Nice.. I plan on building one with WOA barrel soon... Any advantage to having the 18 over the 16 inch barrel?
I think the primary difference would be a little extra velocity. I've got a 16 inch WOA barrel on my 6.8 that shoots sub-moa for 5 shot groups. It loves the SSA 85 gr TSX the best (sub-moa .6-.9 moa on the last trip), the SSA 110 gr +100 gr Accubonds shoot 1-1.5 moa (very limited # of groups, 4 total). The SSA 115 gr OTM showed a lot of promise too but I shot all of that up using a milspec trigger. I'd have 3-4 shots touching and then screw up my pull and there goes the group (
). Accuracy improved dramatically when I changed to an LMT lower with a 2 stage trigger, lol. WOA makes a damn fine barrel, and I know I'm to blame for any bad groups with mine.
