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 BDL action comes with a self-indexing 17-4 stainless recoil lug, complete bolt, and a two-piece 0 MOA Picatinny rail. Wyatt’s Extended Magazine Boxes are compatible with the action. The overall cartridge length for the short action is 2.990″.
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.
