16" .308 barrel came in today, Nathan - VERY IMPRESSIVE! I like it alot. Damn nice barrel, and fine work. I picked up your gas block, and grabbed the gas tube, too, just so everything would get here in the same box, and I wouldn't have to strip any parts off the other barrel.
Did a quick check of the gas block - gas block perfectly centered over the barrel gas port, with the block against the barrel shoulder. Gas port diameter is 0.080", midlength gas system.
Very nice work, Nathan, very nice. <thumbsup>
