I wanted a mandible for my helmet, and saw one dirt cheap on Amazon, that came with goggles that attached to it.
I figured the goggles would be shite, with no rating specified in the listing, but thought what the hell, the mandible is exactly what I want, if the goggles suck it doesn't matter.
Fixed it all onto the helmet, and fired some test shots at it from my QRF, at 20 feet, hopping.25s.
To my surprise the goggles held up just fine, a few scratches but no buckling or dents.
The mandible, however.....
My own fault for buying cheap shit.
