BRN22 Build
Building a Custom Ruger 10/22 Clone With the Brownells BRN-22 Receiver
In this Brownells Tech Tip, Caleb walks through a complete Ruger 10/22 style rifle build using the Brownells BRN-22 receiver. Designed to accept Ruger factory components and most aftermarket 10/22 parts, the BRN-22 gives shooters an affordable and versatile foundation for building a custom rimfire rifle.
Whether the goal is a lightweight field rifle, a suppressor-ready plinker, or a match-grade precision setup, the BRN-22 receiver offers compatibility and performance without requiring major custom fitting.
Starting the Build With the BRN-22 Receiver
The build begins with a clear anodized BRN-22 receiver secured in a Brownells gunsmithing vise using protective vise pads. Caleb explains that the receiver is available in both integral rail and removable rail versions, giving shooters flexibility depending on their optic setup.
Although this receiver has already seen heavy use at trade shows, it still demonstrates the durability and machining quality expected from a dedicated 10/22 platform receiver.
Installing the Lightweight Beyer Barrel
For the barrel, this build uses a lightweight Beyer bull barrel. Even though the profile resembles a traditional heavy bull barrel, the aluminum outer construction with a steel liner keeps overall weight down while maintaining accuracy.
Before installation, a light coat of Brownells Action Lube Plus is applied to the barrel tenon. The barrel is then aligned carefully with the receiver before the V-block is installed underneath.
Caleb explains the importance of proper barrel alignment and demonstrates how the V-block system secures the barrel inside the receiver. After verifying alignment, the V-block screws are torqued to 20 inch-pounds.
Installing the Bolt and Charging Handle
Next comes installation of the Brownells match-grade bolt and Power Custom charging handle. A lightweight oil is used for lubrication, which works especially well for rimfire rifles due to the lighter operating system.
The charging handle is inserted through the ejection port before the bolt is carefully worked into place under spring tension. Once installed, the bolt buffer is added to prevent the bolt from cycling rearward far enough to exit the receiver.
Instead of using the standard steel Ruger buffer, this build uses a softer aftermarket buffer to reduce operating noise and improve suppressed shooting performance.
Adding the Trigger Group
For the trigger assembly, Caleb installs a Volquartsen trigger group equipped with an extended magazine release paddle. While more expensive than factory options, the Volquartsen unit provides improved trigger performance and excellent ergonomics for competition or precision shooting.
The trigger group installs easily using standard Ruger receiver pins, and a small amount of lubricant is applied to the hammer engagement surfaces during assembly.
Installing the Victor Company Stock
The rifle is then fitted into a Victor Company stock, one of Caleb’s preferred non-chassis 10/22 stock options. The stock includes multiple sling mounting options, integrated QD sockets, aluminum bedding surfaces, and an ergonomic grip design suitable for both left- and right-handed shooters.
A key part of the installation process involves adjusting the rear tension screw. This brass-tipped set screw removes movement between the receiver and stock, improving overall lockup and consistency.
After adjustment, the action screw is torqued to approximately 20 to 25 inch-pounds.
Suppressor and Optic Installation
To complete the build, Caleb installs a Dead Air RXD22 Ti suppressor setup using the Zeno Mini mount system. The suppressor mount threads directly onto the barrel and is tightened using standard armorer’s tools.
For optics, the rifle receives a Sig Romeo5 red dot sight. Caleb demonstrates proper optic mounting technique by pushing the optic forward in the rail slot before torqueing the mount screws.
The final assembly step includes reinstalling the extended magazine release paddles and checking trigger feel and adjustment.
A Fully Customizable Rimfire Platform
By the end of the build, the BRN-22 receiver has been transformed into a fully customized Ruger 10/22 style rifle capable of serving as a suppressor host, competition rimfire gun, or general-purpose plinker.
The project highlights just how modular the 10/22 platform has become, especially when combined with quality aftermarket components and careful assembly practices.
For shooters looking to build a reliable and accurate rimfire rifle, the BRN-22 platform offers an excellent starting point with nearly endless customization possibilities.
