The stock one does work fine, but looks a bit waft, is made from cheese (ask phil-boy what happened when he tried to remove one of his!) and the lever flapping around when you don't have a hopper in place is REALLY irritating (to me at least!). It just strikes me as odd that they've not included the Nano in these PL markers when they've already added the Redline & Superfreak, would make a perfect package - unless they were trying to keep costs below a certain price point.
