Thanks Molon.
Random observation, I was a bit surprised to see how short the gas system is on some of those barrels, given their length.

A true "lightweight" or "pencil" barrel tapers from .67" to .60" behind the gas block, is .625" at the gas block, and is .57" in front of the gas block with a small flare before the gas block and before the muzzle threads. Anything smaller than a .75" or "Govt" barrel could be called lightweight though.

16" lightweight Colt barrel assembly in-stock in case you go through with your plan (which I think is a good one). Will need the crush washer and FH as they're not included.

I am a fan of A1ish inspired profiles on carbines for some. The OP's rifle could very well be one of those. For 16" barrels, I would definitely look at a longer than carbine gas system, something in the range of mid to KAC length.
Na, just a simple life.
FWIW, the M14 barrel tapers from .74" to .63" before the gas cylinder and then is .60" in front of the gas cylinder. So really, not much thicker than an M16A1 barrel. There probably aren't many 7.62 AR barrels that are that light though. The MK17 SCAR has a pretty light profile but I don't know the dimensions.
