Great (with some caveats)
The rail and barrel nut are both excellent. Lockup and rigidity are both awesome and there's no wiggle side to side (as often experienced with slip/friction-fit rails that are popular today). There are a few issues that Ergo could easily address to improve the installation experience: 1. The included hex screws for securing the rail to the barrel nut strip under any meaningful amount of torque. A torque specification is not provided, but even at a conservative 15 in-lb, three out of the eight screws stripped out with a brand new hex bit. Save yourself the headache and plan to buy some 8-32 x 5/8" countersunk torx screws. They are not expensive and significantly improve the installation experience. 2. All of the included barrel shims for timing the nut are the same thickness. I could properly time the nut with any combination of provided shims and typical barrel nut torque. Along with the new screws, plan to buy a variety pack of shims (or at least a pack of 0.001" shims). 3. Actual length of the rail is a little longer than advertised (about 0.2" with the 12" model). Add the additional gap between the upper from having to time the barrel nut and secure the rail to it, now it's (practically speaking) even longer. Very important if you're planning on running a suppressor. I'm happy with it, but it took some work to get to that point. Since this is not a very popular model, I could not find many reviews online. Hopefully this is helpful to someone else.
