Product Description:

The first on our list of Best Scope For Colt LE6920 is Aimpoint PRO Reflex Sight. As you are aware that Aimpoint is well known for its Quality and performance. This sight is top-of-the-line by Aimpoint and will offer you unrivaled performance every time you use it.

Robust Construction:

The first thing that is worth mentioning is its robust construction. It is built from high-strength aluminum material to withstand any physical abuse in the field. Its aluminum casing provides protection against vibrations, shock, and internal fogging.

The quality of the glass is also very good and hard surface coatings on the glass make it scratch resistant. Its lenses are not only scratch resistant but also water-repellent which allows you to use it even in a wet environment. 

Wide Range of Brightness Settings:

This one of the best scope for Colt LE6920 comes with an array of brightness settings to suit any shooting need in the field. There are 10 brightness levels, 4 of them are night vision compatible while the other 6 are for daylight use. One of these 6 daylight brightness levels is extra bright which can be used in bright sunlight conditions.

Amazing Battery Life:

The Aimpoint PRO red dot reflex sight is powered by a single DL1/3N battery. This battery allows you to use it for up to 30000 hours of constant operation. It means you can use it for over 3 years constantly before replacing it. 

QPR2 Mount & Spacer:

It comes with the all necessary hardware to install it on the Colt LE6920. Its ready-to-mount kit includes a QPR2 mount and a removable spacer to adjust this Aimpoint PRO red dot reflex sight with ease. 

Flip-up Lens Covers:

This optic is equipped with flip-up lens covers for both front and rear lenses. These lens covers are made with thermoplastic elastomer material and have a non-glare finish. The front lens cap is solid black and the rear one is transparent. 

In an emergency situation, these lens protective covers allow you to shoot with both covers closed and both eyes open. The last highlight found on this sight is its compatibility to work with all generations of ARD (Anti Reflection Devices).


The only con I have found in this Colt LE6920 sight is that it is a little heavier than other red dot reflex sights on the market.

Product Description:

Almost every rifle lover is familiar with the Leupold VX-Freedom 3-9×40 Scope. The upgraded version of this VX-Freedom series addresses the needs of serious shooters. It has some truly spectacular specs and features therefore we decided to put it on the list.

Latest Optical System:

The advanced and innovative optical system of this one of the best scope for Colt LE6920 ensures true light transmission and glare reduction for uncompromising resolution and clarity. There will be no distortion even at the extended magnification ranges.

Rugged and Lightweight:

The Leupold VX-Freedom 3-9×40 is a lightweight scope. Despite being lightweight, it has rugged construction and the ability to endure the abuse of rifles in the field easily. The aluminum alloy housing offers excellent durability and ruggedness to get the job done every time perfectly.

Second Focal Plane Reticle: 

Another wonderful attribute of this Leupold scope is its most popular, second focal plane Duplex reticle. It is one of the most popular reticles around the globe. The Duplex reticle was invented in 1962 for fast target acquisition even in the low light environment. 

The reticle stays in the second focal plane. Its size remains the same while the target size grows when you increase the magnification power and shrinks when power decreases. 

Scratch Resistance:

Scratch-resistant lenses are also a talking point for this best scope for Colt LE6920. The lenses are treated with military standards hard coatings to offer you the guaranteed protection of the exterior lenses. Its lenses remain crystal clear even after years of hard use.

Weather Proof Scope: 

The advanced technology of the Leupold utilizes gasses and modern methods of sealing to make this scope 100% weatherproof. So it can be used in extreme temperatures, elevation changes, and heavy shocks without worry. 


One particular area in which I wish Leupold VX-Freedom would do better is its illumination. This VX Freedom series is non-illuminated. It could add more value if it is illuminated. So we hope that the coming upgraded version of this series will be illuminated.
