It hasn't been fired enough to assert reliability but it seems to run well with XM193 and PMAGs.
The first Faxon pencil barrel had to be exchanged because of a bad chamber but if as light as possible is the priority it may be worth the roulette.
My setup hasn’t hiccuped in over 500 rounds. When I tuned the gas block, I set it to fully cycle with PMC Bronze and a loose grip away from my shoulder. My range ammo usually alternates between PMC Bronze and Wolf Gold. I can go one or two clicks lower on the gas block for Wolf Gold if I wanted to.

The most light weight and low recoil AR I've EVER shot is the BCM 14.5 middy with KMR rail and their gunfighter comp. Nothing comes close at all.
Forget the gimmick parts. I wish I could loan my BCM middy out. It's unbelievable.

I agree with those that suggest finding other ways to cut ounces.
Geissele makes a nice rail, but they’re not what I consider to be lightweight.
I’ve got a couple BCM Magnesium/Aluminum KMRs that have held up well so far.

I am also in the camp of forget about low mass carrier gimmicks. Stick with what works, save weight at the rail and barrel.
G rails are not very light. Midwest makes a 12.65" rail that weighs 7.9 oz installed https://www.midwestindustriesinc.com...-ulw12.625.htm
I would rather save weight there than at the carrier.

Just use an AR-15 carrier then at least its reliable.
