Ammunition Tips »

USA based, Magnum Research, Inc. (MRI) has once again expanded their Magnum Lite® rimfire rifle product line with the introduction of the MLR Ultra 22LR with a high-tech modular tensioned-type barrel.

The modular barrel means that it has been constructed utilizing a superior quality of steel for the barrel which is attached to stainless steel breech and muzzle caps inside a thin-walled aluminum construction. The Ultra barrel took over a year to develop internally at Magnum Research and was extensively tested utilizing a variety of ammunition. When tested for accuracy against similarly constructed barrels, the Ultra barrel outshoots them significantly. Part of the reason for this is the patented heat sink located strategically inside the Ultra barrel itself.

The MLR22ATU measures 36-1/8” in length and weighs just 4 lbs. 8 oz. Barrel length is 18”. Features include 1 in 16 twist, Bentz chamber, ambidextrous thumbhole stock design with a comb designed for scope use, integral Weaver type scope mount base on the receiver, extended magazine release, swivel studs and checkering on the palm swell grip. The length of pull is 13-5/8”. The barrel is black anodized aluminum and has stainless steel breech and muzzle caps. The rifle utilizes the 10/22® trigger group and 10/22® rotary magazines.

10/22® is a registered trademark of Sturm, Ruger® & Co. Inc.
