Brownells Half Tank Bluing System Burner Assembly

The Brownells Half Tank Bluing System Burner Assembly is a complete heat source solution for gunsmiths and armorers who want to set up efficient hot-bluing operations. This assembly gives you everything except the orifices—the gas control and delivery components needed to run a half-tank bluing rig reliably. Whether you're refinishing bolt carrier groups, small parts, or touch-up work, having the right burner setup matters when precision heating is part of the job.

What you get is two 25-inch half-tank burners, each capable of producing an 18-inch flame—enough heat output for controlled blue tanks without the footprint of full-size equipment. The dual-burner design lets you balance heat distribution across your tank, and the flat-face mixers give you independent control over each burner's flame. A regulator with quick disconnect makes setup and breakdown faster, while the braided gas hose T assembly handles connections between your tank and both burners. Mounting hardware is included so you can secure everything to your bluing tank frame.

One key detail: this assembly ships without orifices, which means you'll need to order them separately based on your fuel source. If you're running natural gas, you'll want the #32 orifice. For propane (LP), grab the #51. Having the right orifice is essential—it ensures your fuel and air mixture is dialed in correctly for optimal flame and temperature control.

This is a modular, purpose-built approach to bluing heat. You're not jerry-rigging a kitchen stove or wrestling with improvised setups—you're using equipment designed specifically for the task. If you run a home shop, operate a small armorer business, or do regular refinishing work, a proper burner assembly transforms your bluing operation from frustrating to functional.

Frequently Asked Questions

Do I need to buy orifices separately?

Yes. This burner assembly does not include orifices. You'll need to order the correct one based on your fuel: #32 Natural Gas orifice (Brownells #082-032-032) or #51 LP orifice (Brownells #082-032-051). Installing the right orifice ensures proper fuel-air mixing and flame quality.

Can I use this for both natural gas and propane?

The burner assembly itself is compatible with both fuel types, but you must swap the orifice depending on which fuel you're using. You cannot run both fuels through the same orifice—each fuel requires its own orifice part number.

What's not included in this assembly?

This assembly does not include the orifices (as noted above) or a gas tank. You'll provide your own tank and purchase the appropriate orifice for your fuel source. Everything else needed to connect and control the burners is in the box.

Is this a complete bluing system or just the burner part?

This is the burner assembly only—the heat source and control components. You'll need a bluing tank (the steel vessel that holds your work and bluing salts) to complete a functional system. This assembly handles the flame generation and regulation.
