Radical Firearms' RF-15 in Flat Dark Earth Cerakote is a cosmetically differentiated version of the standard RF-15 carbine. The in-house chrome-moly 16-inch barrel, M-LOK handguard, and mil-spec lower are unchanged. The FDE finish is the most popular color variant in Radical's lineup and demonstrates demand for non-black AR finishes at the value price tier.
