Pre used???? - CMMG Mk3 EML 11 Handguard Kit

My first thought was wow, nice packaging, however, upon removing this hand guard from fancy plastic tube package, the finish is noticeably worn on many spots possibly from shaking around inside the tube. When disassembling prior to install, the screws had been tightened so tight, the barrel nut would not release from inside the hand guard because it had been tightened so much that the knurled barrel nut had bitten into the clamped portion and the clamped portion would not release. I question if this part has been used before or if it was tightened this much when packaged? I’ve got pictures of I can figure out how to upload them.
