Mack Bros EVO titanium action


Out of stock

Email when stock available


The Mack Brothers EVO titanium action is made from a 6Al-4V titanium alloy, reducing the weight of a standard Rem. 700 SA receiver by 35%. Each action is cut utilizing advanced wire EDM technology for precision tolerances and reduced internal residual stress on the action compared to traditional machining.

Each action comes with a self-indexing titanium recoil lug, complete bolt, and a 20 MOA Picatinny rail. The enhanced recoil lug adds thread length for more contact with the barrel and increased overall precision in your rifle. The 20 MOA Picatinny rail can easily be removed for the hole alignment to be compatible with a set of front Remington rings for complete customization. Other features include a streamlined external bolt stop located above the stock line and an integral trigger hanger system for ease of assembly and enhanced trigger repeat-ability in the field.
