Early this month, a relatively new firearms manufacturer from Austria has introduced a rifle in the United States that was designed with modularity as its main consideration. The Ritter & Stark SX-1 MTR Modular Tactical Rifle can be converted from one caliber to another to meet mission requirements.

The company says that SX-1 MTR can be quickly and easily interchanged between a .308 Win, .300 Win Magnum and .338 Lapua Magnum and furthermore, the ability to incorporate aftermarket magazines and drop-in upgrades with AR15/M16/M4 pistol grips and buttstocks. Indeed, it looks like a versatile rifle with such options afforded to the shooter.

Ritter & Stark claims that it is the most advanced and accurate tactical rifle in the world. Apart from that, it is reliable and comfortable allowing the shooter to focus on each shot with every rifle proof-shot tested for safety and accuracy in their state-of-the-art shooting range in their factory. To achieve this, the SX-1 uses a bolt that locked directly into the monolithic barrel breech for better shots on target with accuracy said to be up to 5,000 rounds for the .308 Win and .338LM, and 2,000 rounds for .300WM which translates into.05 MOA with three round groups using factory match grade ammo.  The rifling is processed using CNC to avoid transmission of thermal effects and mechanical stress to the material used in the producing the barrel.

The patented barrel conversion system allows the shooter to change the barrel for another caliber witin minutes in field conditions. The receiver was produced from an aluminum billet that was machined designed to give exact positioning for the barrel to fit quickly.

Pricing in the U.S. for the SX-1 is initially set at US$5,555.00 for the .308 and US$6,555.00 for the .300 and .388 with no information on actual release date. For airsoft companies looking for a new rifle design to make for the airsoft market, the SX-1 MTR should be a good candidate especially the ability to swap aftermarket parts is very much appealing to airsoft players, so they better work on getting a licensing agreement from Ritter & Stark soon.
