Ritter & Stark SX-1 MTR Modular Tactical Rifle

If you’re unfamiliar with Ritter & Stark, get ready to start hearing more about the company, thanks to its new SX-1 MTR.

The Austrian-based company will be exhibiting its initial product launch of the SX-1 Modular Tactical Rifle (MTR) at the AUSA Annual Meeting and Exposition, held in Washington D.C., Oct. 3-5, 2016.

The SX-1 MTR can be quickly and easily interchanged between a .308 Win., .300 Win Magnum and a .338 Lapua Magnum. It also allows operators to incorporate aftermarket magazines and drop-in upgrades with AR15/M16/M4 pistol grips and buttstocks that will fit the original Ritter & Stark folding buttstock mechanism.

Multiple features on the SX-1 MTR make this the ultimate precision rifle for serious shooters. The MIL-STD 1913 Picatinny rail is installed directly on the barrel, allowing barrel interchangeability with pre-set scopes for no shift of impact when changing calibers.

Easily and quickly done in the field, the patented caliber conversion system allows the barrel to be precisely positioned in the machined aluminum receiver with a greater area of contact allowing for more stability. The bolt is locked directly into the barrel breech giving the SX-1 unprecedented accuracy, shot after shot.

The SX-1 MTR barrel is processed in a unique CNC-controlled electrochemical machine. The process greatly limits any mechanical stress or the transmission of thermal effects on the barrel while ensuring a uniform match-grade barrel in either fluted or bull-barrel configuration.

Unlike other precision rifles, no matter the caliber, Ritter & Stark barrels are guaranteed to at least 5,000 rounds for .308Win and .338LM, and 2,000 rounds for .300WM before noticing any degradation in accuracy. For the shooter, this means that every rifle the company manufactures can achieve 0.5 MOA 3-­‐round groups or better with factory match grade ammunition.

Customization is key for military, law enforcement and precision long-range shooters as environments constantly change. The SX-1 MTR’s adaptability to fit the operator, as well as the scenario, is demonstrated in its adjustable cheekpiece, recoil pad, left/right folding capability of the buttstock and its acceptance of different aftermarket magazines, triggers and pistol grips.

The SX-1 MTR is also compatible with other manufacturers’ AR-10 magazines in the standard configuration.
