Ritter & Stark will introduce its SX-1 Modular Tactical Rifle (MTR) to the US market at the Association of the United States Army (AUSA) Annual Meeting and Exposition next month. TFB readers got a sneak peek of this gun in May when Steve published a number of guns that were on display at the Defense Services Asia Exhibition & Conference.

The SX-1 MTR is offered in three calibers (see the below chart for all specs) and any of the three can be converted to shoot either of the remaining two. The rifle is designed to work with a variety of off-the-shelf parts to help make it adaptable to your needs. Examples include the ability to use AR-15/M-4 style buttstocks and pistol grips, aftermarket triggers and other companies’ magazines.

In the below video, a company representative shows how to convert the rifle from one caliber to another. It’s not as easy as swapping an AR upper, but the average shooter should be able to handle it easily.

Many shooters in the United States are probably not familiar with the Ritter & Stark name. The company is relatively new, having formed in 2015. It is based in Austria, and is said to have attracted some very good engineering talent from the area. In addition to the SX-1 MTR, the company is developing additional products that are expected to be introduced in 2017.
