Upper:

Machined from 7075 T6 forgings, this FREE upper receiver features a mil-std 1913 rail for mounting optics and accessories and has M4 feedramps.

These uppers are machined to extremely tight tolerances for a more accurate build. Seating the barrel may take additional force. Light taps with a rubber mallet will do the trick.
