Mack Brothers Actions: American-Made Precision You Can Rely On

Not every outstanding precision action gets the marketing budget it deserves. Mack Brothers is one of those companies — known primarily among serious custom rifle builders and PRS competitors, less so to the casual shooter. At Ares Custom Rifles, that's exactly the kind of company we like to work with: the ones focused on the product, not the hype.

Craftsmanship First

Mack Brothers actions are made in the United States and machined to the tolerances you'd expect from a custom action at this price tier. Bolt-to-receiver fit is exceptionally smooth — you'll notice it the first time you run the bolt. Bolt lugs are lapped and the bolt face is trued, which means the barrel work we do downstream starts from a solid reference point.

Versatile Platform

One of the things we appreciate about Mack Brothers is the versatility of their action family. They offer multiple action lengths and bolt face options, which gives us flexibility when building for less-common cartridges. If a customer comes in wanting a custom 7mm or a big magnum that doesn't fit neatly into a Remington 700 footprint, Mack Brothers has options worth considering.

Who Should Consider a Mack Brothers Build

Customers who want American-made quality, a smooth-running action, and aren't interested in paying for brand name recognition will be very happy with a Mack Brothers build. These actions are for serious shooters who've done their research.
