36 SADEFENSEJOURNAL.COM LEFT: The DPMS GII SASS is equipped with a free floated quad rail allowing users to set it up as they see fit. BELOW: A Schmidt & Bender 5-20x50 PM II Ultra Short was mounted on the GII SASS via Recknagel quick release mount. Schmidt & Bender has become the optic of first choice for many elite units with scopes available for precision long range accuracy as well enhancing other types of weapon platforms. ABOVE: While designed for long range accuracy and reliability in mind, the DPMS GII SASS was also proofed with Meopta MeoSight in close range scenarios.
DPMS GII SASS.308 Win. AR Rifle and other types of supported fire if needed. Some of the precision tactical rifles coming on line today reflect more of target shooting heritage than tactical weighing over 16 pounds. The GII SASS’s 10 pound weight translates into a rifle that can be carried afield without fatiguing the marksman and is easier to adapt to non-standard firing positions even offhand if needed. The 18- inch medium profile barrel is a solid compromise balancing weight, performance, and field handling for the tactical marksman. The GII SASS had no problems with shifting points of aim even when firing a full magazine of twenty aimed rounds in relatively rapid fashion. A Schmidt & Bender (S&B) 5-20x50 PM II Ultra Short was mounted on the GII SASS via a Recknagel quick release mount. The S&B had a Tremor 2 reticle. Further tactical modification of the GII SASS into a lowlight/dark role is satisfied by mounting an American Technologies Network ATN PS22 Night Vision device in front of the Schmidt & Bender scope. This multi-use ability keeps day scope constantly zeroed, yet allows for quick adaptation during a night mission. This eliminates the need for a separate dedicated weapon system exclusive to night vision tasks or having to constantly remove day optics from a rifle and replacing with a NVD. The PM II Ultra Short design had just this application in mind with its design. The ATN PS22 serves as a force multiplier when employed on the GII SASS. The forend also has side rails for mounting IR illuminators used in conjunction with the NVD device or intense tactical white lights if NV is not used. The GII SASS reflects modern trends of utilizing night vision with night vision devices easily mounted. Various .308 Win. loadings from Black Hills Ammunition, Federal, Winchester and Hornady provided the basis of accuracy tests. The Black Hills Match loads tested consisted of 168 grain Match bullets. The Federal chambering was the venerable 168 grain Match load. 168 grain TAP from Hornady and 168 grain Match from Winchester was also tested. The GII SASS’s 18-inch barrel with the 168 grain loads clocked 2,550 feet per second. As to be expected with quality ammunition, velocity figures within the different loads deviated very little from round to round. This is critical for predicable long range accuracy. The GII SASS shot all the premium 168 grain loads tested into 1 MOA or better at 100 yards. Many will scoff at this as typical gun writer fluff. Obviously, the best ammunition brands and loads where utilized. Black Hills Ammunition, Federal, Winchester, and Hornady are industry leaders, which is what this type of rifle deserves to wring out its full potential. The testing was done off a bench supported by Harris bipod and Champion shooting bags. The Federal 168 grain Match, Winchester 168 grain Match, and BHA 168 grain Match produced the best 100 yard average with all producing slightly over 5/8 inch averages. The accuracy figures are based on firing 3 three-round groups and averaging group sizes. Another sign of an accurate, dependable rifle is how cold bore zeros compare over time and if the point of aim shifts after a few rounds heat up the barrel. The DPMS GII SASS showed no shifts in point of aim and cold bore zeros produced fine groups when overlaid together. Not much time was spent at the 100 yard range. After verifying innate accuracy from the bench, field tests were performed at Echo Valley Training Center (EVTC). Echo Valley Training Center is properly set-up to handle extensive test firing of a precision tactical rifle like the GII SASS. In conjunction with the individual training bays, EVTC features multi-stepped target berms that are strewn with reactive steel targets, fluid drained automobiles, and moving targets at ranges varying from 150 yards out to 350 yards. Echo Valley Training Center is further enhanced by the existence of prepared firing positions. This allows for more realistic prone and “dug-in” trench-style firing points consisting of concrete culverts turned on end and buried. These firing positions and target arrangements are ideal for all types of SADEFENSEJOURNAL.COM 37
