Nosler M21 Model 21 Bolt-Action Rifle - 27 Nosler, 24" Barrel, Synthetic Stock, Matte Black Finish

The Nosler M21 bolt-action rifle in 27 Nosler represents a modern approach to precision hunting—built by shooters who understand what works in the field and at the range. This isn't a rifle trying to be something it isn't; it's a production firearm engineered with the performance and attention to detail you'd expect from a custom build, but available off the shelf. The 24-inch barrel and 7.1-pound weight strike a practical balance between velocity and packability, making it equally at home on a long-range day at the range or packed into remote country where every ounce matters.

What sets the M21 apart is the collaboration between Nosler and Mack Brothers, the South Dakota action builders known for their precision rifle work. The result is a receiver and action that pulls together the proven features of their EVO platform with Nosler's own refinements—a foundation that works right out of the box without excuses. The wire EDM machining and nitride coating aren't marketing fluff; they're practical choices that deliver consistent, reliable function across seasons and conditions. Pair that with a TriggerTech trigger, Shilen match-grade stainless barrel, and McMillan carbon fiber stock, and you're looking at component quality that typically appears only on semi-custom builds.

The 27 Nosler cartridge deserves a rifle worthy of it. This is a Nosler-designed round built for velocity and energy retention at distance, and the M21's 1:8.5 twist and #3 barrel contour are optimized to handle it. Whether you're chasing elk at elevation, testing your long-range skills, or building a reliable hunting rifle that won't let you down, the M21 delivers precision and packable reliability without compromise.
