The 16-inch barrel is 4150 CMV steel, chrome-lined, M4 profile with M203 cut, and magnetic-particle inspected. It uses a 1:7 RH twist for 5.56 NATO. An A2 birdcage flash suppressor with crush washer is installed on the threaded muzzle. The carbine-length gas system and direct impingement action keep the package true to the LE6920 pattern.

Factory markings include a barrel rollmark reading '13629 M P 5.56 NATO 1/7' and upper forging marks 'C' and square. The lower is marked 'M4 CARBINE CAL. 5.56MM' with an LE-prefix. The rifle was made in the United States. A QD sling socket has been cleanly installed in the handguard for modern sling attachment.
