There may be many variables with most scopes and red dots but with the Vortex Razor HD 1-6×24 rifle scope, things like durability, stagnant zero, and quality display are made constant. Vortex sets the benchmark for a widely accepted gun scope both in the 3-gun and other tactical communities. To be fair as a shooter that has had a taste of what quality is, the first thing you want to clarify about a new scope product is how much forgiveness it gives your eye. With this being one of the most impressive features of the Vortex Razor HD 1-6×24 rifle scope, you probably have not handled any other optic that cares for the positioning of your eye behind the lens and the placement of your head.


With this scope, you could shoot in impossible positions in 3-gun matches just because your eye has received forgiveness. This feature is combined with a reticle Illumination that shines bright, even in the daylight. Brightness settings for this scope would seamlessly go all the way up to eleven, giving you a large room space to make adjustments to how you would want your scope’s reticle lit. At the highest setting, you’ll be thankful to get a bright display and at the lowest setting, night and daytime shooting are still feasible. The Vortex Razor HD 1-6×24 rifle scope is small in size and is powered by a standard CR2032 coin-style battery that stays in the brightness adjustment turret.


Essentially, the Razor HD Gen II series have stellar glass quality which makes it a selling point. Your magnification may reach its limit but this optic is literally independent of the scope’s magnification and will still make spotting targets as far as 1000 yards look like slicing hot butter. Many times, what a shooter needs is a good optical resolution that beats any magnification which is what you get with the Vortex Razor HD 1-6×24 rifle scope.

Next up we have an optic that is designed with a housing shape that takes all the blows and ultimately yields good productivity. For a 3-gun, you need a reticle dot that is visible enough for fast shooting in quick close-quarter engagement and at the same time, small enough to enable you to make distant shooting. This is what a 3.25 MOA can do. The brightness level of the Trijicon RMR Type 2 could go up to 8 with two suitable for night vision and one for ultra-bright daylight shooting. As its name RMR (Ruggedized Miniaturized Reflex) implies, this optic is able to withstand some degree of brutal treatment basically because of its military-grade aluminum alloy housing that gives it a strong shelter to absorb recoil.


This optic is powered by a single CR2032 lithium battery that can take it for 4 years without having to change the battery. Unlimited eye relief is yours for the taking with this optic. A relief that makes it easy for you to aim at your target from varying distance or angle and preferably with both eyes open. This feature makes it more suitable for shooters with cross-eye dominance. Similar to the Vortex Razor HD rifle scope, you can also lock out the settings of this optic but this time you deploy push-button assistance. The clarity of the glass is brilliant, multi-coated to absorb light and protect your eyes from glare. Take reflex shooting into 3-gun shooting with the Trijicon RMR Type 2 sight and be sure to kill the competition with pinpoint accuracy.

3-gun is all about reliability. You won’t get anywhere near accomplishment if your optic cannot stand to deliver strands of shooting performances that are not commonplace. 3-gun shooting may not sound like a battlefield scenario but this optic imports the experience you get in a war zone to your domestic shooting. This model gives you an enhanced visual in your target for quick acquisition with a runtime of 30,000 hours. Without turning off the Aimpoint PRO, it can serve all of your shooting purposes for 3 years. That’s huge! Talk about strength, you won’t find many other products standing close to the Aimpoint PRO.


Forged and hammered out of anodized aluminum with black-matte finishing, this optic will proudly survive tough treatment. You can submerge it underwater up to 150ft deep or keep under temperature ranging from -49°F to 160°F, it still comes out strong and fine. Many scopes and red dot sights prove their durability by being able to withstand shock and heavy rounds of magnum but this optic takes a lead in the race of durability with its bombproof body. I know you don’t expect an explosion in a safe 3-gun shooting but just so you are guaranteed a lifetime of use, manufacturers have put in extra effort to ensure that your optic stays protected, even from bomb explosions.


Glass clarity as we discussed earlier in this review, is the foremost quality a shooter will look out for before checking other added features. Once glass quality is low, the optic is rendered less useful. The glass quality of the Aimpoint PRO is truly on point, with 10 brightness settings; levels 1 to 4 are night-vision compatible while levels 5 to 10 are suitable for daylight shooting. Just as you would expect from a lasting product, the eye box is forgiving and parallax free. You don’t need to look further for an optic that will fit on your gun, promising to see you through seasons of shooting.

Somehow, somewhere in your shooting adventure, you would have heard the name Bushnell. A company that produces binoculars, red dots, and spotting scopes with an extended product line of the AR Optics. 3-gun shooting is a good test of your competence with different types of guns and with the right scope, there is no limitation to how precise you can shoot.

  • Dimensions:
    16 x 6 x 4 Inches
  • Weight:
    19.2 Oz

The Trijicon AccuPoint 1-6×24 rifle scope is a versatile optic that can serve different types of shooting with varying skill and style. This scope is one that can be relied upon on any of the 3-gun competition menus. Offering one of the best tactical scope available in the market, Trijicon has made this optic attract a decent opinion on being one of the best shooting aids for the 3-gun. With a multi-coated, appealing lens that gathers more light for a bright display, your experience is about to take a new turn. Different from other scopes and red dots that we’ve reviewed so far, the Trijicon AccuPoint 1-6×24 rifle scope does not depend on battery power for Illumination. It is built with a fiber optic that adjusts the brightness of the scope automatically once the external light supply begins to reduce.


The Trijicon AccuPoint 1-6×24 rifle scope has a sturdy housing that is constructed from aircraft-grade aluminum. A very good choice to make when going for a scope that will stand any weather condition, and will not wear or tear as a result of frequent use like most less durable scopes. Take it from Trijicon, this optic is not susceptible to rust, scratches, or corrosion. If you want to go hard on your gun, let this scope help you with that. Shooting with one eye is quite common and acceptable amongst shooters but with this optic, you can accurately aim with both eyes open. Since the goal of 3-gun shooting is to hit a target precisely, a second focal plane optic will add to your advantage as the dot remains unaffected with a change in magnification.


  • Deploys the use of a tritium lamp for illumination (not needing batteries)

  • Has resettable adjustment turret

  • Waterproof


  • Reticles are limited in use

  • Maximum magnification (6x) is quite on the low when compared to other models

  • Dimensions:
    3.25 x 14.5 x 3 Inches
  • Weight:
    0.9 Pounds

We are a few steps from the bottom of our review ladder and we have next to the Weaver Tactical 1-5×24 scope. If you are shooting an AR carbine, then set some money aside to purchase this scope. The reticle on this scope is designed by Weaver and is called Close-Intermediate Range Tactical (CIRT). The illumination knob gives you room to light it red or green and is dependent on which way you make the turning of the knob. The entire reticle of this scope is illuminated to suit low-light shooting, although the illumination at 1x is not bright at daytime due to its first focal plane design.


This scope is powered by a CR2032 battery with one extra, nestled on top of the turret which most users feel is due to the high battery consumption rate of the product. Furthermore, the Weaver Tactical 1-5×24 scope depends on a 30mm one-piece tube and is complimented by multi-coated lenses to increase light transmission and give a bright display. This optic is Argon purged, protected from fogging, also reinforced internally to secure its delicate parts. If your 3-gun shooting would be in an intermediate range, then this model offers an amazing experience that is hard to beat by scopes in the same price bracket.


  • High light transmission for better visuals

  • Waterproof and fog proof


  • The reticle is not large enough on 1x magnification

9. Holosun HS403B Micro Red Dot Optic (2MOA)

Holosun HS403B Micro Red Dot Optic (2MOA)
[content-egg-block template=custom/all_offers_logo groups=”p9″]


  • Dimensions:
    6 x 6 x 4 Inches
  • Weight:
    4.3 Oz

Moving from fairly affordable scopes/red dots, we have arrived at the very affordable ones. A 3-gun scope should not cost you all of your life savings which is why Holosun HS403B here on our list. Based on other Holosun products that we’ve reviewed before, it is easy to tell that the company is becoming famous for producing good and decent red dots that do not siphon your bank savings. When put side-by-side to other models, you won’t see the need to pay the same (if not higher) price for optics that only lasts for 100 hours compared to the 50,000 hours you will get from this optics. For a long period of time, you don’t have to worry about changing the battery and in trying to change the battery, you realize how easy it is.


This is an improvement from the HS403A model where you have to unmount before replacing the battery. What about a touch of technology? Holosun has put a lot of effort into ensuring that users get the most out of this product by adding the shake-awake feature similar to the Sig Sauer Romeo5 red dot sight. Once this optic is not used for 8 hours, it powers down automatically and wakes up once it is set in motion. That’s cool for a low-cost sight and there’s no more reason to take calculated risks as this optic is durable, waterproof, as well as dustproof, and can be submerged underwater for half an hour up to 1 meter. Left to me, this is about all I would expect from a budget red dot sight.


  • Easy to replace the battery

  • Long-lasting battery (50,000 hours)

  • Waterproof and dustproof

  • Clear reticle

  • Comes with a high and low shooting profile mount


  • The screws used on the battery tray are small and difficult to screw in or out with the included tool

Last but not least is a 1-4×24 second focal plane rifle scope by Primary Arms. If you’ve not found the perfect 3-gun optic for you, don’t throw it away yet. There is more at the end of our review ladder than you would expect. Straightaway into the features of this lovely scope. It has a duplex center reticle and just because it is a budget scope does not mean that it lacks optic quality. Just as the manufacturers will say for this product, they really don’t use the word “value” as an euphemism for “junk”.


Eye relief for this scope is on the generous side with 3.5 to 4.9-inch relief which depends on the magnification that it is set to. This scope comes with 12 brightness settings with the control knob right to the side of the tube to illuminate the center dot for easy target acquisition. You may not see this coming but here, the Primary Arms 1-4×24 rifle scope is rated fog proof, waterproof, and fully multi-coated to brighten your display and give you clear visuals.

What To Consider When Buying The Best 3 Gun Scopes?

It is very expedient to take cognizance of some qualities when choosing a scope. Different shooters have varying tastes in shooting aids which makes their performance stand out. Here are some of the features/qualities you should watch out for when choosing a scope, especially for a 3-gun competition.


How close can you be to your target? The closer your target appears to you, the better your chances of accuracy. Compared to the naked eye, when you look through a scope of 9x magnification, you get to view your target 9 times the original size and in 3-gun shooting, you need to have a close view of the target to make a precise shot. While some scopes are fixed (you can’t change the magnification), others are variables (have more than one magnification). For example, Trijicon AccuPoint 1-6x is a variable scope with 1x to 6x magnification. If you will be shooting far distances, you need to consider this feature.

Objective Lens

The objective lens is the part of the scope that is responsible for the brightness and clarity of your display. With a bigger objective lens, you have a better view of your target. In the Trijicon AccuPoint 1-6x24mm riflescope, the number after the “x” (24mm) is the objective lens diameter. It is important to know what you need to take a clean shot. Choosing a suitable objective lens diameter can change your shooting for the best.

Scope Reticle

When you look through a scope, the crosshair that you see in the center of your lens is the reticle and it is chiefly important in making a choice scope. A good reticle makes shooting easier and some even go as far as estimating the target distance. I’m landing a clean shot on your target, you will need a well Illuminated reticle that is bright during the day and eye-catching in low or ambient light.


You may want to ask, “how does this affect my shooting?” A first focal plane (FFP) reticle will increase as you go up the magnification scale which is good for long-distance shooting but may obscure your view in situations of close-quarter engagement. The second focal plane (SFP) reticle on the other hand does not change with an increase in magnification and does not obscure your view at any range. Now, which is best for you?

Windage and Elevation

There are knobs on your scope to facilitate unparalleled shots. The windage turret adjusts the scope’s aim horizontally from left to right while the elevation turret makes the vertical adjustment from top to bottom. You don’t need further clarification to help you know how this could assist you in aiming better.

Eye Relief

Having enough distance between your eye and the optic lens of the scope keeps you confidently protected from taking the gun impact on your eye. For a rifle, you will need a scope with at least 3.5 to 4 inches eye relief. But if your rifle jerks back with force anytime you shoot, you should go for an eye relief much higher. With all of these said, let’s look straight into our top ten picks for the best 3-gun scopes.

Waterproof / Fogproof / Shockproof

The question of “can my scope withstand the rain?” Is no longer alien to the shooting community. It is good to have a fine scope but most assuring to have one that can survive any weather condition. A quality scope should be able to function well after taking some recoil and beating from the rain.


[ultimate-faqs include_category=’3-gun-scopes’]


There is certainly no more confusion for you having gone through this review and studied the features to look out for from a 3-gun scope Targets are precious and you don’t want to lose them all to inaccurate shots. The scope’s magnification should present you with enough visuals to make a clean shot. Know your effective range, shooting positions, and preference and find the ideal scope that will fit in with all of these requirements.


You will mostly find a larger eye relief scope to be very useful when it comes to 3-gun shooting. Somehow, these scopes help you improve your shooting accuracy without distortion of any sort when used consistently on appropriate magnification power in a 3-gun event. Summing it all up, 3-gun scopes are great shooting aids that help you improve your skill. From highly classy scopes to very affordable optics, 3-gun shooting is altogether memorable.
