I took my new M305 to range for the first time today and had a couple of issues. The rifle would not cycle right from the start, I checked the spindle valve and it was in fact not in the vertical position. I repositioned the valve to the vertical which was done with almost no effort and tired again. Still the rifle would not cycle (no movement at all) so I had a closer look at the spindle valve. A small push from the opposite side and out came the spindle valve
. I am guessing by the second hole in the valve that there should be some type of cotter pin or retainer to secure the pin? Any help is much appreciated.
