The Mauser Rimfire M-15 CA-compliant .22 LR rifle (Mauser Rimfire part no. 415.00.27) is a semi-auto rimfire built to meet California’s compliance requirements while still delivering a modern, feature-rich shooting experience. Made by Mauser Rimfire, it wears a black, side-folding stock with an adjustable cheekrest for a custom fit behind the optic of your choice, and a side-charging handle keeps the top of the receiver clear for mounting a red dot or scope. Flip-up front and rear sights ship standard as a backup, and a 10+1 round detachable magazine keeps you in the fight between reloads. Its right-hand, full-size configuration is built for shooters in restrictive states who still want a capable, modern .22 LR platform.
