What is a DMR?
DMR stands for “designated marksman rifle.” The concept of the dedicated marksman (DM) has a military origin, where these shooters are equipped to bridge the gap between regular infantrymen and long-range snipers. A well-outfitted DM can engage medium to long-range targets, yet has versatile equipment that also works for CQB when necessary.
DMRs are typically semi-automatic rifles and are usually chambered in .308 or 5.56. DMRs are often weapons based on either the AR-15 or AR-10 platforms (like the Sig 716).
The optic on a DMR must be lightweight, durable, and versatile enough for rapid, close range target acquisition, while offering enough precision for targets out to 600 yards.
How to Choose a DMR Scope?
Whether engaging enemies in battle or running maneuvers on an airsoft field, the designated marksman fills a crucial role. DMs require very specific features in an optic. Here are just a few key characteristics that help a scope perform well in this position.
Magnification
Magnification is often the first thing shooters look at when purchasing a new scope. DMs often have to pull off precision shots at the limits of their rifle’s capabilities. They also need an optic that allows for rapid target acquisition during close-range engagements. Basically, a DMR scope needs to do it all.
A variable power scope can be a godsend on a DMR. Excessive magnification can be a hindrance, so look for an LPVO (low power variable optic) that maxes out at 8-9x. A scope with a true 1x at the lowest end will prove its worth during CQB situations.
Reticle
Finding the right reticle for a DMR can be tricky. A mil dot or BDC reticle is helpful on targets past 300 yards. However, these reticles can feel cluttered when shooting close range targets, which can result in slower target acquisition. For a DMR, you’ll need a reticle that balances long-range precision with rapid target acquisition.
FOV
A scope with a wide FOV (field of view), especially at lower magnification, is necessary for tracking moving targets. An ample FOV is also useful when transitioning between multiple targets.
Optical Quality
Quality glass is crucial for a DMR scope. Low quality glass often results in fish-eye effect or other aberrations, especially on the high end of the magnification range. Without a crisp, clear sight picture, making quick, accurate shots could be a problem, especially in low light conditions.
For best results, look for a scope with high-density, extra low dispersion (ED) glass and fully multi-coated lenses.
Durability
Durability is important in a DMR scope, because these optics often see rough use in the field. Look for an optic made from durable, aircraft-grade aluminum that is o-ring sealed. An optic that is waterproof and shockproof should hold up in even the harshest conditions.

When you do need to dial in on long-range shots, the ATACR has a ZeroStop elevation adjustment that allows for a quick, easy return to zero.
The ATACR also features a tough, tank-like housing crafted from aircraft-grade aluminum. It also features stunning image clarity thanks to its ED glass and fully multi-coated lenses.
