Very nice fit and finish. - Aero Precision M4E1 Threaded 16in .300 Blackout w/ ATLAS S-ONE Handguard Complete Upper Receiver with Flash Hider

The upper came well packaged in a cardboard box with foam egg crate packaging. The quality of the materials seems high the fit and finishes very nice and I’m extremely happy at the moment. The only difficulty I had was getting the charging handle to seat due to the Cerakote making the Tolerances a little snug. After seating the charging handle it functions as it should. I haven’t fired it yet so that’s why the four star rating but I’m expecting good results
