Seamlessly integrating with the Ruger® 10/22® and 10/22 Takedown® series of rifles, the MBS 22 from High Tower Armory is far from just another bullpup conversion. The MBS 22 retains all of the benefits bullpups are known for, like compactness and balance, while dramatically mitigating the drawbacks of other designs, such as poor trigger performance, cumbersome ergonomics, and complex disassembly steps. Moreover, it also combines the utility of many other accessories, like a left side charging handle, quick release bolt lock, and M-LOK® handguard, into one system.
By deviating from the typical left and right clamshell design, our Modular Bullpup System eliminates the nuts and bolts inherent to other conversions and allows the rifle to be field stripped in a matter of seconds. Removing three pins and the factory takedown screw is all it takes to separate the 10/22's receiver and trigger assembly from the MBS 22. Optics and accessories mounted to the MBS 22's picatinny rails and M-LOK slots can even be left in place to help maintain zero.
Another feature of the MBS 22 that sets it apart from the competition is the trigger linkage. Our dual arm linkage is made from nitride treated steel for maximum corrosion resistance and rigidity. Uniquely, it can be set up with either a "Direct" or "Cammed" trigger linkage system. The Cammed Trigger Linkage actually reduces the perceived weight of the factory trigger from about 5 pounds to around 3.5 pounds, with absolutely no modification to the OEM fire control components. The Direct Pull Linkage works like a more traditional bullpup linkage, transferring energy in a smooth, linear motion to ensure crisp breaks and quick resets. The trigger linkage can be adjusted for both take-up and overtravel and even the spring weight of the MBS 22's trigger linkage can be adjusted for unparalleled trigger customization among bullpup conversions.
In the MBS 22's lightest configuration (deflector, knuckle guard, and accessories removed), the complete rifle weighs only slightly more than a 10/22 in the typical OEM configuration, or 5.25 pounds. At only 26.25" long with an 18" barrel, the MBS 22 is as compact as an SBR without the tax stamp and better balanced than a traditional rifle, allowing for effortless one-handed shooting. Bull barrels up to .920" in diameter can be used, as well as a variety of other types, like the Ruger factory tapered barrel, thanks to three sizes of interchangeable bushings included with each kit. If set up as an SBR, barrels as short as 9" can be used and the open front handguard allows for suppressors to nest inside for an incredibly small and maneuverable overall package.
Featuring a removable shell deflector, ambidextrous charging handles, and a trigger block safety, the MBS 22 can be utilized by left or right-handed users out of the box. The charging handle even incorporates a rock-to-lock mechanism, allowing the bolt to be held open quickly from either side and then closed with a slap. Additionally, the MBS 22 conceals three storage compartments: two inside the stock and one in the grip, enclosed by the removable knuckle guard. These compartments can house tools, parts, batteries, and even a spare BX-1 rotary magazine, spring loaded for easy access. Made in the USA from durable glass reinforced injection molded polymer and nitride treated steel, the MBS 22 is built to be used for a lifetime, which is why we can confidently guarantee it with the same lifetime warranty that covers all HTA products. *Ruger 10/22 and any accessories shown not included.
