Had this AR done in hydrographics a while back, skull pattern. It started chipping and peeling and I didn't like it. So decided to strip and do OD green moly resin. Here is the result on the receivers so far.
It's just standard 5.56/223.
BTW, I am an FFL and have parts and such in stock. If I don't have it, I can get it through my wholesalers. So if you guys need something, let me know. Doing it out of the house so I can sell cheaper than the gun shows and stores. This build is my gun show build just to show off.
