Hey everyone. So I am having problems with my AR-10. It is a .308 and it is a DPMS LR 308 platform. It has a low profile non adjustable gas block. So, I have to use forward assist after every round or I get a light primer strike and it won't fire. When I chamber the first round by pulling the bolt back, it shoots fine but if the action is open after the last shot and I close the bolt by pushing the bolt release lever, it will not shoot unless I use forward assist. I have tried a stronger buffer spring but then it would be too stiff and it wouldn't grab a new round from the magazine. I cleaned my BCG thoroughly and have lube in all the right places. My next step is to replace the gas rings. Any other ideas?
