This is in the early planning stages, however, have a desire to own an AR10! Something with long range capabilities. I know the AR10 comes in a variety of calibers, but mainly looking at .308. I thought of buying the parts here and there, but also considering the alternative to buy. I am looking at the Rock River Arms, LAR8 - Varmint A4 w/26" barrel. Rock River Arms: LAR-8 Varmint A4 I would like the Operator CAR Stock and the Advanced Half Quad Handgaurd! I think for the money, this would be hard to beat! Anyone own or shoot one? Impressions or thoughts? Would the 6" of barrel be beneficial to the .308 than the 20"? I understand the gain in FPS. Primary use: paper, rocks, maybe some critters if laws ever permit it.
