Keystone 722 Carbon Precision Trainer Features The Keystone 722 Carbon Precision Trainer is built around a bolt-action rimfire receiver chambered in .22 LR pairing a lightweight carbon fiber barrel with a 1-in-16 twist rate to stabilize standard velocity rimfire loads for reliable range accuracy. The threaded 1/2x28 muzzle accepts a suppressor or muzzle device extending the trainer s usefulness into suppressed instruction and low-noise practice sessions. A two-position safety lever gives new shooters a simple intuitive control to learn proper firearm handling and range safety procedures from the very first range session. Feeding from a 7-round magazine the action cycles smoothly and reinforces basic bolt manipulation drills that translate directly to larger centerfire platforms. The aluminum Urban Sniper collapsible stock is the centerpiece of the ergonomic package adjusting the rifle s overall length from 30.75 to 34 inches to fit shooters ranging from young students to full grown adults. This folding stock design also collapses the rifle down for compact transport and storage making it a practical choice for instructors moving between range stations or students storing a rifle at home. At roughly 6 lbs unloaded the rifle stays light enough for extended range sessions without fatiguing new shooters during repetitive drills. Finished in a durable blued metal treatment the 722 Carbon Precision Trainer is available for sale at GrabAGun as a purpose-built introductory rimfire rifle for shooting schools youth programs and first-time rifle owners.
