An Austrian firm has just debuted a new big-bore, bolt action rifle that could become a player in a new program to outfit U.S. special operations troops with an updated long-range sniper rifle.
A new company in the market, Ritter Stark is making precision modular rifles from the ground up, using an innovative rifling technology and a barrel attachment system that virtually guarantees zero with optics matched to the caliber. Its SX-1 MTR chambered in .338 Lapua Magnum answers Special Operations Command's original call to provide commandos with a new "Advanced Sniper Rifle" that could be quickly reconfigured to several calibers and be deadly accurate each time.

What sets Ritter Stark apart from the competition is the novel way in which its SX-1 changes caliber. Most manufacturers have an interchangeable barrel that slides into the receiver and is attached to the action with a barrel nut or similar method. Ritter Stark built theirs with the barrel attached to the Picatinny-railed upper receiver and it's secured to the lower through simple hex bolts on the handguard.
"The caliber change takes a maximum of three minutes and you don't have to take it to a gunsmith to do it, you can just use a hex wrench," said Ritter Stark Deputy Managing Director Ekaterina Trakham during the 2016 Association of the U.S. Army conference in Washington, D.C.
The SX-1 can be switched to a .300 WinMag chambering, a .308 chambering and the .338 Lapua Magnum option. Reports indicate, however, that SOCOM has modified its ASR requirement for a .300 Norma Magnum chambering.
Like other high-end military sniper rifles, the SX-1's bolt locks inside the barrel for increased accuracy. And the company uses a proprietary "electrochemical" process to rifle its barrels, with company officials saying a .338 barrel is good for 5,000 rounds and a .308 can take 10,000 rounds before needing a replacement.
The SX-1 also has a three-position safety that's optimized for military and police applications, with two standard "fire" and "safe" positions, and a third one that not only blocks the firing pin but locks the bold handle down.
"We have a lot of experience working with security detail snipers who patrol the perimeter, and they're usually asked to engage the safety when they're on target," said Ritter Stark sales director Alexandr Chikin.
The SX-1 trigger also has a flip safety located under the trigger guard to limit movement that could give away a sniper's position and also blocks it when the rifle needs to be safed.
Company officials say the rifle should be commercially available within the next few months and cost around $6,000 for the .338 variant and $5,000 for the .308 one.
