Yea I guess the fire control parts don't need the lube, as long as there is lube on the pins which doesn't seem to go away I'm sure it will be just fine.
Yes, I added a "shot" of CLP down the buffer tube, not a tonne,

Like we're talking a half second spray here not even.
TDC there was a time when I bought a case of .223 federal and sat at the range and shot it all off in a couple hours. I had not added any more CLP at all, and the rifle functioned flawlessly. I had no stoppages or anything, I can only conclude that it was a well built rifle and my mags were very good as well. Point being though, I did notice alot of carbon build up on the end of the bolt itself when pulled out of the carrier. It was the kind of carbon that just won't come off no matter what cleaning agent you use.
I asked about a bolt scraper and found one online but have yet to buy it.
Would adding lube to the lube service port on the bolt carrier to lubricate the bolt every 100 rounds reduce fouling? Or does it just get so damn hot in there that it's impossible to reduce the fouling?
The rifle has about 2000 rounds through it and I've had no problems still, and the end of the bolt is just covered in crap that doesn't come off unless you have the scraper. I'm just wonder if this is going to have to get cleaned at some point, or is it something that I really shouldn't worry about?
