this is a nice addition to the bushy upgrades. There was no "no rise" prior to this one. However, there has been one new no rise out, almost right after this one was released. check out www.tantrumpaintball.com for info on the clamp no rise.
The rise uses o rings in the interior to hold your hopper on. Little tough to get it in there, but it STAYS in tehre once it gets in. Really nice for me, since my halo would rotate a bit on the stock rise. you can also take the orings out if you like.
only have 2 complaints. It only comes in black and silver, and it kidna looks funny. Its not ugly, but its not the coolest. It would prolly look a lot cooler on the new bushies, however.
damn nice product from vaporworks. these guys know what they are doing. Just too bad it took so long to get this out on the market.. If you are looking for a nice no rise, look into this one. its a nice buy for the money. Only down side is the cosmetics... taht and getting your stock feed tube off. it was a pain.
