The Mack Brothers EVO II Stainless Steel Short Action starts from a 416 heat treated billet, and is CNC machined in only two operations.
The DBM action comes with a self-indexing 17-4 stainless recoil lug, complete bolt, and 20 MOA Picatinny rail.
The one piece bolt body is also CNC machined from a 2″ round heat treated 4340 blank in only one operation and features a modified M16 style extractor. Each bolt is nitrided for reduced friction and superior durability.
