Why didn't I pull the tube and seal it? In all candor, I couldn't be bothered. I was looking into a different issue at the time, and this was low priority. I've run plenty of systems without sealing the gas tubes, but never ran a setscrew gas block. My previous focus was on that, and that alone.
I'd like to convince myself that I left the gas tube alone so that I could determine if the carbon would eventually seal the leaks without help but, as I mentioned, I just didn't worry over it. No - wait! That's it... I'm conducting a longer term test on carbon build up. That's it. Carbon build up test.
I was taking apart and experimenting with 2 different guns for no good reason until I sold them and built a rifle with a Lilja barrel, it has not been apart since. If I can get my hands on a cut rifled barrel I can afford I'll do the same thing, build it right and leave it alone.
Mega upper (barrel fits very snuggly in this upper)
Lilja 17" AR740 profile, wasp profile behind gas block)
Young NM bolt carrier
PF bolt
Geissele Super gas block
Timney Trigger
Spikes LPK
Aero Precision lower (I really don't like it, but I will not take apart again!)
BCM carbine buffer tube and spring, H2 buffer
ALG Defense EMR M-LOK handguard (I believe this helps, they include shims and wrench extension to get the barrel torque perfect)
