The MLR22AT will give .22LR rifle shooters something to get excited about. The new ambidextrous lightweight thumbhole 10/22 stock is made of polypropylene with fiber additives for maximum strength. The stock comb height is designed high enough to comfortably and properly shoot with optics. The new stock design also features a checkered semi palm swell on both sides of the pistol grip, and a molded-to-fit hard rubber butt plate attached with screws. This rifle is equipped with the Magnum Lite® revolutionary patented graphite bull barrel, exclusive to Magnum Research. The patented uni-directional graphite fibers, parallel to the bore axis, results in a barrel with 6x the stiffness of the equivalent weight of steel. The lighter barrel weights (from 13-16 oz, depending on barrel length) are easier to wield and dissipate heat up to 43% faster than steel. The result is rim fire performance of extreme accuracy. This rifle utilizes the 10/22 trigger group and 10/22 rotary magazines.
