EVO II Stainless Steel Single Shot Action


SKU: N/A Category:


The Mack Brothers EVO II Stainless Steel Single Shot Action is only offered in a short action with the option of bolt face: standard, magnum, or .223.

The solid bottom action comes with a self-indexing 17-4 stainless steel recoil lug, tool-less fire control, complete bolt, and a two piece aluminum 0 MOA Picatinny rail. The enhanced recoil lug adds thread tenon length for more contact with the barrel, increasing rigidity and overall precision in the rifle system. Additional features include a streamlined external bolt stop rotated five degrees above the stock line eliminating the need to inlet the stock for clearance.

The one piece bolt body is CNC machined from a 2″ round heat treated 4340 blank in only one operation. Each bolt is nitrided for reduced friction and superior durability. The bolt handle is threaded 1/4-28 and is compatible with two other bolt handle options that are available separately. These bolt knobs are only compatible with the EVO Gen II bolts.  All parts proudly made in America.

Weight: 30.8 oz.
