MERKEL RX HELIXMerkel has created a truly revolutionary bolt action that cycles in half the length of the conventional system. While the RX Helix is a straight-pull rifle, it retains the strength of a rotary bolt head with seven locking lugs, as well as a fully enclosed, hard-anodized aluminum action housing. The RX Helix’s linear motion of the bolt handle is transmitted to the bolt head by way of a revolutionary transmission gearing system.
