Tightly wrap the extension around the aluminum foil cathode.Create an extension of aluminum foil, in similar fashion to the ring, long enough to protrude to the top of your tub or tray.
The ring should be large enough to surround the receiver by about 3"" to 5"". Create a tightly wrapped, round ring approximately 1"" thick, using aluminum foil.Leave enough wire to safely protrude above the tub or tray. Wrap a loop of aluminum wire tightly around the lower receiver.This will help to produce a better finish. OPTIONAL: Surround the container in ice to lower the solution's temperature.Fill a clean polyethylene tray or tub with sulfuric acid and distilled water.

It must be completed free of surface contaminants, grease, and oil. Current is then applied using a battery charger and the oxidation process occurs, coating the raw lower with an anodized finish! You must wear gloves, a face mask, and proper eye, face, and body protection during this entire process: This process involves creating a cathode (negatively charged aluminum foil) and an anode (positively charged lower receiver), and submersing the pair in a solution of sulfuric acid and distilled water. Battery charger or adequate power source.The steps below are intended to be a summary of the process, and should not be followed step-by-step by an inexperienced person. Protective gloves, clothing, and eye wear must be used at all times. Interacting with sulfuric poses an extreme risk of serious injury or death if not handled appropriately. Extreme precaution must be used at all times. WARNING: This process requires the use of sulfuric acid.
This is not a Type III hardcoat anodized finish, but this finish can be easily dyed at home to obtain the same look, color, and texture. It's incredibly durable, corrosion resistant, and it's sexy. The anodizing process described below will yield a "sulfuric acid anodized" finish. Anodizing protects an 80 lower from the environment quite well. With the right tools (and serious safety precautions) you can anodize your raw 80 lower at home. Anodizing is an electro-chemical process. Let's begin! Anodizing Your Raw 80 LowerĪnodizing is what the majority of standard AR-15 80% lower receivers are finished with. By the end of this post, we think you'll know which coating is best for your build.
