The Rock River Arms Elite Operator is one of their line of LAR-08 rifles, and it has several upgraded features not found on their standard LAR-08 rifles. The Elite Operator wears a sixteen inch chrome-moly heavy barrel. The rifle has a 308/7.62x51mm chamber, and will function with either cartridge. The barrel is rifled one turn in ten inches, and the muzzle is fitted with a Smith Enterprises Vortex flash suppressor. The barrel is threaded 5/8x24 threads per inch (TPI), to accept standard sound suppressors, muzzle brakes, flash suppressors, and other muzzle devices.
The Elite Operator uses Rock River LAR-08 polymer magazines, FAL metric magazines, and L1A1 inch-pattern mags. However, those military magazines do vary somewhat, and I tried none in the Elite Operator. However, the LAR-08 magazine supplied worked perfectly, feeding flawlessly. Three, five, and ten-round magazines are also available from Rock River, if desired.
The Elite Operator weighed in at nine and three-quarters pounds on my scale, with the empty twenty-round mag in place. The overall length varies from 36.75 to 39.75 inches, depending upon the position of the adjustable buttstock.
While Rock River guarantees the Elite Operator to group within one and one-half minutes of angle at one hundred yards, the sample rifle did considerably better than that, with select loads. Accuracy varied from groups as large as two and one quarter inches, using Lake City military ball ammo, to as small as five-eighths of an inch, with the Hornady and Buffalo Bore match loads.
