The APF DMR 2.0 (brand part no. RI246SG) is an American-made AR-15 designated marksman rifle built by APF Armory in Alexandria, Minnesota, chambered here in .204 Ruger and finished in Stealth Gray Cerakote. It delivers pinpoint precision from an 18-inch stainless barrel, matched with a rifle-length gas system for smooth cycling and a lightweight profile suited to hunters, competitors, and tactical shooters alike. The DMR 2.0 splits the difference between a compact carbine and a full-length precision rifle. Every detail is built for repeatable accuracy shot after shot.
