Problem with red dot mount

[TERRIBLE]

I have a Sar 109t. Holosun HS503G red dot. The bolt that goes through mount and picitinny, snapped on first shot fired. Optic came with high and low mounts. I thought it was a rare defective bolt. I took bolt , from low mount, and reassembled. Once again bolt snapped on first shot. Bolt was not overly tight.I was hoping someone would be able to advise me.

Replace with a quality bolt. Chinesium can be top notch, or dogshit. Sounds like you got the later.

Replace with grade 8 or 12 hardware.

Did you happen to use a INCH POUND TORQUE SCREW DRIVER? You'd be surprised how much force you can exert with a screwdriver & it don't seem like much.

The second one , l did. I have a few years experience. Just had never seen this happen. Fix pretty obvious, l guess. Thanks for the input all.
