Underground Tactical Barrels?

[baconmaker]

Hello all I'm new to the forum. I'm on my third ar build but first 6.5 build. I ordered a 20" medium contour 6.5 barrel cerekoted in FDE and the complete bcg with the .136 bolt face from Underground Tactical. They told me it would be about 3 months for my barrel for manufacturing. I have a couple guys I work with that have the 300 blackout and the have good results. I will hopefully have more info for you in a few weeks.
