I'm looking at other barrels as well. I have 18" Grendel barrels coming out of my ears for some reason, all but one of them are new.
This one will need some way to choke the gas, as it has a .094" port diameter on a MLGS with 8 3/8" of dwell time in front of it.
I have another one with a similar set-up, a Satern 18" double fluted with MLGS, .094" gas port, that I'm having a local smith cut and re-thread with concentric threads in 5/8x24. The threads were off the bore axis on it, with no relief cut for muzzle devices that don't use crush washers. It will be a 17.5" when it's done.
