PTR’s quality control is all over the place. My 9C ran right out of the box with my Flemming sear pack. I sent my 32K back to PTR the day after picking up for a warranty fix. The cocking handle was almost impossible to pull back. It’s baffling how it even left the factory in that condition. It took several trips to the range, but I finally got the 32K to run in FA. It turns into a bolt action gun with a suppressor attached. It won’t cycle even in semi.
