Anybody Duracoat Their Guns ?

I had a duracoated FAL for a while, it was one heck of a nice finish on all of the surfaces. I wouldn't go with it on any bolt or carrier surfaces, but that is just my opinion.
I used to use one simialr to that in the Aust. Army....back in the day....it was a 7.62 x 51 Nato.....they were called an SLR L1A1 here.....nicknamed a Slur.......kicked like hell with the gas plug set to Zero.
