The FN15 DMR3 in 5.56 NATO (brand part no. 36-100683) is built for enhanced accuracy and faster shot-to-shot recovery, combining an 18-inch hybrid-profile barrel with a rifle-length gas system and a Geissele two-stage G2S trigger. FN America hammer-forges the chrome-lined barrel with a 1:8-inch twist from FN’s proprietary machine gun barrel steel, and a SureFire ProComp muzzle brake reduces both recoil impulse and muzzle rise. The rifle feeds from a 30-round FN polymer magazine and carries a fully free-floated Hodge Defense wedge-lock handguard over a low-profile, pinned gas block. An ambidextrous Radian Raptor-LT charging handle and safety selector round out the controls, finished in gray. Among modern sporting rifles in the AR rifles category, the DMR3 favors precision shooters who want a designated-marksman-style AR-15 built by FN.
