U.S made clone of the German G3, or in this case the civilian model, the HK91. Note the CETME wood handguard, stock and magazine. These parts are interchangeable since the CETME is the precursor to the G3. However the muzzle device is aftermarket. PTR is a nice affordable way of getting into roller locked firearms, at a fraction of the cost of an actual HK rifle or avoiding the possible quality control issues from Century Arms build
