Cheaper, easier, less hassle to convert it to a spring piston rifle but wait a bit and mikeyb will be in to confirm what I just said.

...Then there is this: https://www.ebay.com/itm/173267944333It is more expensive than either Hatsan option and would take quite a while to get here....
My personal opinion is that ebay dual spring solution is a slick marketing waste of money. The small spring is far too weak to add any significant energy. The dual counter wound concentric springs won't bind, but they certainly can't work as good as a single properly fitted spring & guide. IMO a GOOD QUALITY single main spring with a full length and properly fitted spring guide will provide the best coil spring performance.I'd try installing the NP1. Will post photo of my Edge NP1 spacer shortly.
