Brownells BRN-22R Magpul Hunter X-22 Chassis .22 LR Semi-Auto Rifle
Purpose-built for accuracy, modularity, and pure rimfire fun, this custom-assembled BRN-22R marries Brownells’ precision-machined billet receiver with Ruger-pattern internals and Magpul’s fully featured Hunter X-22 chassis. A factory-threaded 18.5" sporter barrel, integral 0-MOA Picatinny top rail, and lightweight 4.8–5.2 lb balance make it equally at home on the bench, in the field, or as the foundation for a personalized trainer build. Collectors will appreciate the later-production serial (BRN-22R-12274) and the rifle’s full compatibility with the expansive 10/22 aftermarket ecosystem, while shooters will enjoy reliable 10-round rotary magazines, AR-like ergonomics, and a crisp BX-style trigger.
Condition
Good overall condition with honest evidence of prior use. The matte finishes on receiver and barrel show light, superficial scratches and small handling marks but no deep gouges or corrosion. Stock and forend display minor scuffs consistent with careful range time. Bore is clean and shiny; lands and grooves remain well-defined with only minor wear. Mechanicals cycle smoothly, safety and magazine catch engage positively, and the threaded muzzle is unobstructed and supplied with its factory thread protector.
