The APF MLR Compact .300 Win Mag rifle with a carbon fiber barrel (brand part no. MLRC300WMCF) is a semi-auto magnum built for hunters and long-range shooters who want reach without carrying a full-length rifle. APF builds the MLR Compact around an 18-inch Proof Research carbon fiber barrel and a precision-machined billet receiver set. A rifle-length gas system, an adjustable gas block and a drop-in single-stage trigger round out the design. Four 5-round magazines come with it.
