Jake yes Magnus does make its stinger in 4 blade. And I do like them and killed a bunch of deer that dropped within sight. They also have a lifetime guarantee which I have used and got new BHs without question. My concern with them and why I moved away from them is that they are made of an alum. alloy and are not really that strong. They fly great when new. But shoot them into a block type target a few times and it the block is on an angle a bit and they hit wrong, your next shot may go to the great beyond.
Grouch, why don't you go with the Muzzy Phantoms? They are all steel and they fly great also.
