AR Shooters,

I use the spray can Duracoat on my hardware for the leather biz (making brass buckles subdued/black) Works pretty damn good with proper surface prep etc.

One of my projects is an AR, I did some function testing of my spare 20 and 30 rounders, some of them look like crap but work.

A 20 rounder was chosen for the test, check the photo out below. It was darn close to the looks of the 30 next to it. Easy application, a bit of baking (I just hang them next to the heater an use the IR temp gauge to keep them above 300F for a few minutes).

Good stuff with excellent results.
