Hello,
Sounds as if I have a Pope-barrel. I will confirm by removing the stock.
I have attached a couple of pics. One reflects the "lobe" being held out under spring tension but not cocking the bolt. It will cock the bolt if in just the right position.

"Reincarnated" Thanks for the neighborly treatment. The same goes for all persons who have given feedback. You may want to checkout the link I mentioned earlier. I think that would be another Pope barrel configuration confirmed. You can rest assured I will be shooting this rifle. What is a GPR?
