Best 3-Gun Scope – Top 10 Best 3-Gun Scopes Review

Compared to traditional shooting disciplines like skeet or bullseye shooting,  one can best describe 3-Gun competitions as dynamic, fast-moving, practical, or combat-style shooting. As its name says, 3-Gun matches involve using three different types of firearms: a pistol, rifle, and shotgun.

Our Picks for 3-Gun Scope

Though you can find throughout local 3-Gun clubs many different classifications with different rules and regulations, there are generally three categories used as a standard across the country.

These are Factory, Tactical and an Open Division category.  Each of them has different limiting factors on what gear, guns, calibers, ammo capacity and optics are allowed.

In the early days of 3-Gun competitions, red dots, holographic sights, and 1x prism scopes were only allowed devices since the 3-gun stages were adapted.  Later, with more proficiency and mastery demonstrated by the shooters, the organizers were forced to extend ranges, making them more distant and smaller.

Usually, 3-Gun stages include various targets set up at different distances requiring from competitors not only excellent shooting skills but also flexible optics that will work well in all kinds of situations.

Rather than the usual red dot or 1-4X scope typical to stages in the 1980s and ’90s, today, new shooters mostly start with the 1-6x or 1-8x optics.

As the 3-Gun matches usually encompass long-range precision shooting and ultra-close situations, some classes allow shooters to use a high-powered rifle scope and a second optic for the close targets.

While the Low Power Variable Optic (LPVO) is almost an ideal scope for the primary sight, for the second optic, most shooters choose a red-dot reflex sight.

In the next part, we’ll try to present you with 10 top-of-the-line scopes and few moderately priced models that offer excellent usability for the price.

Having a scope that is adjustable between 5 and 500 yards is a too demanding task for any newcomers to 3-Gun shooting matches.

There is no best scope for everything so that one might choose the LPVO scope, the other will opt for old school, choosing a simple red dot, while the third might combine both of them in 3-Gun classes where it is allowed.
