Need improvement - Midwest Industries 15in Combat Rail T-Series One Piece Free Float Handguard

1. The packaging box say item is fully honed and de-burred , but it is not, some edges are burred, and a lot of burs in the interior circles. 2. The anti rotation tabs are tight on some upper receivers, and simply too small and will not fit on some other upper receivers( will not fit on the aero one I tried )
