Looking to get rid of one of my Mk18 uppers. Daniel Defense built upper receiver with BCG, CH, and rail covers.
- Has no more than 400 rounds through it, all M193 with no malfunctions.
- This was not a safe queen so it has a couple minor marks on the rail.
- This upper had a VERY tight fit on my lowers, because of this the rear take down pin hole is marked up a bit, but still has a nice and tight fit.
