my buddy had a military rifle.....i want to say a.....swiss rubin or something of the sort.....it was a neat rifle.....cheap too...100-150 bucks i think.....o would bought one but i think it was an odd ball caliber....but man it was accurate....free hand 40yds never shooting the rifle i was blasting shotgun hulls off the target stand every time with open sights.....it was a neat gun....not sure if its something youd be interested in...if your looking for a quick action why not a pump?? again..not sure what your looking for or why you want a straight bolt....just throwing out an idea if quick shooting is what you want.....
