Vortex Red Dot Reviews

1. Crossfire Review

Vortex Optics Crossfire Red Dot Sight Gen I - 2 MOA Dot (CF-RD1),black
  • The super-light, ultra compact, insanely-fast-on-target Crossfire Red Dot was designed for close-range and general shooting.

Looking for the most affordable Vortex red dot sight?  This is it, the Crossfire.  Its simple, easy, and no-frills design makes it one of the most sought-after red dots in the market.  The low price is just the cherry on top.


  • Price
  • 2 MOA dot
  • Super-light
  • Ultra compact
  • Waterproof


  • Power/battery contact issues

The Crossfire is an optic that's self explanatory - it's that simple.  We could end the review right here, but we'll talk it up for a minute.

A 2 MOA dot gets you on target within micro seconds with its 11 daylight bright intensity settings.  It's ultra compact at only at 2.5" and super lightweight at 5.2 oz.  It's waterproof, has FMC optics, and it comes with an included and widely available CR2032 battery that's supposed to last 7000 hours at brightness setting 5.

But, there has been complaints about the dot flickering on and off during recoil.  This is either due to  poor battery contact with the power knob or battery compartment/fitment.  For those who had this issue, a new battery cap or replacement was sent to the buyer - thank you VIP warranty!

Oh, we should mention the skeletonized mount is a hit.  It keeps things looking streamlined, sheds weight, and it provides two mounting positions: low and lower 1/3 co-witness.  Mount it with the included T-10 Torx wrench, pop off the included lens covers, and point and shoot.

2. Venom 3 MOA Review

Vortex Optics Venom Red Dot Sight - 3 MOA Dot Hat
  • The Venom Red Dot Sight-3 MOA promotes rapid target acquistion while providing a precise point of aim; getting shots down range and on target fast. The Venom's aluminum...

Red dots don't get smaller than this, come on, it's barely 2" tall and it weighs next to nothing, 1.1 oz.  While the Venom with the 3 MOA dot tops the charts as an insanely, highly-ranked paintball red dot sight, it's good enough for nearly any application you need when speed is the aim of the game.


  • Price
  • 3 MOA dot
  • Compact
  • ArmorTek
  • Waterproof


  • Battery compartment/fitting issues

This Venom sight has the daylight bright 3 MOA dot that can be set at 10 different brightness settings or auto mode to suit your eye comfort and lighting conditions.  A CR1632 battery is included in the purchase, and it's what will power your red dot for anywhere in between 150 to 30,000 hours depending on usage.

But, there's a trick to getting the battery screwed in with the perfect fit.  Other buyers say you need to remove the black gasket that's attached to the underside of the battery cap.  By removing it, the cap will "catch" onto the threads to be properly screwed into place.  Problem solved - if you had any in the first place.

Optics are fully multi-coated (FMC), and it even has Vortex's exterior ArmorTek coating to protect against debris, scratches, and all the like.  Don't forget, it's water and shockproof - so it's durable and ready for use for your next shootout - even if it is paintball style.

3. SPARC II Review

Vortex Optics Sparc II Red Dot Sight - 2 MOA Dot
  • The highly compact, daylight bright Sparc II is packed with performance features and lends itself to a variety of platforms.

The SPARC II is one of Vortex's highest-selling red dots to date.  Wondering what SPARC stands for?  Wonder no more - Speed Point Aiming for Rapid Combat.


  • Price
  • Compact
  • Lightweight
  • 300-6000 hours
  • Multi-height mount system


  • Coarse brightness settings

The 2 MOA dot is designed to get you rapidly on target for close quarter shooting when you need immediate target acquisition.

Although there are 10 brightness levels, it's been mentioned more than a few times they're a little coarse - they can go from being too dim to too bright with one rotation.  Overall build quality has also been mentioned as a disadvantage, but for the price and needs of non-professionals, it's worth dealing with or sending it in for VIP warranty coverage.

Control buttons are on the left and face the user.  This is a feature that's not often recognized as an advantage, but when you can use your left hand to make adjustments without moving your trigger finger, you'll learn to appreciate it.

What about mounting?  The SPARC II comes with a spacer, high mount, and low mount for use with Picatinny or Weaver rails.

So far, it's speedy to mount, see, and aim with.  Does it live up to its name as one of the best red dot sights?  We'd say it does.

4. Spitfire 3X Prism Scope Review

Vortex Optics Spitfire 3X Prism Scope - EBR-556B Reticle (MOA) with Vortex...
  • The Spitfire 3x Prism Scope excels in close to medium range shooting applications where fast target acquisition and speed is of the essence. The prism based design allows...

If there's a scope that proves people will spend more to get an upgrade in quality, it's the Spitfire 3x prism scope.  We've bent the rules as it's not a red dot.  But, being lumped in the same category by Vortex, we're reviewing it as it's still one of the most popular optics you can mount to your AR-15.


  • 3x magnification
  • Glass-etched reticle
  • Red/green illumination
  • EBR-556B reticle
  • Accessories included


  • Short eye relief

As a prism scope, it has a glass-etched reticle that many shooters recognize as a high-end feature.  With it, your reticle is always highly visible with or without the red or green illumination.  This EBR-556B reticle is designed for use with 5.56 x 45 cartridges.  It's a BDC style reticle that drops down for holdovers out to 500 yards, however, it's been said to be smaller than expected and may take some getting used to.

With short eye relief of 2.8", its mounting position requires quite the adjustment for its users but has still said to be usable without safety issues.  With 3x magnification, it offers more power than the 1x of red dot scopes.

We're seeing a trending pattern of customer satisfaction, and the Spitfire 3x is consistently compared with 4x32 ACOG scopes but without the hefty price tag.  The masses have spoken - it's a winner in its field.

5. Razor 3 MOA Review

Vortex Optics Razor Red Dot Sight - 3 MOA Dot
  • The Razor Red Dot Sight-3 MOA is designed to be mounted to a wide variety of firearms and used in various shooting applications. The Razor was designed so shooters have...

Top-tier performance and build quality is what you expect from the high-end Razor series, and fortunately, it's what you get.  With a 3 MOA dot, you can achieve higher precision for everything from competition shooting to close quarter tactical use when on duty.


  • Daylight bright red dot
  • XR FMC coatings
  • ArmorTek
  • Side battery compartment
  • Waterproof


  • Awkward power controls

The Razor red dot is easy to get, mount, and use.  It comes with a 3 MOA dot that's excellent for close quarter shooting to some extended shots out past 150 yards.  The dot is daylight bright and there are 9 brightness levels to help match its intensity for the time of day you're out and about.

However, adjusting the brightness levels or even just powering it on has said to be a little awkward or difficult to operate because of its location.  It's not a deal-breaker feature, just something that may take some getting used to.

With XR FMC (Fully Multi-Coated) coatings on a premium wide field lens, Vortex guarantees crisp, edge-to-edge sharpness and resolution.  The exterior ArmorTek coating will protect your image quality in the worst weather while build integrity is supported by O-ring seals for waterproof protection.

At home on rifles and shotguns, it comes with a Picatinny mount for your convenience and the needed tools to sight-in.  As a side note, if you plan on mounting to a Glock, you'll need to look into compatible mounts before purchasing the Razor.
