Garand Thumb, investigates the real-world performance of different levels of "bulletproof" glass featuring ballistic glass manufacturer Armitech. The testing begins with lower-level UL-rated glass, where a Level 6 panel, rated for 9mm, successfully stops handgun rounds like .22, 9mm, and the more powerful 10mm. They then move to a Level 7 piece of glass, which is rated for five shots of 5.56mm.

Diles46 got his gameplay footage taken from Black Site of American Milsim available on his YouTube Channel... "Sometimes in airsoft or milsim, even plain glass windows can become bulletproof. When you throw some airsoft grenades into the mix, things really get interesting! Filmed at American Milsim's Black Site in Alabama, 2017.
