Best 3 Gun Scope for Competitions

If you’re involved in competition shooting, you may be interested to know what the best 3-Gun Competition scope is. Stick around for this guide as we highlight the 3-Gun Competition, what you would be looking for in a good competition scope, and our top five picks for the best 3-Gun scopes. 

The 3-Gun Competition

The 3-Gun competition is possibly the fastest growing shooting competition out there. It consists of a structure of different courses in which you make your way through the course shooting three different weapons, a rifle, pistol, and shotgun, at different stages.

You will shoot both long range and close range targets from different positions. The goal is to hit the most targets in the least amount of time with each firearm. It is a super exciting and fast-paced sport, and constantly changing as no two matches run exactly the same courses. Although you can have optics on your other competing arms, we will focus and compare scopes for the tactical rifle sections of the course.

The scope magnification power options that you choose for this competition are extremely important. The targets are never the same. Some are long-range and some are close-range. Some are stationary and some are moving targets. 

The best option scope for this competition would be a low variable power range scope. The most popular choice is a 1x to 6x power. 1X is no magnification, and works greatest for quick target acquisition and using both eyes open in the event of tactical style targets that are close-range and moving. 6X power is powerful enough to get a good shot out to 800 to 1000 yards for a long-range shoot, if you even needed to go that far out. 

For the most part, these lower variable power range scopes are also going to be much lighter weight than a scope with crazy high power range features because they require less glass optical layers. 


The 3-Gun is all about fast pace, so getting on target quickly is key. Some people use a red dot sight, but as far as a scope goes, you want something with multiple aiming points at can be adjusted easily between long-range and close-range. 

Mil-dot or hash mark, or BDC reticles are probably the best options. These reticles have multiple aiming points set up on a vertical plane and are great for putting the right aiming point at the correct distances for greater accuracy and to reduce the guess factor. Many people also find an illuminated reticle to be very helpful.  The only thing to keep in mind about a BDC reticle is that it is very specific to the bullet caliber, load and shooting conditions that it was zeroed at. 

Eye Relief

Eye relief is the distance that your eye has to be from the ocular lens in order to see a full view of your image through the scope. Ideally, you want a nice long eye relief so that you do not get cracked in the face by the scope with the recoil.  Plus a longer eye relief assists you in those both eyes open scenarios. 

A larger eye box is another important feature that you want for your scope. The larger the eye box the bigger range of positions your head can be in and still see through the scope. This is very important when you’re shooting rapidly and moving around for different targets. 

Focal Plane

For the 3-Gun Competition, a second focal plane scope is much better than a first focal plane scope. First focal plane is where the reticle size changes with the increase or decrease in magnification and second focal plane always stays the same size. 

You would want a second focal plane that stays the same size because with first focal plane scopes on lower power magnification settings the reticle is very hard to see, and at higher power settings the reticle can overpower and block out the target.

  • Superior Quality Lenses: Multi-coated lenses provide superior clarity and light gathering capabilities with zero distortion
  • Battery-Free Illumination: Fiber optic technology automatically adjusts the brightness level and contrast of the reticle aiming point to available light conditions and a tritium phosphor lamp...
  • Aircraft-Grade Aluminum Housing: All-weather rugged construction protects against the toughest elements
  • Second Focal Plane Reticle: Reticle size remains constant as magnification increases which provides a more exact aiming point at higher magnifications
  • Zero Forward Emission: The illuminated reticle doesn't project any illumination from the objective lens

The Trijicon AccuPoint is a 1-6x powered rifle scope that has several different reticle pattern choices available and has a non-battery powered illuminated reticle made with fiber optics for all ambient light conditions and tritium for low or no light conditions. 

The Trijicon AccuPoint is a second focal plane reticle scope, which is the preferred style for the 3-Gun competition. An illumination dial allows you to control the brightness level of your fiber optic aiming point, and when dialed up to 6x power the MOA cross-hair reticle can be used as your own personal BDC reticle. 

Customers of this scope have commented that it is a true 1x optic and that the fiber optic is much brighter than the battery powered aiming points of some of the other scopes out there. They love the clear glass and say that the performance is absolutely the best!

Negatively, it seems that when people have issues with this scope it has something to do with the reticle. Some report that you can’t see the green dot at all when it’s in tritium. Other say that the fiber optic is good only if the light’s shining directly above the gun, otherwise you can’t see it at all. 

Positives Recap for This Product

  • 1-6x power magnification
  • several reticle pattern choices
  • non-battery powered tritium and fiber optic illumination
  • second focal plane
  • brightness control dial
  • true 1x optic

Negatives Recap for This Product

Commonly Asked Questions

What is the max distance I’d be shooting for the 3-Gun? – More than likely you would not be shooting out much further than 500-600 yards, though I have heard of someone have to do a 980-yard shot. Most of the shooting will be close to mid-range. This is why most people go with 1x-6x power variation scopes, so you can quickly move and acquire new targets at very close range, but can go out to those longer shots as needed. 


I hope this guide has been helpful to you in learning a little bit about the 3-Gun competition and what would be the best scopes for it. If nothing else, hopefully, you have learned a bit more about what features you would want to look for when shopping for a good 3-Gun scope. 

I whatever you choose, remember that speed and accuracy are the keys to this competition, so get a scope, get out there and start plinking. The 3-Gun is a fast-paced sport that welcomes newbies at shooting as well, so if you’re not a third generation marksmen, that’s OK. Most of these folks will help you out to success, and before you know it, your grand-kids will be second generation marksmen! Happy shooting!
