The Magnum Lite from Magnum Research is an exciting rifle platform for fans of the expensive .22 LR catridge. The 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 stock design also features a checkered semi-palmswell 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 6 times 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, resulting in rimfire performance of extreme accuracy. Magnum Light receivers are CNC machined from a 6061-T6 aircraft aluminum forging and include an integral Weaver type rail for optics. The bolts are manufactured and machined from heat treated 4140 steel with tight bolt face depth tolerances for better accuracy. The rifle also utilizes the 10/22 trigger group and 10/22 rotary magazines.
