Merkel's answer to the new Blaser R8 is the Merkel RX.Helix. This takedown rifle makes use of a straight pull bolt action.
Its name is derived from the bolt's rotation system. The bolt is rotated in a helical motion at a 2:1 ratio (of forward motion to rotational motion). Apparently this allows for a smooth and fast bolt operation. This video shows the rifle being shot at 1 round per second. Pretty impressive!
The gun will be available chambered in 222 Rem., .223 Rem., .243 Win., 6.5x55mm SE, .270 Win., 7x64mm, .308 Win., .30-06, .308 Win., .30-06, 8x57 IS and 9.3x62. The magazine capacity is 3+1 rounds. The rifle weighs 6.4 lbs.
