Ateup, did you get your FTE malfunction diagnosed and/or fixed?
New build, failure to extract spent shell, charging handle hard to pull back

I don't know what I'm doing wrong, but they all just seem to work right out of the gate, like all my other AR15 builds.
I just haven't seen FTExtract that I can recall, come to think of it. Could be my memory going to crap too though, so who knows...
OP: What's your buffer and recoil spring set-up?
What's your gas port diameter?
A 20" should have a RLGS and a .094" port.
When you say "out 1 turn" on the Adjustable Gas Block, does that mean 1 turn from closed? Is so, there's your problem-nowhere near enough gas. Keep opening it until you get lock back on the magazine, then open it another half turn or more, considering weather conditions and their effects on the gas system when they get warmer or colder. Colder will require more gas, hot will require less.
Based on what I've read here, if I ever do try an adjustable gas block, I think I'll start out wide open and work down from there.

Quality barrel, proper gas port, standard gas block - no problems. Minor fine tuning can be done with buffer weights and or springsSticks
Catchy sig line here.
