I witnessed this firsthand. After seeing it, I will not ever buy a pair.
Keep in mind busta, those tests are used as a guideline for ballistic eyewear. The rating is achieved after passing a few high-velocity ball-bearing tests. They were never shot by a BB!
Whether it's a product failure (ie: bad sample), or a flaw in the design that would be present in every sample, it doesn't matter. They failed, and that's totally unacceptable in my book.
The conditions were something like this:
-temperature ~75 F
-.25g BB, semi auto single shot
-AEG shooting ~310 fps with .20g BBs
-single shot fired at center of lens from ~8 inches, perpendicular to lens surface
The lens survived with only a small discoloration in the tint and a 1-2mm diameter indent on the inside of the lens. The discoloration was concentric in nature, and was approximately 5mm in diameter. The lens did it's job, in my opinion!
The problem lies in the frame.
Besides, these things are made in China!
