The SX-1 Modular Tactical Rifle was designed to allow operators to customise the rifle to fit any specific mission requirements. The rifle can be supplied with three interchangeable calibers: .308 Win, .300 Win Magnum and .338 Lapua Magnum. With the SX-1 MTR operators can utilise different aftermarket magazines, AR-15 compatible pistol grips and buttstocks that fit to the original R&S buttstock folding mechanism.
Ritter & Stark team designed a very accurate rifle, comfortable and reliable to the extent that the operator can fully rely on the equipment and concentrate on the mission. Every rifle is proof shot tested for safety and accuracy at the factory.
