About Product

The SX-1 MTR features a patent-pending barrel changing and caliber conversion system. Extremely simple, the change can be administered in the field within minutes. To make the SX-1 MTR even more relevant, its modular design can easily be configured to use various magazines. Chambered in .308Win, the SX-1 MTR will accept SR-25 or AR-10 magazines. Or, by simply changing the mag well adapter, 10 round AI magazines. The same flexibility extends into larger calibers. Barrels in all 3 calibers are available in fluted or bull-barrel configuration. The magazine adapter has been designed specifically to be easily changed to fit different single or double stack magazines. It can also be custom made for most available magazines. MIL-STD 1913 Picatinny Rail mount is based directly on the barrel. This design allows operators to change barrels with preset scopes. Different adjustable triggers are available depending on the customer’s preferences. The SX-1 MTR is compatible with triggers according to Remington® 700 standard. The height and angle of the cheek piece, length of pull, and recoil pad of the stock are adjustable. The barrel rifling is processed in a CNC-controlled electrochemical machine. This avoids the transmission of thermal effects and mechanical stress to the material. Furthermore, this process allows us to produce barrels with unique uniformity and within tolerance zones that were not possible in a serial production before. Barrel change or caliber conversion can be performed by the operator in field conditions within minutes. The receiver is machined from an aluminum billet, designed to provide exact positioning and an increased contact area with the barrel. To achieve outstanding accuracy, the bolt locks inside the monolithic barrel. Special treatment of the steel parts increases surface hardness and enhances core strength. Steel parts ensure improved wear and corrosion resistance. High efficiency R&S muzzle brake fitted to M18x1 muzzle thread. Other muzzle threads available upon request. The buttstock can be mounted so it folds to either the left or right side. The thread in the receiver is compatible with AR-15 type buttstocks. Handguard: Octagonal cross section with the option to mount accessory rails via M5-Screws and/or M-LOK™. The rifle is delivered with a top mounted full length MIL-STD 1913 Picatinny Rail. Safety: FIRING position: The rifle is ready to fire. SAFE position: The firing pin is cocked, the sear is disengaged. The bolt can be operated. LOCKED position: The firing pin is cocked, the sear is disengaged. The bolt can not be operated. Ritter & Stark is situated in the Ferlach region of Carinthia, the very center of firearm manufacturing and production in Austria.
