Hi, fellas. This is a followup to a recent post I made about my new home-built AR. To recap, it's a Del-Ton 16" midlength complete upper with CMMG stripped lower, Palmetto LPK, and UTG milspec stock. Rear sight is Magpul MBUS.

After I completed the build, I disassembled the bolt carrier group, degreased with Break-Free Powder Blast, and regreased with a heavy coat of Mobil 1 full synthetic 5w30. I also put a patch saturated with break-free through the bore, following with a couple of dry patches. The bore was left mirror shiny.

I headed to the range this morning in 40ish degree temperatures. I brought the AR, a PMAG, 100 rounds of Federal 55gr .223 FMJ, and my spotting scope.

My first rounds hit about 4 inches low at 25 yards, with windage about dead on. After moving the front sight up 8 clicks (using a front sight adjustment kit consisting of a .223 cartridge and a pen), I was grouping everything about where I wanted it.

After about 22 rds I moved the target out to 100 yards. At this point, I mostly practiced standing with rifle at low ready, and firing as soon as I could raise the rifle and get a sight picture. Did OK at this, mostly getting minute-of-chest groups. I also shot from the bench a bit, with my best string a bit over an inch.

Through this, all rounds fed and ejected well. Hopefully this trend continues. I really like the Mobil 1 as a lubricant. I expected some dryness on the BCG after 100 shots (some fired pretty rapidly), but when I inspected it, it was still wet as when it started. The Mobil 1 seems to stick pretty well, and really makes the action slick.
