NATO Block
Crystal clear synthetic ballistic gel calibrated to NATO 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 NATO Block is a crystal-clear ballistic gel block built for rifle, military-spec, and high-velocity ammunition testing. Calibrated to NATO 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 NATO 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.
