BROWNELLS - Copper Anti-Seize, 8oz

This works very good for receivers and barrel nuts where you do not want them to lock up. It is a little hard to put on a thin coat with the built in brush, but I use a smaller brush to apply.

I used this anti seize for the first time on a particular AR build when assembling the barrel and upper receiver. It worked as advertised to allow for proper clocking of the barrel nut used in the assembly. Use sparingly no need to glob on it spreads out nicely.

The Brownells branded copper Anti-Seize is very good. It incorporates Coper verses graphite to completely eliminate the possibility of bimetallic (galvanic) corrosion at couple point. As with all Anti-Seize products it seems to multiply, use a disposable cover on your bench, and latex gloves, or you will be cleaning it up for weeks to come.
