I have that same barrel but in 20 inch. I really like the barrel, Mine seems to be slightly under gased though so an adjustable gas block might not be needed, at least on mine. Like you said it couldn't hurt. The gas block on mine is a spikes if I remember correctly. I only have about 100 rounds thru it, a mix of 123 grain Hornady black and reloads ( 120 grain eld match with 26.3 grains of IMR8208XBR powder ) with no malfunctions. It seem to be accurate and recoil is very soft, its noticeably softer then a friends 18 inch mlgs. Very happy with it.
