I'm getting my spring shopping list in place and I'm trying to decide on my barrel options for my build. There is a nice Rainier arms 8.5" UltraMatch barrel that would go nicely with an adjustable SLR gas block, and there is the Noveske barrel that comes with a tuned gas block for subs, but not adjustable. Has anyone used either? Noveske block is pinned, and I'd get Rainier to pin the SLR.
