Failure To Feed on new AR-15… Scuff marks on charging handle(s)
The rifle will fire a round and eject it (most of the time) and everywhere says it’s undergassed. I lubricated it before firing the other day and it didn’t fix. I was wondering if the wear on these charging handles and the wear on the roof of the upper receiver had anything to do with it. The rifle is very stiff when i charge it but i chalked it up to the rifle being tight from the factory until the feeding issues. The buffer a carbine spring. Any help is much appreciated, and if i’m missing any important pictures or details let me know!! (The warhammer charging handle is the one ive been using and the other handle is stock)
[UPDATE]
I watched a couple youtube videos and it seems my gas key is not supposed to be getting any resistance from the tube when i slide in the BCG. This seems to be the issue. Any tips to fix it?
