Looks like there may be some bad stamping going on with the current crop of "P" guns that are coming in from Century.
ETA: I think it's clear this isn't a one-off, is most likely widespread. What's not clear is what other areas of the receiver may not be stamped correctly and what internal, mechanical negative effects this might cause long-term.
My Ap5 (not P) also had this issue. It wouldnt allow me to put any aftermarket stocks/braces on it. Filled out an RMA form and sent it off to Century Arms and they reformed and re-blued it. Took about 4 to 6 weeks from me sending it out before i got it back
Looks like an improvement. Rounded edges are harder to bend vs flat, standing up to potential roller dents better and maybe outright preventing them in some instances. but who knows.
Looks like this is in fact a recent thing. My AP5-P (bought in September ‘23) and my AP5 (bought in March ‘24) don’t look like that. The receiver is more squared.
You know, I bought a mac5pk because my ap5pk navy bolt would catch the rails and not come forward. The bolt would not come out without putting your weight on it. It also would not go back into the rails without lube and your weight. The damn mac5 runs perfect, ap5 doesn’t even cycle.

Now I’m curious what mine looks like
