I have wanted an HK 91 for over 30 years. In my opinion it is one of the best long guns ever made. It works great as an offensive, defensive, survival, hunting and assault weapon. Home defense is not a great idea unless you don't have neighbors within a mile and you live alone. (A .308 is a devastating weapon at close range and will shoot through doors and walls and it has a very long range.)
Anyway, after wanting one of these things for a long time I was not disappointed at all. I have not finished the "break in" period, but I have had no malfunctions so far. I purchased this particular model because of the welded top rail and the three forward rails. The lower forward rail is in use with a CAA bipod and a UTG folding grip w/ storage. The sights on the gun work great and are accurate. I have purchased an EOtech 552 calibrated for .308. The top rail is a must for this as it will allow use of items used on my 5.56 NATO rifles ... such as a magnifier and night vision.
As earlier stated, This weapon is very accurate with the stock sights. Though it does not say HK on the lower receiver, it is not a lesser quality weapon. In addition to being accurate it feels very solid and well built in my hands. It takes down without tools and is an easy to understand design. The carrier/bolt assembly is a bit strange, but in reassembly remember - turn clockwise! Once used to the procedure the gun can be taken down and reassembled in 3 minutes or less.
If you are used to AR's and bolt action rifles, there is a bit of a learning curve, but the PTR is a durable, solid, well made rifle. A great addition to my small collection.
