Pete, a friend of Gun Lab, was at the last Knob Creek show and picked up a PE-57 kit and repair section. He was nice enough to send me some pictures of the repair part and I thought I would add a few pictures of my AMT rifle to give you a comparison.
The first thing I have to say is that I am not beating up on the guy that made this repair section. This receiver is very complex and if made with the correct steel would be very difficult to press. With out having a progress stamping set up I think he did a descent job.
I also did not have the repair section here to measure.
I would like to hear from people that have used this repair section to build up a rifle.
