A designated marksman rifle (DMR) fills the gap in the effective range between infantry rifles and sniper rifles. A designated marksman (DM) uses an optic-enhanced semi-automatic rifle to engage targets between 330 and 660 yards.
A DMR must allow rapid target acquisition while providing accurate holdover and windage corrections, and precise zero adjustments. Check out the list below for more information on finding the best DMR scope for you.
The DMR platform isn’t just for military and law enforcement. Perhaps you are a firearm enthusiast who wants to replicate this type of rifle for range shooting or even hunting. Or maybe you are an airsoft player who wants to take up the designated marksman position for your squad. However you plan to use your DMR, the need for a good scope remains consistent.
The AR-15 and AR-10 platforms are perfect for building a DMR. Rifles chambered in 5.56 are a great option for a DMR while 7.62 caliber rifles such as the Sig 716 are also great choices.
You’ve probably heard the saying that a team is only as fast as the slowest teammate. Something similar is very true about rifles; they are only as good as the scope mounted on them. Even if you build the best rifle in the world, it still needs a high-quality scope to be accurate, precise, and reliable at any sort of useful range.

Things to Consider When Choosing DMR Scopes
There are a few things to really keep in mind when shopping for a DMR scope.
Rapid Target Acquisition
In high-pressure situations, target acquisition must take place quickly. Some scopes allow for this better than others. Factors that contribute to rapid target acquisition are light transmission, reticle design, and field of view (FOV).
The more light that is transmitted through a scope, the brighter and clearer the sight picture. Most modern scopes are at least acceptable in this area. However, some are better than others. Look for a scope with ED glass and fully multi-coated lenses for best results.
Reticle design also plays a role. A simple reticle makes target acquisition less confusing because there isn’t much to clutter up the sight picture. However, this factor is a bit of a balancing act as a simple reticle design can sacrifice precision at longer ranges.
Field of view is the other important factor. A generous FOV makes it easier to pick up targets and zero in on them.
Accurate Holdover and Windage Estimations
Unlike snipers, designated marksmen won’t have as much time to make on-the-fly scope adjustments. A scope that allows shooters to adjust to estimated holdover and windage corrections is extremely important. The ability to lead moving targets is also vital.
This mostly comes down to reticle design and a DM’s familiarity with that design. There are plenty of reticle designs to choose from, so make sure to pick one you are willing to learn how to use effectively.
Because DMs often have to engage targets at distance, windage and holdovers may need to be dialed using the scope’s turrets. Look for locking turrets that provide precise incremental clicks, feature a knurled or textured design for easy gripping, and have a zero-reset feature.

The capped turrets feature precise click values of .250 MOA and are finger adjustable. This scope is equipped with a MOAR reticle that allows shooters to make holdover and windage estimations quickly and easily with 1 MOA elevation and windage markers and .140 MOA lines. The reticle also has a floating center crosshair that makes target acquisition a breeze while the side parallax adjustment keeps the image sharp.
2 CVLIFE 3-9×40 Optics R4 Reticle Crosshair Scope
The Optics R4 scope from CVLIFE is an excellent option for airsoft DMRs. This lightweight scope fits into any budget and comes with Picatinny rail mounting rings. With scratch-resistant and fully multi-coated lenses, the Optics R4 boasts an impressive 90% light transmission rate.

7 Monstrum S330P 3X Prism Scope
While the designated marksman is typically firing in the 330-660 yard range, sometimes they need to engage targets in close quarters combat (CQB). The Monstrum S330P 3x Prism Scope strikes a good balance between CQB effectiveness while remaining useful out to 500 yards. The S330P features a glass prism optical system which provides a more compact, maneuverable design than traditional refracting systems.
This prism scope’s reticle is visible with or without illumination, giving it a decided advantage over red dot sights. The illuminated circle dot reticle can be adjusted to red or green with various brightness settings.
