Ritter & Stark SX-1 Modular Tactical Rifle

Ritter Rifle

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.

    Been following this one for a while. Looks interesting. MSRP looks like it will match many of it’s peers.

    • Reef Blastbody

      ~1200-1500? or $3K +?

      • Gary Kirk

        It’d better be the former..

        • DW

          We wish XD

      • Richard

        $5,500 US for the .308, $6,500 US for the .338.

        Suddenly less excited about this rifle.

        • QuadGMoto

          Ugh. That makes the proven and more flexible Desert Tech SRS cheap by comparison.

        • JumpIf NotZero

          LOL that anyone thought a gun that comes with barrels that integrate the pic rail and action lugs would be $1500.

      • Rob

        By peers I referred to Modular bolt action rifles marketed toward military customers. So meaning the AI AW, Remington MSR, Sako M11, etc. Not the ruger RPR. So the 5-6k mark.

        • FarmerB

          AI AXMC ($8K+), Sako M10 ($10K), FN Ballista ($7.5K), Barrett MRAD ($5-6K)

  • Anomanom

    It is made of knight and strong.

  • Henry Reed

    Magazine compatibility is cool. Scope on the barrel is cool. Bolt layout is cool.


  • Gary Kirk

    Hey, another chassis system bolt gun.. For the buy you’re way to a sniper crowd.. Who needs to learn the basics, just buy one of these things, and you’re good

    • Martin M

      Just add Trackingpoint, and you’re good.

    • Reef Blastbody

      Heavens to Betsy! Perish the thought that companies should innovate and take advantage of improvements in metallurgy, materials science and other fields to build a better, easier to use rifle!

      No, no! We should all be relegated back to the black powder days and rolling block 45-70 Sharps with ladder sights, to winnow out the weak.

      • Gary Kirk

        Hey, I would’ve started with a 45-70 with buckhorn sights.. Then moved to ladder sights, possibly up to 45-90 or 45-110.. Or an ocular sight of brass construction, in one order or another. And then by God broke the smokeless barrier.. And maybe gitme one them newfangled 30-30s.. Think you missed my point there sparky.

        • Cope

          Do please share your point

  • LazyReader

    Another fine Death product by “Stark” Industries

  • Gary Kirk

    Ok, finally got to watch the video.. This is about as modular as swapping out the 3.9 in my Dakota for a 5.9.. Anyone mechanically inclined can do it.. Just might take some time..

  • Richard

    Austrians know how to make a promotional gun video!

  • Ευστάθιος Παλαιολόγος

    I’ve been reading that the company gives a barrel life of 5000 rounds for 308 and 338 but only 2000 rounds for 300WM
    Why such a large difference for the 300WM?

  • EzGoingKev

    MSR is still king IMO.
