| I recently bought an upper with a barrel that looks to be marked CH SWI from what I can tell. It's chrome lined, but I'm trying to determine the MFG. The FSB is canted, but I'm thinking it's not torqued correctly and haven't had time to take it apart. Can anyone tell me anything about these barrels? |
