The ISBI Return Fire Door Glass represents ISBI's commitment to law Enforcement in Armored technology for Patrol Cars. The goal of our design is superior ballistic protection with original appearance and operation.

Return Fire is a revolutionary concept that allows rounds to exit the glass and respond to the threat while protecting the officer. Patented technology includes a soft polycarbonate inner layer to pass the bullet without deformation and with minimal loss in speed. The round then penetrates the glass, which causes deformation but with velocity.
