FBI Block
Crystal clear synthetic ballistic gel calibrated to FBI BB Calibration Specs. See the complete wound profile on every shot: entry point, wound channel, expansion diameter, and final penetration depth, all visible without cutting the block apart.
Built to show what your round really does.
The FBI Block is a crystal-clear ballistic gel block built for handgun, pistol-caliber, and defensive ammunition testing. Calibrated to FBI BB Calibration Specs, it gives shooters, agencies, manufacturers, and creators a controlled way to see and compare terminal bullet behavior.
Use it to watch the entry point, penetration path, wound channel behavior, expansion, fragmentation, and final bullet position without cutting the block apart. When the gel is consistent, the difference you see is the round.
Each FBI Block measures 16L x 6W x 6H in, weighs 18 lb, includes a calibration card, and requires no refrigeration. Reusable up to 10x when properly remelted.
The consistent standard for showing bullet performance
Ammo brands, agencies, manufacturers, and creators use Clear Ballistics gel to make terminal performance visible, comparable, and easier to explain.
