While challenging the misconception that semi-autos could not be accurate, the LR-308 remains on of the most popular target rifles, routinely shooting amazingly accurate groups and taking on some of North America's largest game animals. This 18" version offers much of the same accuracy of the LR-308, but in a configuration that 2lbs. lighter, making it a nice blend of benchrest and hunting rifle. The light contour barrel is button-rifled with 6 grooves, a lightweight gas block, and a custom Miculek compensator. With a gas-operated rotating bolt and a 8620 steel bolt carrier, the LR-308 is reliable and smooth-firing. The stock is a skeletonized A2 black Zytel Mil Spec with a trap door. The A2-style flattop upper receiver is extruded from 6066-T6 aluminum and the lower receiver is milled from a solid billet of 6061-T6 with an integral trigger guard and a standard two stage trigger. 1 in 10" twist. 19 + 1 capacity.
