Features of the MLR22AT include an ambidextrous lightweight thumbhole 10/22® stock made from polypropylene with fiber additives for maximum strength. The stock design features a comb height designed for comfort, with a semi-palm swell on both sides of the pistol grip, a molded-to-fit rubber butt plate, and the comb height easily accommodates optics. The rifle will be 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 handle and dissipate heat up to 43% faster than steel. The result is extremely accurate rimfire performance.
