First Look: Rival Arms R-22 Precision Chassis System

posted on December 7, 2020

Rival Arms is a manufacturer of precision firearm components for do-it-yourself gun enthusiasts, and now the company is rolling out the R-22 Precision Chassis System for guns with Ruger 10/22-style barreled actions. With this new chassis, Rival Arms takes their knowledge and skill at making premium handgun components and expands into the world of performance rimfire upgrades, beginning with the R-22 chassis.

The Ruger 10/22 barreled action is a popular choice in the rimfire rifle community as a reliable, and easily upgradable gun. Rival Arms enhances this platform with the R-22 Precision Chassis System which is designed for use with 10/22-style barreled actions and features a 1-inch maximum barrel diameter. The R-22 chassis is CNC-machined from billet aluminum for precise consistency, strength, and rigidity. The chassis weighs only 1 pound, and because it uses aluminum, it maintains the lightweight design of the 10/22 platform. The chassis will be available in a hard black anodized finish as well as a KG GunKote Flat Dark Earth (FDE) and Satin Gray finishes.

The R-22 chassis includes scalloped texturing on the forend to enhance grip and eleven integrated M-Lok slots to mount accessories and  reduce weight. The R-22 chassis accepts most vertical or angled AR-style pistol grips and is threaded to accommodate 1 3/16-16 inch Mil-Spec buffer tubes for a wide variety of stock options. The forend is also tapped to accept a sling swivel stud, and the threads are also positioned for sling or bipod use.

Upgrading to the Rival Arms R-22 chassis system is a project any DIY firearms enthusiast can accomplish at home, and because the R-22 can use most of the many different AR-style grips and buttstocks on the market, it allows for numerous customization possibilities. 

MSRP for the R-22 chassis starts at $254.99. For more information on this product and other products from Rival Arms, please visit
