Good rail, terrible barrel nut - Seekins Precision MCSRV2 M-Lok Rail System

Good light strong rail, has anti rotation tabs, anti rotation qd mounts, and strong mounting to barrel but. But the barrel nut is some terrible 2 piece design thing, you have to time it for the gas tube, have to time it perfectly for the rail retention screws which requires the bigger but to be loose and not even close to the upper, then there's no way to torque the smaller barrel but cause it's a 3/4 inch hex but, had to use a crescent wrench and hoped it's tight enough. Beware.
