Straight-Pull Strasser RS14 Hunting Rifles — Austrian Excellence

strasser RS14 Evolution rifle

We like to see innovation in rifle design. One of the more interesting designs on the market is the Strasser RS14, an Austrian-engineered rifle featuring a slick, straight-pull bolt. With a quick rearward pull, the bolt cycles back. You may be familiar with the Blaser rifle — that requires the bolt handle to be moved in an arc. By contrast, with the Strasser, you literally pull straight back on the short-stroke bolt handle. After the handle moves about 60 degrees rearward, the bolt unlocks and then you can move the entire bolt assembly rearwards through its full motion, cycling the cartridge. The action is very smooth and very fast. Check it out in this video, at the 40-second time-mark:

The action is ambidextrous. The manufacturer can supply either a right-hand bolt or a left-hand bolt. That’s correct — you can switch from righty to lefty simply by swapping the bolt. Very clever.

Again, you can see the smooth, straight-pull bolt in the video below. The Strasser also offers a simple system to change barrels with just an allen key and another simple tool that nests in the fore-arm. The barrel-swap process is shown in this video starting at 1-minute mark:

One of most impressive features of the Strasser is the ease with which you can change chamberings — from small cartridges all the way to to full-size magnums. The owner can swap barrels in a few minutes. What’s more, the Stasser’s quick-change bolt face allows users to quickly and easily switch between small, standard, and magnum bolt face. That way you can shoot anything from .222 Rem up to .375 Ruger with the same RS-14 rifle. Here are the chambering options offered by Stasser (with Walther-made barrels):

Small Caliber (MIN): .222 Rem., .223 Rem., .300 AAC Blackout
Standard Caliber (STA): .22-250 Rem, .243 Win, 6XC, 6.5 Creedmoor, 6.5-284 Norma, 6.5×55 SWE, 6.5×65 RWS, .270 Win, 7×64, 7mm-08 Rem., .308 Win, .30-06, 8×57 IS, 8.5×63, 9.3×62
Magnum Caliber (MAG): 7mm Rem Mag, .300 Win Mag, .338 Win Mag, .375 Ruger

The latest RS14 Evolution features a Picatinny rail on the receiver. USA buyers can choose between an RS14 with high-grade Walnut stock or the Tahr model with a grey, laminate stock. Both types have a detachable trigger module, that allows easy adjustment of pull weight.

This has a good video showing how the straight-pull action works: “Locking is by four quadrants around the bolt head, which are forced out into a ring in the chamber extension similar to the Blaser’s multi-collet system. When cocked and locked the bolt handle sits forward at an angle and pulling it back allows the lugs to contract so the action can be opened. The head is fully supported and shows a plunger-type ejector.”

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.

Blaser Offers Easy Barrel Exchange and Fast Cycling

The Blaser R93 is a unique rifle, employing a patented straight-pull bolt with radial locking system. Using a pivoting short-throw bolt handle, the bolt slides straight forward and back to feed and eject ammunition. It’s simple and fast. The Blaser R93 was designed as a modular system. This means the bolt can be changed from right-pull to left-pull in seconds, and barrels can be exchanged quickly and easily. This makes the R93 extremely versatile — invest in one action and stock and you can shoot a multitude of chamberings. Factory barrels in 28 different calibers are offered. A Blaser barrel can be switched in less than a minute, using a simple T-handle wrench (see Video below).

While most Blasers sold in America are hunting rifles with conventional-style stocks, Blaser also makes a model for CISM 300m competition, a tactical model, and long-range target model (LRS-2). These all feature an aluminum receiver block, synthetic sub-chassis with cantilevered fore-end, and larger-capacity magazine. The rear section of the stock has an adjustable cheekpiece and butt-plate. Shown in the video below is a Blaser R93 LRS-2 fitted with bipod and muzzle brake. Note the very low recoil of the 6mmBR cartridge when the braked gun is fired. Along with the 6BR chambering, the LRS-2 is offered in .223 Rem, 6.5×55, .308 Win, 300 Win Mag, and .338 Lapua Magnum.

One of the Blaser’s best features is the speed with which the bolt can be cycled. Just pull the bolt-handle back to open the action and eject the brass, then slide the bolt handle forward to close the bolt. Compared to a conventional bolt, the Blaser requires minimal hand movement. Once you get the hang of it, you can cycle the gun extremely fast. The video below show a hunter practicing with a .308. Watch how quickly the bolt cycles–and this shooter could probably shoot even faster if he maintained his cheek-weld.
