M110A1 SDMR

The M110A1 SDMR is a 7.62x51mm NATO semi-automatic designated marksman rifle manufactured by Heckler & Koch for the United States Army as part of the Compact Semi-Automatic Sniper System (CSASS) program. Based on the HK G28 platform, which itself is derived from the HK417, the M110A1 features an adjustable gas block with a suppressor-ready muzzle device, a Geissele M-LOK handguard, and the SIG Sauer TANGO6 1-6x24 optic. It delivers enhanced accuracy and range over standard M4 carbines while being lighter and more maneuverable than the M110 SASS it replaces. The M110A1 bridges the gap between infantry riflemen and dedicated sniper teams by providing squad-level precision fire capability.
