AR15 vs Kevlar Helmet @500 yards. With M855A1 5.56.
This video tests the penetration capability of M855A1 5.56 ammunition fired from an AR-15 platform at a Kevlar helmet from 500 yards. The test demonstrates that while the helmet was significantly damaged, the projectile did not fully penetrate, suggesting a potential for it to stop rounds at this distance, though material fragmentation was substantial.
