I am selling my Rock River Arms LAR-15 EOP 16" upper in 223/5.56. It will come with a vortex diamondback 3-12x40 scope and a set of 1/2" risers to get other scopes up higher. The only reason I am selling is because I need a flat top for my intended purpose. The upper is $750 for everything. If you'd rather have the whole rifle I would sell it for $1150.
