Our ultralight GC Patrol Shield® is the first and only rifle-rated ballistic shield to achieve third-party verification under the new ASTM E3347-25 standard for rifle and shotgun threat, marking a major advancement in law enforcement protection.
This confirms the shield’s ability to defeat multiple rifle and shotgun threats while maintaining structural integrity under extreme conditions, delivering independently verified performance beyond previous industry benchmarks.
The new ASTM E3347-25 standard addresses these critical gaps by requiring third-party testing of real world conditions, including:
This achievement sets a new benchmark for ballistic shield performance and gives agencies greater confidence in deploying lighter, more effective protection in high-risk operations.

Its simple, innovative design and practical application addresses the unique challenges faced by patrol officers with its balance of simplicity, durability and comprehensive protection.

As GC Patrol Shield becomes the first and only rifle shield verified to pass the new ASTM E3347-25 standard “Standard Specification for Ballistic-Resistant Shields Used by Law Enforcement Officers, Police1 has featured an in-depth look at this milestone.
This includes an expert assessment from Ron Tetreau, who brings over 30 years of law enforcement and military experience.
Tetreau’s evaluation focused on real-world operational advantages, including the shield’s edge shot protection, reduced weight for extended carry, full-body coverage for kneeling officers, and the option for camera systems to maintain situational awareness without compromising ballistic integrity.
“As a former SWAT commander and active shooter instructor, and with my military experience, I would say the GC Patrol Shield meets and even surpasses some of the steel and ceramic shields that are out there, and at only half the weight.”
