Stripped screw out of the box - Aimtech Shotgun Receiver Saddle Mount for Benelli

I got a ASM-23 scope mount for my Benelli nova. Looks great and feels like it is high quality. But the rear screw is stripped and the mount is stripped at the rear position. Either it came from the factory this way or optics planet sold me a return or something. I don’t doubt it came this way from the factory considering the phone number and email Adress on the instructions are no longer available. Super sketchy. Luckily I’m pretty much a machinist so I can fix it myself. The actual mount does feel really nice tho. Doesn’t look like the picture at all.
