Magnum Research Releases MLR Ultra .22LR Rifle

Adding to the Magnum Lite line, Magnum Research has released the MLR Ultra .22LR.  It features a modular tension-type barrel made from very high quality steel. One variant of the rifle is also threaded for muzzle devices or a suppressor. Having shot some of their rimfire rifles, they are very well made and quite accurate.  So I have no doubt that Magnum Research will continue with that quality with this new rifle.

The rifle is actually based off the 10/22, using the trigger group and magazines.  Magnum Research is also offering barrels that you can add to your own 10/22.  Check out their press release below for more info!



Pomona, NY – 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. MSRP on the MLR22ATU is $544.00.

A similar model to the MLR22ATU is the MLRATUT. The difference between the two rifles is that the MLR22ATUT can accommodate a suppressor and has muzzle threads of ½ x 28. It is supplied with a thread protector. The weight is the same, but the overall length is 36-5/8” and barrel length is 18-1/2”. Both rifles utilize the 10/22® trigger group and 10/22® rotary magazines. MSRP on the MLR22ATUT is $571.00. Both barrels are also sold separately for upgrading 10/22 rifles.

    What did they chamber it in? Why would they choose such a rare old round? To hear the old-timers tell it, you could get as much as 500 of them at a time! RIDICULOUS!

    • dan

      Stop spreading tall tales, everyone knows that the .22lr cartridge never really existed, companies that chamber rifles in that caliber are akin to companies that sell special equipment to find ghosts and talk to aliens. To keep the myth alive.

        It exists! I have seen it. You have to travel across the sea (AKA the big lake with no end in sight). There you probably have to kill a flying whale or something as a sacrifice…but I don’t know about that part, I started out on the other side of the ocean.

        • Zachary marrs

          You forgot the part where you have to build a row boat out of unobtanium

      • El Duderino

        You forget what the “LR” part stands for. “Ludicrously Rare.”

    • Guest

      Indeed, archaeological evidence suggests it was once the most prolific species of ammunition.

      • Zachary marrs

        Cheaper than dirt?

  • Zachary marrs

    Thought I’d just do this

    • kipy

      Dinkleburg has had all the 22lr this whole time?!

      • ATman


        I live in the peoples republic of Canada and I feel like going out of my way to purchase a few hundred rounds of ammo just to for the heck of it. No shortage here.

  • ole timer

    Not only were 22lr plentiful, they could be had for 50cents a box.
    And heaven forbid, even cheaper on sale. I know, I was there, sooooo long ago.

    • Jack Morris

      Lies! This could not have happened.
      I’ve only ever seen pictures of this rare specimen.

      • dan

        I don’t even know what to believe anymore. Have I been living a lie this whole time?

        • Jack Morris

          This is the only logical explanation seeing as how 22lr does not exist.

  • NZLongRange

    It would be mean to mention that little old New Zealand has an abundance of the stuff…. purchased 4 bricks just yesterday. We have even had people emailing the store from the US trying to get it air freighted back. is it still that bad?

    • Ben M

      Yes. It has been a year and a half since I have seen a bulk pack on the shelves. Anywhere.

      • Wetcoaster

        Lots of the stuff in Canada as well, and that includes from US companies.

        I expect that sooner or later, the market is going to glut, especially once the withdrawal from A-stan is complete and all those 5.56 and 7.62 lines start making commercial calibres again.

        • Blake

          Those machines won’t be making rimfire cartridges any time soon…

  • wetcorps

    I love how 100% how the comments are about the ammo and not the carbine.
    But it’s a little unfair for this poor gun, so I will restore some balance.

    Yamn, another 10/22.

    • Blake

      At least its another *very accurate* 10/22.

  • The Brigadier

    The gap between the forward rest and the barrel is quite simply ugly. If this gun had to be taken into combat, it would catch every bush or branch and you would be weaponless. I understand they are trying to balance weight and functionality, but this odd looking little beast needs to go back to the drawing boards.

  • Unlicensed Dremel

    Too bad it’s not a straight-pull repeater like a PWS T3/Summit, and with a 9 twist barrel – then we’d be cookin with butane.
