ROLS

The new, patented bolt-action system CLS® (Chapuis Locking System) offers a total locking area of 260 square millimeters, making it one of the largest and safest in the
industry. Our testing has confirmed that it can withstand pressures upward of 8,500 BARs, or 123,000 PSI.

A BARREL WITH INTEGRAL LOCKING SYSTEM

The heart of the in-line action is a locking ring consisting of seven segments—as part of the barrel. These segments seesaw on a central fulcrum to firmly grasp the bolt head
upon locking the action, or to release it upon opening.

AN INDESTRUCTIBLE LOCKING MECHANISM

The bolt lever guides the position of the blocking sleeve, which glides along the boltbody. This sleeve guarantees the positive and vault-like locking of the bolt head. When
the seven segments of the locking ring are opened or closed, they are held in position by this sleeve: once the action is pushed forward all the way home, the segments are
blocked in the locked position, preventing any accidental opening of the action.

The ROLS® rifle has a separate cocking device, with perfectergonomics. The cocking device controls a piston that compresses the firing pin spring for firing, allowing also decompression of the spring for decocking. A hunter can then hunt safely with a chambered cartridge. In the un-cocked position, the bolt remains secured, thus preventing any unwanted bolt movement.

The cocking device is a thumb-pushed cocking lever which has been extensively tested so that decocking your rifle is the most simple, safe, and rapid as possible, even with scope and ready to fire, should you decide at the last moment not to shoot. In this case, on some of our competitors rifles, it is not always easy to slip your thumb under the scope to press the cocking device. On the ROLS® it is easy, since a slight pressure exerted with the thumb on the button located on top of the cocking lever releases it, decocking the rifle.

The levered bolt-handle is located just above the trigger. Cycling the action becomes intuitive and very quick.

Safety was the essential objective when developing this rifle.
As long as the bolt-handle lever is not fully pushed into a vertical position and the bolt head is not totally locked, a passive safety device prevents the firing pin from striking the primer of the cartridge. An unintended discharge is thus made impossible.

Our goal was to provide an in-line feeding system, so as to avoid any feeding problems.

With this high capacity rotating magazine (4 rounds + 1 for standard calibers, 3+1 for magnum calibers) the cartridges are lined up with the chamber.

Reloading is made smoother and easier. We also invented a magazine lowering device, controlled by the bolt. During the forward movement of the bolt shaft, the magazine lowers into the receiver, removing any impediment of the cartridge between magazine and chamber.

The barrel is held in a sleeve, resulting in perfect headspace when the two are assembled. This sleeve has a recoil lug machined with a high degree of precision, less than 1/100 of a millimeter, locking on a steel-made bedding carried by the receiver.

This precision allows the perfect changing of barrels with exceptional accuracy on the first shot. Changing the barrels is made by screwing/unscrewing the screw under the receiver, with the provided wrench.

The development of the detachable, rotating magazine of the ROLS® took many months and a patent is pending.

This magazine is located over the trigger guard and trigger, keeping the overall length of the rifle to a minimum. It can beremoved in a simple two step procedure.

First, a release button is pressed which opens the trigger floorplate. In a second step, the magazine is ejected. This two-step device is intentional, so as to prevent any unintended ejection of the magazine. But if needed, a quick change of magazine is possible by maintaining pressure on the release button; the floorplate opens and the magazine is ejected simultaneously. You can then reload.

For rapid reloading, especially on driven big game hunts when many shots are fired, it is also possible to reload the magazine from the top of the receiver. For safety, when the trigger floorplate opens, the rifle is automatically decocked.
