Model 21 Rifles
A rifle for the next decade, the Model 21 is a feature-rich production firearm that has the feel and performance of a custom build. Featuring premium components throughout and weighing roughly 7 pounds depending on the cartridge, the Model 21 rifle brings exceptional precision and packable reliability to any hunt.
The heart of the rifle is Nosler’s new Model 21 action, designed in collaboration with Mack Brothers, the reputable South Dakota sibling duo with a growing reputation for building some of the finest rifle actions in the industry. Most notably, their popular EVO action has built an impressive following among serious precision shooters since its introduction in 2018. The newly designed Model 21 blends the best features of the EVO with unique Nosler-engineered customizations, delivering a solid foundation for peak performance right out of the box.



A Piece of the Action
Blueprinted from birth on advanced wire EDM equipment, the Model 21 action was thoughtfully designed to deliver exceptional performance in a user-friendly platform with several built-in custom features throughout. Among these features is a spiral fluted, one-piece, Nitride coated bolt made of 4340 Chrome Moly steel. In addition to a sleek aesthetic, and nearly effortless functioning, the fluted design provides a reduction in weight and helps to channel debris, preventing the bolt from jamming in environments where dirt and sand is an issue. In line with the Model 21 action’s practical design philosophy, the bolt’s upgraded M16-style extractor and fire control group feature tool-less takedown.
Upgraded Bolt
The bolt is precision-machined from a single billet of hardened 4340 Chrome Molybdenum steel for superior strength and durability. Fluted for reduced contact with the receiver, it ensures a smooth, seamless operation when opening and closing. To enhance its smoothness and longevity, the bolt is coated with NIB-X (Nitride). It features a modified M-16 style extractor, delivering exceptional extraction performance with a tool-free design for easy disassembly and cleaning. The bolt handle is threaded with a 5/16-24 TPI pattern, allowing compatibility with a wide range of popular bolt handle configurations.



Carbon Fiber Stock
When hunters think of a strong, dependable yet lightweight stock, the #1 material they think of is carbon fiber for accuracy, reliability and strength. The stock on the Model 21 is constructed of 100% carbon fiber to ensure dependability while maintaining the ultra-light feel so many hunters desire. Included for strength are aluminum pillars and a 1” recoil pad that is set at a standard 13.5” LOP. The stock is finished with an all-weather epoxy style paint to guard your rifle from all the elements you may encounter.



Additional Features



M21 Barrel Features
Each barrel is equipped with a precision-machined recessed crown and a threaded muzzle (available in 1/2-28 or 5/8-24 TPI). It includes a knurled thread protector that is easy to remove for added convenience.



M21 Recoil Lug Features
Self-indexing 17-4 SS recoil lug, which eliminates recoil lug alignment issues and increases thread shank length for added barrel support.



M21 Trigger Features
The Model 21 is equipped with an externally adjustable trigger, allowing users to fine-tune the pull weight between 2.5 and 5.5 pounds. Engineered for reliability in the harshest environments, it incorporates Frictionless Release Technology™ to ensure consistent performance even when other triggers may fail.
