excellent. Unfortunately the turrets are garbage. They don't track true at all, they move between 0 to 1 moa per click. adjusting it is more of a guessing game then measuring required movement vs moa adjustments. After moving 78 clicks to move 11 inches at 50 yards the scope had also tracked 6 inches left.. you have to bang a few rounds out to "set" your adjustments and figure out if they are going to stay, sometimes they jump a couple moa after an adjustment. This screams "adjustment screws directly on the internal optics tube" that you normally see on $50 chinese optics.

Rated 5 out of 5 by from Perfect for my needs This was the first vortex optic I have purchased. I was torn between it and a traditional scope for my AR. I am very happy that I bought the Spitfire 3x. I had no intention of shooting long distances with this gun, as I plan on using for home defense and maybe a coyote or hog occasionally. It was extremely easy to mount and zero at 100yds, and I've shot it out to 200 with no problem using the hashed reticle. I really liked that the reticle is etched, so that it does not need to be turned on to be able to use it. It's also nice to have the option of using green or red with multiple brightness settings. After shooting with this, and my dad's Aimpoint, I can honestly say that it performs much better than his. I'd definitely recommend buying it!

Rated 5 out of 5 by from Great 3x Optic I bought this optic shortly after it was released in 2015 and it sits on my Daniel Defense 300 Blackout SBR. Clear glass, bright illumination on the reticle, and though the BDC is for 5.56 55gr I use it for my 300 Blackout subs and supers by using Vortex's LRBC to adjust my holdovers. A very good alternative to an ACOG and with the etched reticle you can use with or without illumination. Has a small pic rail on each side but I took those off as they are not needed for me. I messed up and stripped the threads on the screws for the base but Vortex sent me a free replacement. Battery is an easily found battery and optic is just solid.

Rated 5 out of 5 by from Another quality product from Vortex I had originally purchased this sight to put on a shotgun, but after running into a little stag with the mounting I decided to mount it on an AR15. I wanted a sight with high end quality, without the high end price tag and the Vortex spitfire 3X came through with flying colors. I'm a big fan of the EBR (enhanced battle reticle), and the fact the it can be illuminated in green. Also, a big selling point was that the reticle is actually etched on the glass, so if the battery happens to die the firearm will still be useable. The only downfall for me, was that I was not able to mount it on to the cantilever rail system of my shotgun, but has proved to be another great addition to my Vortex collection!

Rated 4 out of 5 by from Awesome I bought one of these a while back in the hopes it would be SIMILAR to the ACOGs I used in the army with out the 1200+ dollar price tag. Honestly it was exactly what I hoped for. it holds zero, turns on every time, it has good eye relief and doesn't add a ton of weight. Here are the cons, It isn't as clear as the ACOG, the reticle is a little small and takes some getting used to. All that being said I have to say if you are looking for a great fixed power optic like an ACOG and don't want to blow 1200 or more then the search is over!!!!!

Rated 4 out of 5 by from 3x spitfire. I've used the 3x spitfire over the last few months practicing for a SDM course. I've had zero issues with it. I've shot 24in steel plates at 500m with 55-75g 5.56 ammo. Mostly Hornady black and frontier with m193 of a lot of brands. It's done everything it was made to do... There's two problems with it imo. There's better options available on the market and the same price or less. The second been the reticle. The cross hairs are thick which makes it harder to get a pin point zero at 100m. The BDC maxes out at 500m while similar offerings go out to 600m. The horizontal marks at 300, 400, 500m work for sizing targets, but other brands have a secondary way to size targets and estimate range. The 3x spitfire doesn't have wind holds. I'd like to see a rethought reticle, or a 4x, 5x spitfire with different reticle.

Rated 5 out of 5 by from Phenomenal Scope I bought this about a year ago for my Ruger SR556 Takedown. I am not shooting at long distances yet but my eyes aren't what they used to be so I wanted something magnified. It was really easy to zero. I love the etched reticle. If the battery fails, it isn't an issue because the reticle is still there. I couldn't ask for better performance. Ryan at customer service is fantastic and patient. He answered all my questions and helped me choose the right optic for my needs. Just ordered another one (SPARC AR) for a 9mm build. You just can't go wrong with Vortex.

Rated 4 out of 5 by from No co-witness This appears to be a quality piece of equipment. It just needs some fine tuning. Glass is clear and I purchased it due largely for the etched crosshairs. It does not come with a Quick detach mount and Vortex does not offer one. You have to go aftermarket and pay $79 to get one. My biggest complaint is the scope sits to high and above co-witness height with the provided shim, and without it the scope sits to low and hits a lowered flip-up sight so you have to move it farther forward. With the short eye relief, the only option is to use the spacer and have it sit high. The wire holding the adjustment caps needs to be relocated to a location where it doesn't interfere with the top light turret. Over all it nice, just needs to have a little redesigning.

Rated 4 out of 5 by from I Want to Like It There are 2 faulty issues with this scope but first what I like. Prism, 3 power, optical adjustment. I have sold both of my ACOGs because if you don't have 20/20 vision you are out of luck. I have 20/30 enough to shoot without corrective glasses etc. so I need my scope to accommodate. I don't think my adjusting the "reticle focus" as it is called would effect the field of view BUT I had to place the scope as far rearward as possible and I still have to push my head forward to get a full field of view. Not good. Secondly the reticle is not trued to the perpendicular, it is slanted to the right. I have a newly patented laser product that proves this so don't just assume some yahoo can't line up a reticle. I don't plan on returning, price is good for what you get.

Rated 4 out of 5 by from Love the concept! I love my Spitfire 3x on my DDM4V7! I love the idea of the etched reticle and choosing between green and red and the intensities of the reticle. The only down side is the poor eye relief it offers. I have to mount it further back on the receiver and shorten the stock up to get a clear field of view. Other than that I really enjoy this optic.

Rated 5 out of 5 by from 300 BLK also Put this on a 300 BLK pistol. Worked the BDC math for my subs and supers. Confirmed with hits at range. Reticle is crisp, works for close or medium distance. Hits on target are stupid easy.

Rated 5 out of 5 by from Amazing Optic I bought this optic a few days ago. The eye relief is great on this optic. I mounted this on my AR-15. I had it zeroed at 100 yards center mass within 5 rounds on a 4in. diameter steel target. No complaints at all. The crosshairs are etched into the optic so if your battery dies no worries you can still have very accurate fire. Amazing Optic.

Rated 5 out of 5 by from Fantastic product I purchased this product around 12 months ago and it has been everything it was advertised. The lenses are crystal clear with great contrast between the red and green site. The adjustable brightness power makes it ideal in variable lighting. It is backed by the best warranty on the market. The spitfire is a top tier optic at an affordable price. I have absolutely recommended vortex optics to friends and colleagues and will continue to buy their products.

Rated 5 out of 5 by from Favorite AR Sight I’ve been using this optic for a year now and I’ve never had a problem with it. It’s accurate, the AR platform doesn’t cause the sight to adjust on it’s own, and I like being able to switch between red, green, and black as the reticle color. It’s easy to adjust the sight and it’s easy to attach my Vortex Venom Red Dot sight to it (canted). Definitely recommend getting it.

Rated 4 out of 5 by from Great scope, badly designed mount Having the mount's bolts protruding from the right (ejection) side was an odd choice. You cannot rotate the mount because of the way the scope attaches. Rather than pay for AMD's branded Spitfire QR mount, I really wish it were an option via Vortex. For now I will be butchering my stock mount in order to have the bolts on the left. Other than that it so far a great option for folks who cannot use a traditional dot and cannot afford an ACOG.

Rated 5 out of 5 by from Accurate scope for S&W AR 15 I took a lot time researching red dots and scopes for my AR because I didn't know what I really wanted in a scope. I know i didn't want a long range scope for a 5.56 but i didn't want 1x either. So I stumbled upon the Spitfire 3x and thought, heck yeah, the best of both worlds, not too far and not too close with tons of options. The first thing I love is that you can go green or red. When you have different lighting situations, sometimes green is easier to see and sometimes red is easier to see, then you have 5 options of bright or dim, that is really awesome. Sighting this in was simple too. Truthfully, from the factory it was perfect, I only had to adjust a few clicks. This thing looks really sick on my rifle. I get a ton of compliments about how fast you can acquire a target and where you can rest your eye compared to the scope. I know i find myself able to acquire targets really quick and field of view is not obstructed either.

Rated 5 out of 5 by from Amazing Clarity Just purchased the Spitfire 3X Prism Scope for my AR and couldn't be happier with the clarity. I own two other Vortex products, Viper PST FFP & the Venom Red Dot. Both are clear and crisp but I was still amazed nonetheless. It's like putting on a pair of reading glasses for the first time. . . I also love having the option of going from red to green illumination and the 3X really helps reaching out (accurately) to 100 yards and beyond. Solid scope at an affordable price and I never have to worry about the longevity of it with the Vortex VIP Warranty.

Rated 5 out of 5 by from Crystal Clear & Crisp Reticle I’ve been using this on my .300 Blackout Pistol for nearly two years. I zeroed the center crosshairs for SuperSonics at 100yds. The bottom subtension hits at 100yds with subs using the same zero. Love that I can switch between supers and subs with same optic and maintain consistent accuracy. This is suppressed and unsuppressed on an 8.5” build.

Rated 5 out of 5 by from Easy adjustments and great glass I bought this scope for my sig rm400. I needed something more then a 1x. Without going to high in magnification. This scope fit the bill without issue. I have found that this scope and 45° offset irons. Is by far the best set up for me. Offering both close and mid to mid long range quick target acquisition. I would buy this scope again if I had the choice. With both vortex VIP Warranty and a name that carries weight. I trust in the fact that a company doesn't become synonymous with quality. Without the work and products to back it up. And the scope stood true to that fact. P.S. I even lost an end cap. Which vortex replaced without question. Within a few days the replacement was in my mail box.

Rated 5 out of 5 by from Incredible scope with an amazing reticle. Mounted this on my AR15 to replace the Spitfire 1x I had on it. I loved the but felt that with my eyes I needed slightly more magnification. I contacted Vortex customer service about a multiplier and they directed me to this gem. I received it and it "looked" cool, I mounted it and it "looked" even better. The real measuring was to be done at the range. It took about 10 round to have it zeroed at 100 yards. Immediately I turned down range to the 200yd target and it was spot on. The EBR-5546B reticle had made taking this weapon out to 300 yards very easy. I have not taken it further but not because of the scope but due not having a range where I can shoot that far. I hope to taking it to a 500yard range soon. Thanks Vortex for a great product and for having world class customer service.

Rated 4 out of 5 by from Amazing Value I bought this scope 7 months ago for my PSA AR-15 I built. And I love it! It looks great, has a very premium quality feel, and is an excellent ACOG alternative. It only took a few shots to zero it in and it has held zero perfectly since despite my moderate abuse. It easily pops targets at 100 yards. The optics are remarkably clear and the reticle is crisp. It is easy to use with both eyes open as well. My only gripes are that the angled rails come loose which is no good but loctite fixes that and that the covers tend to come off a little to easily. I like to sling the rifle over my back when necessary and if I'm moving a lot, the lens covers tend to pop off. It's amazing I haven't lost them yet. In summary: PROS: Looks good Sturdy, quality build Clean optics Sharp reticle Holds zero VIP Warranty CONS: Side rails can come loose with optics on them Lens covers are a little too loose Overall great. Would receommend and buy again.

Rated 5 out of 5 by from Looks great with the H&K MR 556 I really enjoy shooting the H&K with the Spitfire on there. It's crystal clear easy to see the green and red colors. The Spitfire so accurate that sghting in the rifle was so easy and didn't take much adjusting. As mentioned in the review for the crossfire II we have Vortex products on many of our rifles. Thank you for the amazing products and warranty and no hassle free lifetime guarantees. I recommend Vortex to all my shooting and hunting buddies.

Rated 5 out of 5 by from Fantastic scope for the money, on par with Elcan. Used an Elcan 3.4x with the military, but the clarity and reticle on the spitfire blow the elcan out of the water, even though the elcan costs 3x as much. Highly recommended for anyone looking for a robust, fixed magnification, low power optic. Been using it on an AR10 and has held up well after a few days at the range. Only wish is that it came in a .308 reticle. Will be moving this over to a 5.56 Tavor soon, but definitely a keeper.

Rated 5 out of 5 by from Battle ready optic This is one of those must buy optics. No battery no problem. It’s not light, it’s bulky and with the additional 45 degree rails looks like it has its own armor. But it’s crystal clear, handles round after round after round and with the hold overs, coffee cans at any distance are achievable (within reason folks). Pros: everything. Cons: light turret does not find center with markings. Not big, but something.

Rated 5 out of 5 by from PERFECT! I did a lot of due diligence on AR optics before choosing the Spitfire. Couldn't find a negative review anywhere! Main concern was vision issues at age 60. My last optic was an Eotech. Fired one of these bad boys up at my dealer and was sold on it immediately! Absolutely amazed at brightnss and clarity of reticle. Lifetime warranty a big plus also. When I build my AR-10, it will sport a Vortex scope as well!

Rated 5 out of 5 by from Perfect scope for almost anything. I bought this for my 1st ever AR. I wanted something that I could use at both under 50yds and still have some magnification to stretch out at 150yards and boy did this deliver. I can see the target at 25 yards clear as day and then when I want to challenge myself I can hit a target at 150 and have even reached out to 300yards on a good day to constantly hit a 8in steel target. I would recommend this to anyone who wants a little bit of everything. The scope looks and handles nice. I've had it for more than a year now and it holds zero perfect.

Rated 4 out of 5 by from good product I mounted the Spitfire 3x Prisim Scope on my new AR, I haven't had the opportunity to take it or the AR to the rage yet. However looking through the scope I like the way it is setup. The optics are very clear and the EBR is clear when you view it in the scope. I have other Vortex products that are great and that is why I purchased this product after looking a many other scopes. You cant beat the warranty and the no questions asked return policy. Haven't shot the scope so can't really rate the accuracy or performance of it that's why the 4*.

Rated 5 out of 5 by from Great opticals for a great deer hunting gun I mounted a spitfire 3x on a Windham Weaponary SRC .308 for deer hunting in Minnesota. I hunt the big woods where a long shot is 125 yards, but more often around 50 yards or so. What I liked most of the scope is how easily it picked up my target (in this case a deer) in the woods. The lighted retical helped tremendously with identifying the vitals for a quick and accurate shot.

Rated 5 out of 5 by from Excellent optic for the money!! I purchased this as an economical alternative to an ACOG (TA31RCO), and I have to say I'm loving this optic. Having used an ACOG many times before, the Spitfire is very comparable as far as features, reliability, and durability. I've beat the H**L outta this thing, and it's maintained zero through it all. The reticle is super easy to use, and again is very comparable to the ACOG as far as utility. While the ACOG does have the fiber optic illumination option, which is nice, it really is more of a gimmick in most field applications.

Rated 5 out of 5 by from Top Notch I bought the Spitfire 3x for my AR after reading 50+ reviews. I couldn't find 1 single review that had anything negative to say about this optic. Everyone knows Vortex, everyone knows their warranty policy, customer service and quality is the best in the industry. When I received the optic, I was shocked at how solid this thing was. It's an absolute beast. The clearest glass I've ever owned, by a long shot. It's an absolutely beautiful piece and I would have paid twice what I did. I'm a Vortex lifer and proud of it!
