The Merkel Helix Black version with removable sights and muzzle thread M15x1. Translated straight-pull repeater in which the linear movement of the bolt handle is transferred to the bolt head in a ratio of 1:2. He runs in the Merkelsystem in the specially developed helix track moves smoothly and quietly into the lock. The repeating path is very short due to the translation and therefore makes a very quick repeating process possible. The result is quick target acquisition and a precise follow-up shot.

For repeating at the stop, one of the rotating head locks was adapted to linear repeating. Disturbing rotational or tilting movements have been reduced to a minimum thanks to the revised system. The bolt handle is located directly above the trigger, which makes repeating intuitive.

The proven straight stock in the style of the African rifles gives the movements the appropriate support. The safety aspect is very important to the Helix. In addition to the manual tensioning system that is located on the butt neck, the system is only tensioned with thumb pressure immediately before the shot and then relaxed again, so the risk of an unintentional shot being fired is reduced to a minimum. In addition, the closed system box protects against contamination and external influences avoid.

The rifle's patented hammer system with the joint-driven hammer always delivers the maximum ignition energy. Merkel, always a manufacturer who has paid attention to foreign hunting and practice, once again attach great importance to the weapon's good transportability. The rifle is take-down capable and can be dismantled without tools. A barrel change can also be carried out without tools. The weapon can be dismantled to a very small size in just a few steps. The barrel, bolt head and action are connected by a coupling mechanism that can be released by a single lever.
