Had this rail for a few years now and just noticed the rail is off. Tried it on different uppers and with different barrels with the same issue in the same direction on each. It seems like the internal face of the rail doesn’t sit square against the face of the barrel nut. Can’t ever remember dropping the rifle that would have bent it. Shimming straightened it oiut, but still bugs me. Anyone else ever deal with this?? Douglas barrel Attached File Colt barrel Attached File Shims Attached File Installed with shims Attached File |

It's not uncommon. It's also the reason that you can still have issues with doing Mod 2 URX3/2 conversions on rifles. It was especially noticeable on SR-25s. |

Interesting. I couldn’t find any info on it searching around. Do you think it’s the barrel nut or rail internal face that isn’t square? |
