Overview

The FN 15 Military Collector M4 is FN America's semi-automatic collector-oriented M4-pattern rifle. The official addendum anchors it to a 14.7-inch barrel pinned and welded to 16.0 inches overall with an A2-style compensator, carbine-length direct gas system, 1:7 twist, 4140 alloy steel button-rifled chrome-plated barrel, RAS handguard with covers, UID-labeled receiver, ambidextrous selector, and A2-style sights. It is the right row for buyers who specifically want the FN Military Collector configuration, but the pinned-and-welded compensator and quad rail make it less flexible than modern free-float M-LOK duty rifles.
