Buying Guide: How to Pick the Right 3-Gun Optic
Choosing the right scope for 3-gun competition can feel overwhelming, but it boils down to understanding the stages you’ll face. You need an optic that can handle close-range speed and mid-range precision, often on the same stage. I’ve found that the debate usually starts with one core question: variable power scope or a red dot sight?
For many shooters, a low-power variable optic (LPVO) in a 1-6x or 1-8x configuration is the top choice. The 1x setting gives you a red-dot-like experience for those hoser stages up close, while the magnification lets you confidently engage smaller targets out to 500 yards. The key feature to look for here is a true 1x magnification, meaning there’s no distortion or fish-eye effect—it should feel like you’re using a red dot. The illuminated reticle is non-negotiable for me; it allows for fast aiming on bright days and against dark backgrounds.
On the other hand, a red dot sight is the king of pure speed. With unlimited eye relief and a single, simple dot to put on target, they are unbeatable for close-quarters engagements. Their simplicity and light weight are huge advantages. The trade-off is precision at distance. Hitting a small plate at 300+ yards with a 2 MOA dot can be a real challenge. This is where magnifiers come in. Pairing a red dot with a flip-to-side 3x or 5x magnifier gives you a versatile two-in-one system that is very compelling.
Beyond the type of optic, you need to consider durability and features. These optics are going to be banged around, so look for robust construction, waterproofing, and a reputation for holding zero. The turrets are also important. I prefer exposed, tactile turrets for quick adjustments on the clock, but some shooters like capped turrets to prevent accidental bumps. Finally, don’t forget about the mount. A quality, single-piece mount is just as critical as the optic itself. It needs to be strong and hold its zero through all the recoil and movement.
FAQ
What is the best magnification range for a 3-gun scope?
For most 3-gun matches, a 1-6x or 1-8x low-power variable optic (LPVO) is the sweet spot. The 1x power is essential for fast, close-range targets, while the 6x or 8x magnification gives you enough clarity and precision for the majority of long-range shots you’ll encounter, typically out to 500 yards. It’s the most versatile option for the diverse challenges in a 3-gun competition.
Can I use a red dot sight for the entire 3-gun match?
You absolutely can, and many top shooters do. A red dot is the fastest option for close-range shooting. However, engaging small targets at longer distances becomes significantly harder. If you go this route, I strongly recommend pairing your red dot with a flip-to-side magnifier. This gives you the best of both worlds: the speed of a red dot up close and the added precision of magnification when you need it.
How important is an illuminated reticle?
In my experience, an illuminated reticle is a must-have. During a stage, you might be transitioning from a dark shadow into bright sunlight, or aiming at a dark target against a dark berm. A black reticle can get lost in those conditions. An illuminated center dot or circle allows you to maintain a consistent, fast aim point regardless of the lighting, shaving precious seconds off your time.
What does “true 1x” mean on an LPVO?
“True 1x” means that when the scope is set to its lowest power (1x), it provides a non-magnified, distortion-free view, very similar to looking through a red dot sight with both eyes open. Some cheaper scopes have a slight magnification, like 1.1x or 1.25x, which can cause eye strain or a slower sight picture. For the fastest close-range shooting, a true 1x is what you want.
Should I get a first or second focal plane scope for 3-gun?
For 3-gun, I almost always recommend a first focal plane (FFP) scope. In an FFP scope, the reticle grows and shrinks with the magnification. This means the holdover points on your reticle (like mil-dots or hash marks) are accurate at every magnification level. Since you’re constantly changing magnification during a stage, you can use those holds for a quick shot at any distance without having to do math in your head.
Are the expensive scopes really worth it for 3-gun?
This is a common question when looking at the 8 best scopes for 3-gun competition. The short answer is that you get what you pay for. Higher-priced optics from reputable brands offer superior glass clarity, brighter illumination, more robust construction, and better warranty support. They are built to withstand the abuse of competition and maintain zero reliably. While a budget optic might work, investing in a quality sight is investing in your confidence and performance on the clock.
