Very cool.I had recently posted in another thread, that I love my K31 for its straight-pull bolt, and thought more modern guns/manufacturers should offer it, as it is REALLY fast and comforable compared to the standard turn-bolt, IMHO.Interesting to see someone else feels the same and is actualy making them (and in a top of the line tactical type rifle no less, makes me feel a little cutting edge and uber-tactical...)Now if people would make them in rifles us poor people can afford....The bolt is neat. There is no rotation, its just a straight pull back.
