For those who run factory loaded pistol rounds thru a DI upper, how clean is it?
Assuming we're taking good domestic production ammo like Sig Elite. I guess I'm asking cause I remember reading threads in the early days of DI PCCs and I saw some say that the gas tube would foul quickly, not sure if that was suppressed or not. |

I haven't done anything to clean my gas tube and I don't recall if I have even taken my bolt out of my BCG in several thousand rounds. I have an Echo II, so my .45 has seen some rounds. When I recently changed out the upper, I noticed nothing out of the ordinary with the gas tube and simply cleaned the upper with some brake cleaner and compressed air. My .223 weapons that I run more often with a can see much more fouling. I do tend to do a quick wipe down of the external bolt surfaces and a cursory wipe of the internals about every other range trip. On any AR platform I usually apply fresh CLP to the usual places right before heading to the range, when I can remember to do it, whether I clean it or not. |
Let me put my meat on your grill.
