Best 3-Gun Scope – Top 5 Recommendations & Reviews 2023

From the beginning, the primary role of firearms was to serve as a battlefield tool. Later it was adopted by many civilian societies as a weapon for hunting, home protection and leisure shooting activities.

Along with firearms, the industry has also developed various gun equipment and accessories, resulting in an overflooded market with a massive selection of products.

After the ammunition, the telescopic sights are the essential part of firearms and, at the same time, probably the most confusing component of your firearm system.

In fact, there are myriads of gun optics, especially today when anyone in the gun business builds scopes with prices ranging from $20 to a couple of thousand bucks.

When speaking of gun optics, you should know that dozens of different scope types are purpose-built for various weapon platforms and applications.

One of the best grounds for testing optics is target shooting and shooting competitions because of the sheer volume of fired ammo in not-always-ideal conditions.

In the shooting sports arena, particularly demanding discipline is 3-Gun matches because of the various engagements that can be found in each tournament.

Compared to other shooting activities, the 3-Gun competitions are the fastest-growing shooting sport in the country.

Also known as multi-gun competition, it features fast-moving, practical or combat-style shooting at targets ranging from point-blank out to 600 or even 800 yards. You will shoot from positions that mimic defensive situations, such as behind barriers and around obstacles. It requires you to be in excellent physical fitness since you have to hit all targets as fast as possible, usually from non-standard stances. Unlike other competitive shooting disciplines, this sport requires proficiency with multiple guns.

As its name says, in a 3-gun competition, shooters use three types of firearms: a rifle, a pistol, and a shotgun. According to other shooting sports, the 3-gun discipline is divided into three primary divisions: Factory, Practical and Open.

By the rules, traditional iron sights and red dots are limited on pistols and shotguns, whereas rifles can have non-magnified or magnified optics.

Due to the dynamic nature of 3-gun sport, the optics for 3-gun have to be rugged and up to the practical, real-world scenarios. The best 3-gun scopes should be something other than niche-specific items but versatile ones that can work effectively on any terrain and condition.

As for the construction features, the optic for 3-Gun competition has to be lightweight and able to hold zero through some severe abuse.

Besides a compact and sleek design and a robust build to survive getting bumped around, a 3-gun scope should be made with high-quality glass to provide a bright and clear image.

Given that three-gun competitions are based on ranges with various targets at varying distances, your optics should have a manageable magnification and a limited field of view since these features could slow down your course speeds. It is advisable to look for the scopes with variable power and minimum magnification as close to 1x as possible.

Currently, the accepted scope standard for these fast-paced competitions comes in 1-6x and 1-8x configurations because these magnification settings allow aiming at a closer target and enable targeting at longer distances. The best 3-gun scopes come with an extended throw lever for quickly changing magnification.

Non-magnifying, second-focal-plane scopes are popular with Three-gun shooters as it works better at either end of the power spectrum of low-power scopes. Since the three-gun optics have to be ready for use in a wide variety of applications, the ranging reticles with multiple aiming points provide a tremendous advantage compared to simple Duplex or very complex Christmas tree-style reticles. Finally, the reticle with an illuminated center would be tremendous aid when shooting in low-lighting situations or with both eyes open at close range.

Compared to these vital features, other characteristics such as objective lens size, eye relief, or turret type are less critical and greatly depend on personal preference.

For this overview, we will introduce to you the best-magnified scopes for 3-gun competitions, while the non-magnified sights, including the red dots, holographic sights, and 1x prism scopes, we will leave for the other article.

Our Recommendations for 3-Gun Scope

Trijicon ACOG 3.5×35

There is no better way to start this guide than with the scope of legendary reputation, a Trijicon ACOG. There are a dozen variants of Trijicon Advanced Combat Optical Gunsight (ACOG) scope, but their main features are low power, fixed magnification and rugged durability.

While some Trijicon sights have a battery-powered LED-illuminated reticle, the flagship models like Trijicon ACOG 3.5×35 boasts fiber optic and Tritium dual-illuminated reticle.

This combat-proven optic is based on 30mm tubes made from high-quality forged aircraft-grade aluminum for extra strength. Though relatively compact, the ACOG 3.5×35 weighs 14 ounces, which is heavy compared to other optics.

Initially developed for combat weapons like the M16/M4 family, the Trijicon ACOG is the perfect choice for modern sporting rifles like the AR-15. For any accomplished 3 Gunner, the ACOG will balance a red dot scope and an L.P.V.O.

Along with fixed-power magnification, this ACOG sports a 35mm objective and fully multi-layer coated lenses that provide extraordinary clarity and bring you a bright and accurate sight picture.

Swarovski Z8i 1-8x24mm

At the beginning of this century, the variable power riflescopes with a low end at or near 1X were rare birds at the shooting ranges and hunting fields. Today, 1-4x and 1-6x scopes are more common things made by many optics producers. Still, selecting only top-of-the-range rifle scopes like Swarovski is heartily recommended if you want a more extensive zoom range (1-8x or 1-10x).

A couple of years ago, Swarovski Optik launched their Z8i line of scopes with a true 8 times zoom range, 30mm main tube and a high light transmission rate of incredibly 93 percent.

The Swarovski Z8i 1-8×24 is an illuminated L.P.V.O. (Low Power, Variable Optic) scope that is available with four reticle types placed in the second focal plane. While some reticles are suited to driven hunting, others are perfect for sport shooting and dynamic competitions like 3-gun matches.

For 3-gun competitors, particularly interesting is a FLEXCHANGE, the switchable 4A-IF reticle. In shortest, the 4A-IF is an illuminated circle around the intersection of a duplex reticle, allowing you to change from dot to circle-dot.

As a scope with a true 1X low-end, the Z8i 1-8×24 can be used with both eyes open, but this model also offers incredible versatility due to its exceptional field of view of 127.5 ft.

Like all scopes from this Austrian manufacturer, the lenses on this 1-8x L.P.V.O. are absolutely perfect, providing a super clear image and making them very usable for dusk and dawn hunting, even with a 24mm objective lens.

While the Razor 1-6x scope is available with M.O.A. or M.R.A.D. versions of its V.M.R., a traditional duplex reticle, there is one designed with the competitor in mind.
