DMR means Designated Marksman Rifle. It is a sniper rifle with a designated marksman tasked with providing precise fire at medium distances. Unlike heavy sniper rifles, which have longer barrels and are designed for long-range shooting, DMR is designed to be more versatile and effective at medium distances, typically from 300 to 600 meters. DMR typically uses rifle cartridges (.308Win and others), meaning that the shooting is less affected by wind and gravity compared to more powerful sniper rifles. These weapons are often modified for accuracy, rate of fire, and ergonomics according to the individual needs of the shooter. 

Airsoft DMR

A DMR in the airsoft field is NOT an AK or M4 assault rifle with scope (as is often mistakenly seen at events), a DMR should therefore be a replica of a real rifle with larger calibers or a longer barrel equipped with an optical sight for long-range shooting. The exception would be real SPR rifles like the MK12, which can be classified as DMR rifles, although it is more of an assault rifle with a longer barrel with the ability to fire full-auto in emergency situations.

Several examples of Designated Marksman Rifle (DMR):

• M14 EBR (Enhanced Battle Rifle): A modernized version of the classic M14 rifle, which has been adapted into a DMR. Typically uses 7.62x51mm cartridges.
• SR-25: DMR based on the AR-10 platform. Manufactured in variants such as MK11 Mod 0 or M110 SASS (Semi-Automatic Sniper System).
• H&K PSG1: Sniper rifle designed by the German company Heckler & Koch, which was also used as a DMR for medium distances.
• SVD (Dragunov): Although often considered a heavy sniper rifle, some SVD variants are used as DMR at medium distances.
• HK417: German sniper system using the HK platform and used as a DMR.
• FN SCAR-H (Mk 17): SCAR-H in .308 Win/7.62x51mm heavy caliber version can be modified as a DMR.
• LMT MWS: Another modern sniper rifle that can serve as a DMR. Manufactured in various calibers.
