Heckler & Koch Defense Inc., Ashburn, Virginia, was awarded a $33,500,000 modification to contract W15QKN-16-D-0051 for the Compact Semi-Automatic Sniper Systems (CSASS) and the Squad Designated Marksman Rifle (SDMR). Bids were solicited via the internet with one received. Work locations and funding will be determined with each order, with an estimated completion date of March 16, 2022. U.S. Army Contracting Command, New Jersey, is the contracting activity.
In April 2016 Heckler & Koch confirmed that a lighter version of the G28 (HK417) had won the U.S. Army’s Compact Semi-Automatic Sniper System (CSASS) contract to replace the M110 Semi-Automatic Sniper System. It is designated as the M110A1 and uses an aluminum upper receiver instead of steel to meet weight requirements, weighing 8.4 lb (3.8 kg) unloaded and reaching some 15 lb (6.8 kg) loaded and with accessories,the M110A1 features a Geissele M-LOK rail handguard, Schmidt & Bender 3–20×50 PM II Ultra Short telescopic sight, Geissele optic mount, OSS SRM6 suppressor, 6-9 Harris bipod and mount, and a collapsible stock with adjustable comb.
In March 2018, the Army announced that a version of the G28/M110A1 would be issued to infantry squads as the service’s standard Squad Designated Marksman Rifle (SDMR). Issuing a 7.62×51mm NATO SDMR is meant to increase individual squads’ ability to defeat enemy body armor that standard 5.56×45mm NATO rounds cannot penetrate. Unlike the sniper configuration, the SDMR model will be equipped with a different buttstock and barrel twist than the CSASS model. The marksman version is fitted with a simpler SIG TANGO6 1-6×24 telescopic sight and it fires M80A1 Enhanced Performance Rounds or XM1158 Advanced Armor Piercing Rounds rather than sniper rounds.
