Best Scope For Colt LE6920: Scope Or Sight!

Colt LE6920 is a sibling of the combat expert brother M4. Both of them share a lot of similarities. Just like the bigger brother, this one is quite picky when it comes to scope as well. Not all scopes are suitable for a burst-firing gun.

While trying to find the best scopes for Colt LE6920, I was shocked that there weren’t many suggestions revolving around this gun.

Then I said to myself, “Fine, I will do it myself”. Having previous experience with scopes and guns, it wasn’t easy for me to hunt down a suitable candidate for this gun. What are those candidates then? Let’s find out.

Things To Know While Buying An Optic For LE6920?

Build Quality. Burst rifles tend to have a different recoil pattern. That can hit your scope with sudden movements. Which can lead to scope dysfunction. We don’t want that to happen. To prevent from that ever happening, you should look for a scope that is capable of taking recoil hits with ease.

Magnification. While browsing for a sight for your LE6920, the first thing that will come to your mind is the zooming power of the sight. You wouldn’t enjoy a scope that wouldn’t offer a good magnification. While you don’t need the most powerful scope in the world, a medium-range scope will suffice.

Lens Quality. If we are going for budget sights, then lens quality matters a lot. Most of the time budget sights don’t have good quality coating on them. Look for something that has a decent bit of coating.

Warranty related to glass-like objects matter more than we care for. You don’t want a broken crossbow hanging over your gun and hindering your performance. Try to take something from a company that offers a decent warranty.

Best Optics For Colt LE6920 – [Editor’s Picks]

1. Vortex Strike Eagle 1-6X24mm Rifle Scope


It’s a good scope that is versatile enough to run an M4 without an issue and is decent for other types of rifles as well. Heck, you can try hooking it up on a sniper rifle for all Vortex care. We have featured this in many of our previous reviews as well. You can try some of them to have an idea of why this scope is so good. It’s a bang for the budget riflescope.

Can it Strike?

It’s a super versatile scope that you can keep even after drifting apart from your M4 or Colt. It can be used in AR-15s as well. Besides these, you are also getting great build quality from Vortex and its praiseworthy optics.

Lens Quality

Vortex’s lenses are so good that other manufacturers buy lenses from them. When it comes to their own scopes, they won’t slack. Stock lenses on this scope are fully multi-coated with multiple layers of chemicals that brighten up the glass. It’s also scratch-resistant to some degree.

Build Quality

When I said it was versatile, I meant that. It’s built like a tank. Some recoil hits won’t do anything to it. Your reticle setting or magnification won’t change from a bit of the gun’s recoil.

The inside of the scope is also nitrogen-purged. It will keep it clean from moisture and fogging issues. Water can’t get inside of the scope either. All of the holes of this scope are sealed with O-rings. That prevents from water going inside or staying near the rings.

Bad Sides?

There can’t be all good and sugarcoating all over, right? Of course not. We are not getting paid for this so we can’t be biased honestly.

One of the things that bugged me a lot about this scope is the focal plane. I know it’s quite cheap. Yet, all the features this scope has to offer will perform a lot better in the first focal plane.

2. Aimpoint PRO Red Dot Reflex Sight with QRP2 Mount


Red dots are fancy as well. The design of this sight is quite mesmerizing. Wouldn’t be surprised if you guys mistake it for a 2/3x scope instead of a reflex sight.

Huge Battery Life

The claim from Aim Point is insane, to say the least. Up to 3 years of battery life from the included battery. That’s a bold claim. I cannot vouch for the 3-year claim. What I can vouch for is, that it will outlast any scope that uses a battery for sure.

Night Vision Compatible

It comes with four-night vision-compatible settings. As the sight took more of a scope approach, the prism inside can put up solid performance.

Parallax Free

Now that’s an amazing thing. You don’t need to worry about parallax at all. Super cool Aim Point. Impressed.

Bad Things!

The night vision mode isn’t the best. If you are taking a sight for night vision, I would say go for night vision riflescopes instead. Otherwise, solid performing sight all around.

3. Leupold VX-Freedom 3-9X40 Rifle Scope


Leupold is not a new name to anyone. If you have searched about any riflescopes, you have seen the name Leupold appear at least once. The one we have here is the 3-9x40mm variant of Freedom. It’s a medium-range riflescope that supports Colt LE6920.

The Good Things?

All of the scopes featured in this list have to offer something worthwhile for you. Why else would you want to buy these optics?

Most of the scopes that support M4 also support LE6920. VX Freedom is one of them. It offers Leupold’s latest technology and their famous lens.

Build Quality

What impressed me is how well-built this optic is. I know it’s expected from Leupold to have a well-built scope. Considering the price point of this scope, it’s quite sturdy. It’s 100% waterproof.

The inside of this optic is also nitrogen-purged to make it fogproof. If you are wondering about how the recoil pattern will affect this scope. Don’t worry. It won’t affect the scope a bit.

Lens Quality

On top of a fully multi-coated lens, you are also getting a scope with Leupold’s twilight light management system. It’s a system that can use low light and balance between low/bright light.

What I am trying to say is, that no matter what’s the condition (besides pitch dark), the scope will always show you clear and vivid pictures. A big win in my opinion.

Suitable For Extreme Condition

It’s surprising to see a scope like this is resistant again cold temperatures. Usually, they tend to give up on life if you take them near a snow mountain or something similar. With this one, you don’t need to worry about that. Your gun may freeze but the scope won’t. Suffering from success.

Tell Me The Cons Already

The main con for me was the fixed parallax. You couldn’t do anything about that. Low-profile turrets aren’t meant for everyone either. They are good without gloves, but they are not that good with thick gloves on.

4. Vortex Optics SPARC Gen II Red Dot Sight


Vortex Sparc Red Dot sight is second generation red dot sight from Vortex. We all know how good Vortex riflescopes are. How about their sights? Let’s find out.

Tell Me About The Good Stuff

We are not here to make a drug deal but I will tell you about the good stuff. And you will know where to find the good stuff as well. Corny jokes aside, it’s a red dot with tons of features. Let’s talk about some of those features.

Bright Red Dot Reticle

A lot of red dot sights have issues showing the dot in broad daylight. Thankfully, we don’t have any of those here. To take full advantage of the sight, Vortex recommends you keep both eyes open. With this, you can cover more area and hit the target while looking at the broad terrain as well.

Windage And Elevation

To change either of those, you will need to remove the turret cap and adjust it according to your needs.

Build Quality

The build quality of this sight is quite good. It’s one of the best sights for Colt LE6920 without any doubt. You can fit it on the rail of that gun without any issues. It will fit them snuggly and stay there. It’s shockproof as well. Don’t worry about the recoil hit.

Cons Exist!

It’s a good red dot sight but it uses a AAA battery to power up the red dot illumination. This will add a little bit of weight and an inconvenience. If you run out of batteries in the middle of a hunt, you will be quite angry. Keep some batteries on your pocket as a backup.

5. Bushnell 4.5-18X40 Riflescope with DZ 223 Reticle


The last optic for Colt LE6920 in our list is from Bushnell. Most of you probably already heard of them by now. They are a company that makes scopes for all ranges of budgets and guns. The one here is one of the best optics for Colt LE6920 without a single doubt.

Why Bushnell 4.5-18×40?

What makes the Bushnell 4.5-18×40 stand out from the rest of the contestants? Bushnell 4.5-18x is a mid-range riflescope that will complement your Colt LE6920. We all know it’s a close brother of the M4 rifle.

M4 is quite a good performer in the mid-range arena. Why not pair it with a scope that is capable of doing just that? After all, we are looking for the best scope for Colt 6920 here, aren’t we?


This scope features Bushnell’s all-new multi-turret setting. It features BDC turrets for all popular chamberings. The turrets on this is exposed. Which allows you to use them easily even with your gloves on. Every time they will be precise and you can set them up at any magnification.

Quicker Magnification Change

This scope comes with two PCL. They are there to help you aim faster and precisely at any magnification. If the installed PCL looks smaller to you and you are having trouble using that, use the longer pole included in the package.

It’s one of the best sights for your Colt L6920 that’s for sure. It’s not super expensive either. A win-win situation.

Bad Sides Of The Bushnell 4.5-18×40?

While the objective lens of this scope is quite big, it doesn’t gather enough light during the low-light condition. That can bother a lot of hunters and tactical shooters.

6. Vortex Optics Spitfire 1X Prism Scope


It’s not a red dot sight. It has a DRT reticle and 1x magnification. Red dot sights don’t have any magnification and the crosshair is a red dot.

Is It Any Good?

I had my doubts as well. 1x scopes aren’t the most powerful thing in the world. While talking about magnification is pointless, some other things aren’t.

Adjustable Reticle Focus

You can adjust the focus of the reticle by moving the ring around the objective lens. It will act like setting focus on a riflescope. Neat.

Dual Ring Reticle

There is a small ring around the red dot crosshair. It’s designed for instant combat mode. The dual ring design makes the eye focus instantly on the red dot crosshair. Making your reflex faster. The reticle is etched on the prism directly. There is 0 chance of this thing moving around.

Any Bad Thing!

With batteries come responsibilities. It will run on any AAA batteries. And you need the battery to illuminate the reticle. Illuminated reticle is a game changer so we can’t compromise there. You might or might not run out of battery in the middle of something. It’s better to carry some around. Like a weirdo, I always do that. You never know.

7. Trijicon TR20 AccuPoint 3-9X40 Riflescopes


Trijicon AccuPoint 3-9×40 is a mid-range riflescope. It’s capable of magnifying and base magnification is enough for tactical shooting.

Why We Recommend It?

It’s a good scope for the money and the reticle on this is quite good as well. The scope is balanced in terms of weight and specification. Whoever designed this, had to put some thoughts behind it.

Optics Quality

Lenses are the sole carrier of a scope. If they are not good, the scope is not good. Thankfully, that’s not the case here. I was surprised by the clarity of these lenses. At 9x magnification there is no chromatic aberration or blurriness on the edge.

Build Quality

Like all other scopes on the list, it’s constructed from high-quality aluminum. The same sort of aluminum that is also used in the Navy and Aircraft making.

It’s shockproof and waterproof. While there is no O-ring isolation to make 100% sure of that. It won’t be affected unless you decide to submerge it for a couple of hours. Inside of the scope is also nitrogen purged. Making you tension-free on a cold day.

Here Comes Johnny (Cons)

The scope offers 3 different reticles to choose from. All of them are good in their regard. But a newbie might get confused. The choosing process is not beginner-friendly.

Frequently ASKED Questions

Is A Sight Mandatory For Colt LE6920?

Why can’t I go full John Wick and use the iron sight only? If he can do that I can too, right? Maybe, you can. But most of us definitely can’t. A sight will improve your vision game and make you more accurate. If you are getting good accuracy, what’s not to like?

Red Dot Sight vs Rifle Scope

Red dot sights offer no magnification but is quite accurate. Depending on the red dot you are buying, you might get a different color of dot or a cross axis crosshair.
