Starting from the front, the D-M4LE comes with a standard A2 flash suppressor, also called a compensator if you have been through certain schools. This A2FS was properly timed with the use of a crush washer. Pretty standard stuff, and assembly was up to spec as far as I am concerned. While I don't need a weapon to look pretty, details like no wrench markings on the A2 FS show attention is going into the little things.

The barrel is stamped "5.56 NATO 1x7 CHROMED" indicating that the weapon is chambered in 5.56 Nato, 1/7 twist, and chromed lined. For those who wonder about barrel steel makeup, it is 4150.
