8.6 Blackout Chamber Gauge

Ensure every 8.6 Blackout round is ready before it reaches your rifle.

The Detroit Ammunition Company 8.6 Blackout Chamber Gauge is a precision 3D-printed inspection tool designed to verify the dimensional fit of loaded 8.6 Blackout cartridges. Ideal for reloaders, ammunition manufacturers, and quality control, it helps identify dimensional issues before ammunition is chambered.

Its integrated access slot provides a clear view of the cartridge as it seats in the gauge, allowing you to visually inspect the relationship between the case and the chamber profile during the inspection process. This added visibility makes it easier to spot potential sizing or loading issues that may not be as apparent in a fully enclosed gauge.

With a single gauge, you can quickly check:

• Brass sizing
• Headspace
• Bullet seating depth
• Crimp consistency
• Overall chamber fit

The open access slot also makes cartridge insertion and removal quick and easy.
