Magnum Research, Inc. ® Introduces New .22LR Semi-Automatic Rifle

Pearl River, NY – USA based, Magnum Research, Inc. (MRI) introduces the latest in their Magnum Lite® line of .22 LR semi-automatic rifles. The exciting new features of the MLR22AT will quickly become a favorite among .22 fans.

Features of the new MLR22AT include an ambidextrous lightweight thumbhole 10/22® stock made from polypropylene with fiber additives for maximum strength. The new 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 new 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.

Additional features of the MLR22AT include: .22LR Benz target chamber designed specifically for semi-automatics; full floating barrel for maximum accuracy, CNC-machined receiver from 6061-T6 aircraft aluminum forging with an integral weaver-type rail for optics, and a black anodized finish. The MLR22AT weighs only 4.25 lbs., has a barrel length of 17 inches, and an overall length of 35.5 inches.

This rifle utilizes the 10/22® trigger group and 10/22® rotary magazines. MRI bolts are manufactured and machined from heat-treated and thoroughly hardened 4140 steel with minimum headspace for better accuracy.
