FS woes: Just received a brand new 18.5" barrel ffor the 590A1. I had it sent directly from Mossberg to Vang Comp. VC gave it their treatment and sent it to me. Got it on the gun and the front sight seems noticeably canted to the left. Any prior experiences with the issue? Does VC index their ports off of the FS? They seem symmetrical to the FsBase. So I'm concerned if I have to have the FSBase moved its going to throw off the port work. It's too early here (East Coast) to reach VC or Mossy so I'm hoping to get some help here first but I'll post up news here as soon as I get it.
