The U.S. Army also uses the M14 EBR-RI, being created and updated by the Weapons Product Support Integration Directorate of the TACOM Life Cycle Management Command at the Keith L. Ware Test Facility in Rock Island Arsenal, Illinois; having fielded approximately 5,000 units by mid-2010.

[11] In March 2018, the Army announced that a version of the HK G28, which had already been selected to replace the M110 SASS, would be issued as the service's standard SDMR.

Issuing a 7.62 mm SDMR is meant to increase individual squads' ability to defeat enemy body armor that standard 5.56×45mm rounds cannot penetrate.

A Kydex hand guard and M68 CCO are also added, though they are almost always replaced with a vertical foregrip and magnifying scope for better handling and for use in a designated marksman role.

[citation needed] A Wind Talker suppressor can be mounted on the DC Vortex flash hider,[14] though the U.S. military did not adopt one to active service.

Sage International had some involvement in the decision of whether to invest approximately $120,000 in an injection mold incorporating rail attachments into the design or machine the replacement stock from a solid billet of aluminum.

The Mk 14 has been criticised for being too heavy, at 14 pounds (6.4 kg) when loaded with a 20-round magazine, with most of this weight being at the front of the weapon, making it difficult to aim.

[22] Philippine arms company FERFRANS has created their version of the Mk 14 Mod 0 called the FERFRANS SOPMOD M14/M1A Enhanced Battle Rifle, which uses a Sage International M14/M1A EBR Tactical Stock System aluminum chassis, an M4 buttstock, and a GRSC M4-62 General Purpose Combat Recticle.
