They are, I have both. My HK is like a 76 model and the PTR is just a more modern and better made version of the same rifle. Shoots better, cycles smoother, and fits tighter. Maybe its because my HK is old as I didn't know it when it was new but it is in pristine shape. The PTR is a better rifle. Its like comparing an old Colt AR15 from the 70s to a brand new S&W or something.I believe it might have been Nonliberal that thinks these are better made than the HK91. They are battle rifles and very reliable. In my opinion, they're the best value going in 308.
