I ordered a SWFA / Seekins compensator.  I received it the other day and it is obviously used, complete with wrench marks and carbon build up. No factory packaging either.  I contacted SWFA and was informed that all the SWFA comps were take-offs from complete uppers that were test fired.  Not a huge deal, but kind of disappointing because I thought I was getting a new part.  No where in the description does it say these are used.  They offered to exchange it for another used one, but that seems kind of pointless.  *Update - SWFA made it right and all is good.  Thanks

Heard back from SWFA, sounds like they are going to take care of me.  *Update, issue has been resolved.  Thanks SWFA!
