The U.S. Army introduces 5,000 to 6,000 new M110A1 Squad Designated Marksman Rifles (SDMR) for its group-level rifle scope shooters. The U.S. Army continues to use the 7.62mm x 51 calibre for its riflescopes.
The M110A1 SDMR is a semi-automatic G28E from the G28/HK417 family from Heckler & Koch. The weapons are to be manufactured in Oberndorf and then completely configured by the subsidiary HK USA with the SIG Sauer Tango 6 1-6×24 SDMR rifle scopes separately procured by the U.S. Army, Geissele assemblies and other attachments from a total of 12 companies based in the USA. They will then be delivered to the U.S. Army. Heckler & Koch will also provide spare parts, services and training for the soldiers.
The M110A1 will replace the M14 Enhanced Battle Rifle by 2022. The G28E already serves in a different configuration than the M110A1 Compact Semi Automatic Sniper System in the U.S. Army.
