UDMC S7 Caliber 7.62 NATO Rifles

  • • Bergara SS-410 Barrel for commercial models
  • • UDMC 4150 Barrel for military specification models
  • • Two Platforms: PVAR Gas Piston or DGIS Direct Impingement

United Defense Mfg Corp’s S7-PVAR and S7-DGIS are variants of the M110-SASS, Semi-Automatic Sniper System precision rifles chambered in the time-tested 7.62 NATO round (7.62 x 51mm) and designed to hit point targets up to 800 meters (MER). The S7 takes after the M110 battle rifle designed by Eugene Stoner. The S7 uses two action designs, the Direct Gas Impingement System (DGIS) and the patented Pneumatic Valve and Rod System (PVAR). The DGIS has a simpler design between the two as it has less parts and uses the hot gases coming from the gas port of the barrel and through a gas tube the hot gases are rammed into the bolt carrier group to cycle the round. The patented PVAR or Pneumatic Valve and Rod System is a “bare bones”, no frills and very simple designed gas and piston operating system that utilizes a combination of gas and mechanical energy for a more effective and reliable cycling of the weapon.

The PVAR design prevents hot and high-pressured gases from reaching the bolt assembly. This results in a cleaner and reliable operation, as well as minimal maintenance even in the most rugged environments such as jungles, deserts, snow and salt-water conditions. This means reduced cleaning time and overall longer rifle life span. The S7-PVAR’s simplified parts and mechanism allows reduced recoil and reduced muzzle rise, which enables the sniper to refocus instantly on the target for each and every round fired. Furthermore, the PVAR allows the sniper to select if he wants to use the rifle in bolt-action mode or self-loading (semi-automatic) mode. Both the PVAR and DGIS models use a one piece KeyMod picatinny rail handguard held securely only at the barrel extension which allows the barrel to “float” and preserve barrel harmonics while in battery.

This allows for greater accuracy and consistency. As designed, the barrel does not touch any part of the entire length of the handguard except at the barrel extension. For both the DGIS and PVAR, the barrel comes in different lengths: 14.5, 16, 18, 20, 22, 24 and 25 inches with a choice of either fixed or retractable buttstock. For special orders, UDMC can also produce the M110-CSASS or the “compact SASS”, with a retractable buttstock with a barrel length of 14.5 or 16 inches for use by the spotter. The non-glare, matte finish of the stainless steel barrel is also an alternative to the standard carbon steel in black manganese finish. While UDMC also produces the conventional DGIS system, the PVAR is more rugged than the conventional M110-SASS DGIS and most bolt-action precision rifles out there.
