High-Tech Tactical Rifle from Austria’s Ritter & Stark

There’s a new long-range precision tactical rifle from Ritter & Stark (R&S) of Austria. The new SX-1 Modular Tactical Rifle (MTR) is designed to allow rapid barrel changes for three chamberings: .308 Winchester, .300 Winchester Magnum, and .338 Lapua Magnum.

Notably, the scope rail is mounted on the barrel itself, and the bolt locks directly into the barrel. This patented system allows scope, rail, and barrel to be swapped out as one integrated assembly, which should definitely help maintain zero when barrels are exchanged.

Ritter & Stark explains: “The MIL-STD 1913 Picatinny rail is installed directly on the barrel, allowing barrel interchangeability with pre-set scopes for no shift of impact when changing calibers. Easily and quickly done in the field, the patented caliber conversion system allows the barrel to be precisely positioned in the machined aluminum receiver with a greater area of contact allowing for more stability. The bolt is locked directly into the barrel breech[.]”

CNC-Controlled Rifling Process
Ritter & Stark states: “The rifling is processed in a CNC-controlled electrochemical machine. This avoids the transmission of thermal effects and mechanical stress to the material. Furthermore, this process allows us to produce barrels with unique uniformity and within tolerance zones that were not possible in a serial production before.” This is very interesting technology, and we’d like to learn more about it.

Accuracy Guarantee and Barrel Life Guarantee
Apparently the CNC-controlled rifling process works well as Ritter & Stark guarantees that its barrels maintain accuracy for a long time. The Austrian company states: “Our barrels are guaranteed to at least 5,000 rounds for .308 Win and .338 LM, and 2,000 rounds for .300 WM before noticing any degradation in accuracy.” That kind of claim certainly invites a long-term test. Who’s got enough ammo? Ritter & Stark also claims that “every rifle we manufacture can achieve 0.5 MOA 3-­round groups or better with factory match-grade ammunition.”

The Ritter & Stark SX-1 MTR is designed for adaptability. It will accept third-party Rem 700-compatible triggers as well as a variety of AR-type grips. In addition, the SX-1, in standard configuration, will accept other manufacturers’ AI, SR25, or AR10 magazines. The rifle can also accept other buttstock assemblies compatible with Ritter & Stark’s folding mechanism which, interestingly, can be set to fold to either side.

Ashbury Int’l Wins Patent Case on Modular Rifle Chassis System

Judge Glen E. Conrad, Chief Judge of the United States District Court for the Western District of Virginia, entered a final judgment upholding the validity of Ashbury International Group, Inc.’s patent on its modular rifle technology.

SHOT Show Report: Accuracy International PSR Rifle System

Accuracy International PSR sniper system

How would you like a modular precision rifle that can shoot .338 Lapua Magnum, .300 Win Mag, and .308 Win rounds — all from the same action and chassis? And how would you like to be able to swap calibers in the field (with barrel and bolt change-outs) with just a couple simple hand tools? This kind of rifle system is not just a pipe-dream. Accuracy International’s PSR Rifle system is truly three guns in one, and it’s now in production. Watch the video to see the features of this advanced modular rifle.

Scott Seigmund, V.P. of Accuracy International (North America), gave us a run-down on the features of AI’s new PSR (Precision Sniper Rifle) modular system. By changing barrels, bolts, and magazines, the gun can shoot three different cartridge types. All the equipment (including bipod, optics, extra bolts, barrels, and mags) are carried in AI’s fitted “deployment” box.

If the full $17,200 three-barrel system is not enough for you, and you need something even more exotic — AI offers a special take-down version of the PSR rifle. Scott showed us a complete .338 LM rifle (with 20″ barrel) stowed in a transport box smaller than a typical carry-on case. Scott said the price on the take-down system has not yet been set.

New Blaser R8 Rifle with Thumbhole Stock

The unique Blaser rifle design features a straight-pull bolt with “patented Radial Locking System” of outward-expanding lugs that lock directly into the barrel. Their modular design permits Blaser rifles to be dis-assembled (with barrels exchanged) in less than one minute, using a single hex wrench. The straight-pull action allows Blasers to be cycled very rapidly by the shooter.

Until lately, if you wanted a Blaser, you had to settle for a conventional-style, solid-wrist stock. Now Blaser has introduced an ergonomic thumbhole stock with a more vertical-style pistol grip. This new stock will be offered on the Blaser R8 “Professional Success” (R8 PS) hunting rifle. Blaser claims the new stock provides a comfortable, stable hold in all shooting positions — prone, sitting, kneeling, or standing.

Blaser R8 Professional Success

The R8 PS is available in green/gray, or black/brown colors. The standard R8 PS features elastomer inlays on the forearm, pistol grip and cheek-piece. MSRP is $4,356.00. Toss in another $1100 or so, and you can upgrade the black/brown version with fitted leather inlays on forearm, pistol grip and cheek-piece. That’s a hefty surcharge for about $15.00 worth of animal hide, but Blasers were never for bargain-hunters.

Watch Blaser R8 in Action
In the video below, filmed on safari in Africa, hunter/writer Ron Spomer reviews the Blaser R8 with standard stock (not the new thumbhole). Starting at the 0:52 mark you can see how the rifle is assembled and how the straight-pull action works. Spomer’s rifle review begins as the 1:10 mark. Spomer explains that a single rifle can be fitted with multiple barrels in an assortment of chamberings/calibers.
