This product will try to give you the best of both worlds if you play paintball and airsoft. But you will have problems for the high fps. We know some will snicker about this, but heck, give it a chance to prove itself against other HPA power airsoft guns like PolarStar or the real classic airsoft guns... "This converter is revolutionary for both paintball and BB guns. Its 600 fps power is like no other 6mm BB gun on the market. And because it fits on your current Spyder gun, you only have to trick out one weapon, not two.
