It's easy. Buy a little miter saw at Harbor Freight for 25 bucks. Chop some fired 5.56 cases to length and run em through your full length die after lubing of course. Trim to length. Very easy. I have done hundreds when BLK brass was hard to find.
Rick Rankin is the Gunsmith on Garden in Pensacola. He's been in the same shop for 50+ years. Great guy, extremely professional, and a perfectionist. If he works on your gun it'll be perfect when you get it back.
