Barrel profile Helix

Every rifle barrel has the grooves and fields on the inside, required by the calibre. Calibre and twist are perfectly adjusted to each other – this results in the high precision. But also the outside barrel profile is more than a design element. Next to the standard, round barrel, Merkel manufactures different rifle barrels: This, inter alia, includes octagonal barrels, semi-weight barrels and fluted barrels. Utilising the different profiles, vibration behaviour, warmth distribution and weight can be influenced. All barrels have a similarity: they are exclusively cold forged in the company with the experience of the manufacture – made in Suhl, Germany.

Standard barrel

The standard barrel is a pragmatic and universalist, it combines good vibration behaviour and little weight with optimal tuning to the twist rate suitable to the corresponding calibre.


The little bit thicker 19mm strong semi-weight barrel is heavier: The consequence of the additional weight – at the same barrel length – is an optimal weight distribution, more stability while shooting and finally a higher shot precision hit ratio. With increasing mass, the heat accumulation properties of the barrel increase via the thermic mass; it also decreases recoil through mass.

Fluted barrel

An optical highlight with function: fluted barrels look good, save weight and cool down quicker.

i-Sight System

The i-Sight system offers the needs-orientated and individual configuration of the Helix’s’ open sights. As a Standard, the i-Sight bead is mounted in the front of the two barrel boreholes, it can, however, be easily switched to the rear if the muzzle thread is needed. Furthermore the front and rear sight can be detached completely, to use an over-barrel suppressor for example.
