GC Patrol Shield - ASTM Verified Rifle Rated Shields

Third-Party verified edge-shot protection and real-world durability sets high industry expectations for Law Enforcement safety.

Being the first and only company to achieve ASTM verification of rifle and shotgun protection is significant validation of our superior ballistic protection technology, providing assurance to LEOs.”

— Mox Weber, President GC USA

PROVIDENCE, RI, UNITED STATES, December 19, 2025 /EINPresswire.com/ -- Graphene Composites USA (GC USA), a leading innovator in ballistic protection, announced today that its ultralight GC Patrol Shield^® has become the first and only rifle-rated ballistic shield to pass and receive third-party verification for rifle and shotgun rounds under the ASTM E3347-25 standard (Standard Specification for Ballistic-Resistant Shields Used by Law Enforcement Officers).

This milestone represents a significant advancement in officer protection and provides law enforcement agencies with independently verified, enhanced ballistic resistance that exceeds previous industry standards. Third-Party verified edge-shot protection and real-world durability at half the weight of conventional shields sets high industry expectations for Law Enforcement safety.

The ASTM E3347-25 test result confirms that GC Patrol Shield successfully protects against ASTM-Shield-RF1 and ASTM-Shield-SG threats, including 7.62 x 51mm M80, 7.62 x 39mm MSC, 5.56 x 45mm M193, and 12 Gauge Shotgun 1 oz slug rounds, while maintaining structural integrity under the most demanding real-world conditions. SEI, affiliated with ASTM and responsible for verifying ASTM standard compliance, has verified the GC Patrol Shield test result.

Raising the Bar for Ballistic Shield Testing
This standard is intended to replace the forty-year-old NIJ 0108.01 generic standard for ballistic resistant materials, where ballistic shields were self-certified by manufacturers and contained significant testing limitations whereby a shield had to withstand five widely spaced shots, viewports were not tested, and no third-party verification was available.

The ASTM E3347 standard addresses these critical gaps by requiring that shields are tested by third-party, ISO-qualified laboratories that verify shields perform under ‘real-world’ conditions and threats that affect shield performance, including:

● Extreme environmental conditioning (hot, cold, and water submersion cycles)
● Viewport testing
● Edge shot testing
● Cluster shot testing
● Angled shot testing

"Being the first and only company to achieve ASTM verification of rifle and shotgun protection with our GC Patrol Shield, is significant validation of our superior ballistic protection technology" said Mox Weber, President, GC USA. "The ability of our ultralight shield to absorb higher-caliber rounds in adverse conditions while retaining integrity, provides law enforcement agencies with independently verified assurance that GC Patrol Shield will perform when officers need it most. We are incredibly proud of this achievement."

Superior Protection Without the Weight Penalty
GC Patrol Shield achieves ASTM E3347 verification while weighing significantly less than traditional ballistic shields, making it far less taxing for officers to carry and deploy during extended operations or rapid response situations.
