This Sunday we feature the German-crafted Merkel RX Helix with straight-pull bolt. We shot the Helix a few years back during Media Day at the Range. One notable difference between the German Merkel and the Austrian Strasser, another straight-pull rifle, is the bolt travel. During cycling, the Merkel bolt stays completely inside the action (see video below at 00:30). By contrast the Strasser bolt moves pretty far back, outside the action. For some folks that makes the Helix better for fast follow-up shots. All we can say is that Merkles and Strassers BOTH cycle way faster than conventional bolt-action rifles.

Merkel RX Helix Range Report

One of the most innovative rifles we have ever shot was the Merkel RX Helix, a very impressive piece of rifle engineering. Merkel claims the RX Helix is the fastest-cycling centerfire bolt action in the world. We can’t confirm that claim, but the Helix certainly cycles faster than any other centerfire bolt-gun this Editor has ever tried. (Yes, a Fortner biathlon action can be worked more rapidly, but that’s a rimfire). Both Jason and I really liked Merkel’s RX Helix. It balances well, the action is smooth, the wood is gorgeous, and the overall design thinking that went into this German-engineered take-down rifle is very impressive. The Helix’s universal-sized action lets you shoot anything from a .222 Rem to a .300 Win Mag with the same gun. And — get this — you can really swap barrels (and change bolt heads) in a couple of minutes with no tools, employing a dead-simple bolt-release lever concealed under the push-button-released removable forearm. (Watch VIDEO BELOW to see Barrel Swap procedure).

Rotary 7-Lug Bolt
While the RX Helix is a straight-pull rifle, it retains the strength and safety of a rotary bolt head with seven locking lugs that seat in a barrel extension. Unlike a Blaser, the RX Helix has a fully-enclosed action housing. That’s an important safety feature. Moreover, since the RX Helix employs a closed action, the bolt body doesn’t travel outside that action. This means the shooter can maintain his cheekweld with an eye on the target as he cycles the bolt.

The RX Helix’s linear (back and forth) bolt-handle motion is transmitted to the bolt head through a 1:2 ratio “transmission” gearing system. This allows smooth and fast cycling without the rotational or tipping movement found on other straight-pull, bolt-action rifles, such as the Blaser.

The Merkel linear-movement action cycles exceptionally fast, which allows for faster follow-up shots — a good thing if you’re hunting dangerous game. The RX Helix features a manual cocking lever on the tang and a direct trigger system. And here’s good news for southpaws — though Merkel does not make a dedicated left-hand version, lefties can very easily use their right hand to work the bolt while maintaining cheekweld. That may sound awkward, but with practice, it’s actually pretty efficient.

Fast, Easy Disassembly and Barrel Exchanges
The video below shows how the Helix can be disassembled (for cleaning or transport) in a matter of seconds WITHOUT TOOLS. The forearm slips off with the push of a button. A short lever on the left side of the action holds the barrel. Simply rotate the lever and the barrel (with bolt head) slips off. That’s it — in 30 seconds the rifle is apart, and you don’t even need an allen wrench as with a Blaser.

The RX Helix has a universal action length that covers calibers from .222 Rem to .300 Win Mag. Changing calibers (or chamberings) takes less than a minute with the appropriate barrel, bolt-head and magazine. Weaver rails are integrated into the action, and iron sights with three-dot rear and one-dot front fiber-optic inserts are standard.

The RX Helix is available with a standard black finish as well as four levels of design — Arabesque, Wild Boar, Spirit, and Deluxe. An all-carbon-fiber version was also available either with or without a carbon-wrapped barrel. The RX Helix comes in a wide range of calibers including .222 Rem, .223 Rem, .243 Win, 6.5×55 SE, .270 Win, 7×64, .308 Win, .30-06 Sprg., 8×57 IS, 9.3×62, 7mm Rem Mag and .300 Win Mag. Barrel lengths vary according to caliber, and barrels, bolt-heads and magazines are available for caliber changes. EuroOptic sells the Merkel RX Helix, but most models are back-ordered.

There is a new straight-pull hunting rifle coming to the USA. No, it’s not a Blaser, it’s a Strasser, made in Austria (not Germany like the Blaser). The new Strasser RS-14 is a premium hunting rifle with some very remarkable features. The trigger exchanges as a module, without tools. The entire barrel assembly can be swapped out in five minutes — and you can easily change bolt head so this rifle can shoot everything from small varmint cartridges all the way up to .30-Caliber Magnums.

The new RS14 Evolution, specially designed for the U.S. market, is a straight-pull, bolt-action rifle that features a removable trigger pack and the ability to easily adjust trigger weight without tools.

The quick-change bolt face allows users to quickly and easily switch between small, standard, and magnum bolt face. It comes with an integrated Picatinny rail on the receiver. USA buyers will be offered two different RS-14 models, one with grade E Walnut stock or the Tahr model with a grey, laminate stock. The first 100 of each model will be serial numbered to signify a special edition just for America. This rifle is a premium product — we expect the asking price to be in the $2500.00 range. For orders and inquiries, contact the U.S. importer, International Firearms Corporation (IFC).

You’ll find a detailed review of the Strasser RS-14 on TheTruthAboutGuns.com.
Here are highlights:

“A user can swap Strasser’s barrel and bolt face in under five minutes to accommodate new calibers, from short-action plinkers like .223 Remington to full-belted magnum loads like .300 Win Mag. You can choose your favorite calibers and different barrel and muzzle profiles.

Straight pull bolts are the quickest to operate. A traditional bolt-action rifle requires four movements: up, back, forward, down. The RS-14 requires only two: straight back and forward. That ‘extra’ speed could make all the difference in the field…

The RS-14’s bolt is a thing of beauty. Perfectly machined with a satin-smooth finish, it glides back and forth in the action’s channel. The over-sized bolt handle gives the operator a large target to grab when reloading.”
