Last year, Ritter & Stark (R&S) premiered their SX-1 at Enforce Tac. Since then they used the time to lay hands on all details to make it even better. Now the SX-1 Modular Tactical Rifle (MTR) is ready for series production. According to R&S, the SX-1 MTR is the result of thousands of hours of R&D, material testing & selection, and engineering prowess overseen by gunsmiths and dedicated professionals from around the world. The SX-1 MTR gives the shooter options and versatility in the field unmatched to any other products.
The SX-1 MTR features a patent-pending barrel changing and calibre conversion system. Extremely simple, the change can be administered in the field within minutes. For that, last year you had to work on six screws from both sides, now there are only three screws from one side. It is so fast and simple to change the barrel. 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 calibres.
In addition, the SX-1 MTR accuracy level achievements are a result of our patented rifling process. Through extensive research and testing they have patented the ECM (Electrochemical Machining) barrel rifling process.
No matter the calibre, the barrels are guaranteed to last at least 5,000 rounds for .308Win and .338LM, and 2,000 rounds for .300WM before noticing any degradation in accuracy.
