NOt actually paint but Hydro dipped. MY first ever custom build about twenty years ago. G&P Magpul Sentry with Tightbore and tuned gearbox. Furniture was all bought on American E Bay and dipped by Lacota Industries the only company in the world with genuine MC film at the time. Built several more variations of it over the years in CQB length, mid length and rifle length, some with folding stocks, last one being a Mid Length ERG. Background is chinese copy of Crye Field vest, surprising quality for time, which I still have though sadly no longer fits me.
