I've got a DDM4 V5. Mid Length gas system. This is a my first AR and I've noticed some brown coloring around the gas block on the front. I'm not sure if this is normal or not? D.D has a good warranty and is this something worth sending back? No mechanical issues or failures. Probably has 600 rds through it. Thanks for the help!!

When I first built my gun, I noticed a lot of brown fouling on the barrel behind the gas block. After my gun reached the ~300 round count, my weapon stopped functioning. The gas system wasn't working and my AR15 became a bolt-action rifle. I ended up taking the entire upper assembly apart and reassembling it. I paid special attention to securing my gas block properly (I have a YHM set-screw mounted low-profile gas block).
I've reached 1000 on my rounds count and I see no more brown fouling and I haven't had a single malfunction. Most of what I've shot through my gun is Wolf WPA. Just wanted to share my experience with the brown fouling. Hopefully, you won't encounter the same issues I had. Cheers :) |
