The rifle’s TRO-XL Extended Free Float handguard offers a 38-slot top rail that aligns perfectly with the upper receiver’s top rail in both the horizontal and vertical axes. Machined from aerospace-grade aluminum alloy, it is octagonal in cross section, with the 3, 6 and 9 o’clock flats drilled and tapped for the addition of optional 2-inch or 9-inch TRO rail sections.
Furniture consists of a hand-filling Hogue overmolded rubber pistol grip, and an Operator CAR 6-position collapsible buttstock of RRA design. It features enhanced cheek welds, two quick-detach sling-swivel receptacles on each side, and an innovative rubber butt pad that slides off from the heel exposing two 5/8” diameter, 5.5” deep battery storage compartments. Overall length is 40.0” with the buttstock fully extended/36.5” collapsed, and empty weight without magazine is 7.8 pounds.
For reliability testing on our Salute Products steel-plate targets, we mounted a set of Magpul MBUS Pro steel backup sights on the top rail. In firing over 100 rounds, the LAR-6.8 X-Series ran just like we’ve come to expect from Rock River ARs—like a top, with no failures of any kind.
For accuracy testing from the bench at 100 yards, we mounted a Nightforce NXS Compact 2.5-10x42mm riflescope in a Nightforce one-piece mount. The only 6.8 ammo we had on hand for testing was Federal’s XM68GD 90-grain Bonded Soft Point, which we’ve always found to be a top performer. The Federal XM68GD and the LAR-6.8 X-1 were best buddies right out of the box, and the combination turned in an extraordinarily tight, best 3-shot group of 0.215″ center to center. The largest group printed 0.83″, with the average group measuring was 0.53″.
