I recently had a package from Arisaka Defense get lost by USPS. Arisaka replaced it and about a week later the original package was delivered. I wrote RTS “return to sender” all over the original package and wife dropped it off at P.O. just for it be redelivered to me. I reached out to Arisaka and explained what happened so they emailed me a new shipping label. I then dropped off the package with the new label on 3/15 and it’s not even showing received yet. While all this took place, USPS lost an upper from BCM for 3 days. I’m very disappointed with them but some retailers only offer USPS.
