This Magnum Research MLR .22WMR / 22 Winchester Magnum Rimfire (MLR22WM) rifle is equipped with the Magnum Lite® revolutionary patented graphite barrel, exclusive to Magnum Research, or a stainless steel barrel. The patented uni-directional graphite fibers in the MRI graphite barrel, are parallel to the bore axis; and 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.
Other features of the MRI Magnum Lite® 22 Win Mag Rimfire include a Hogue OverMolded stock and a full floating barrel with an 11 degree muzzle crown for maximum accuracy. Magnum Lite® receivers are CNC machined from a 6061-T6 aircraft aluminum forging and include an integral Weaver type rail for optics. The MLR22WM from Magnum Research has an approximate weight of 4.45 lbs, barrel length of 19 inches, and over all length of 35.5 inches.
The Magnum Lite® rifle utilizes the Ruger 10/22® trigger group and the Ruger 10/22M® nine-shot rotary magazines. MRI bolts are manufactured and machined from heat treated and through hardened 4140 steel with minimum headspace for better accuracy.
The patented graphite barrel is unique to MRI. It provides lighter weight, better heat dissipation than steel and is extremely stiff.
The Magnum Research MAGNUM LITE® receivers are CNC (Computer Numeric Control) 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.
In all, The Semi-Automatic MLR-22-WM Magnum Lite® 22 Winchester Mag Rimfire Rifles make an excellent home-defense firearm for the person searching for a lightweight rifle option. The MLR-22-WM has a unique gas-assisted blowback operation and block under the barrel that taps a small amount of gas through a orifice hole in the barrel, an evolution of the classic design. With 10/22 Rotary Magazines and Trigger Group from Ruger, this MRI MLR22WM .22WMR rifle is available in many configurations.
