I'm still happy with the shake and spray duracoat. It's holding up with no wear. Prep was just degreasing. Coated my SS barrel just fine. Just mask the block area, or mount the block and mask it.
Please down a few for me boys and enjoy the holiday. Will be on high alert all too soon. Duty calls. To all those on duty, stay diligent, stay on your toes, and above all, make it home.
First thing you should know is you don't have an AR 10. This seems trivial to most, but we correct that here because it is incorrect and will cause you a great many headaches being new. You have a 308ar. AR10 is the designation for the Armalite brand rifle which has proprietary parts which will not work with some of your parts. Other parts are interchangeable, but we can get to that after.
