During the Global War on Terror, a new type of weapon system was developed. This weapon system is called the Designated Marksman Rifle or DMR. The DMR is a magazine-fed rifle that is operated in the semi-automatic mode of fire by expert marksmen, or DMs. The DM’s role within a U.S. infantry squad is to supply rapid, accurate fire on enemy targets out to 1,000 meters. The 7.62mm NATO DMR was adopted to enable military marksmen to use a more effective round to engage the enemy with precision at longer ranges, especially in difficult terrain. The DMR was also adopted to enable military marksmen to accurately deliver faster follow-up shots while engaging one or more targets on the battlefield. It should be noted that the effective range of the DMR is dependent on several factors, including the skill of the operator, the quality of the optics involved, and the ammunition used. The following are seven powerhouses that qualify as Designated Marksman Rifles.

The ArmaLite AR-10 was the first modern U.S.-made, semi-automatic, magazine-fed 7.62mm NATO rifle produced after the introduction of the M14. The ArmaLite AR-10 is a direct impingement rifle that is based on the design and operating features of the M16/M4. ArmaLite manufactures several carbine- and full-length 7.62mm NATO DMR-style rifles, including the new suppressor-ready ArmaLite AR-10 SuperSASS, which utilizes a 20-inch, triple-lapped, ceramic-coated stainless barrel, a free-floating rail system for use with BUIS or optics, an adjustable gas system, a Magpul PRS stock, a National Match trigger and
SR-25-type magazine compatibility. (armalite.com; 800-336-0184)

In addition to the select-fire FN SCAR Heavy MK17 carbine with a 16-inch barrel, the semi-automatic FN MK20 Sniper Support Rifle (SSR) can also be used as a Designated Marksman Rifle. The MK20 includes the following features: a chrome-lined, cold-hammer-forged, 20-inch barrel, an extended, monolithic hardcoat anodized upper receiver with a Picatinny rail system that has attachments at the three, six, nine and 12 o’clock positions, a side-folding retractable stock that is equipped with an adjustable cheekpad, a pistol grip, a reciprocating, ambidextrous charging handle and an adjustable single/two-stage trigger. The MK20 upper receiver can accommodate folding iron sights, various in-line day and night sniper optics and devices, and other accessories as required. The SSR is available in Flat Dark Earth, utilizes 10- and 20-round magazines and can be easily operated with a suppressor. (fnhusa.com; 703-288-3500)

The HK417 is a semi-auto or select-fire 7.62mm NATO DMR that is operated by a proprietary gas piston system. Heckler & Koch designed the HK417 to function reliably without parts failure or stoppages for 15,000 rounds and “little or no accuracy degradation.” The HK417 uses a free-floating quad-rail system that supports back-up iron sights, optics and other accessories. The rifle features ambidextrous controls (charging handle, safety and selector), a retractable buttstock with spare battery compartment, an optional suppressor, and 10- or 20-round proprietary magazines. The HK417 can also be easily configured to operate with a 12- or 16-inch barrel. HK is also making two similar DMRs, the MR762A1 and the G28. The MR762A1 is a semi-auto version of the HK417 with a 16.5-inch match barrel. The G28 is the DMR variant of the HK417 used by the German Army. (hk-usa.com; 706-568-1906)

The UK Ministry of Defense (MOD) selected the semi-automatic, magazine-fed, direct impingement-operated Lewis Machine & Tool LM308MWS rifle as their new DMR because this model proved to be consistently accurate, reliable and effective while engaging targets at CQB distances and beyond to 800 meters. After being adopted by the UK MOD, the LM308MWS became officially known as the L129A1. The L129A1 has a 16-inch blackened stainless steel 5R Ultra match barrel, a proprietary monolithic rail, a detachable, adjustable front post sight, a detachable, adjustable rear sight or a carry handle, a two-stage match trigger, a proprietary LMT SOPMOD buttstock, plastic 20-round PMAGs, a hardcoat anodized finish on all metal parts,
and it is available in black or tan. (lewismachine.net; 309-732-9527)
