Discovery mod with maurader parts?

The Maurader tube is 1 1/4" o.d, the Discovery is 7/8" as is the 22xx, 1701p, 1720t and Maurader pistol. Some of the co2 adapters work/fit but need additional screws to secure it to the original tube if air pressure is increased above 1500psi. I would call jdsairman ( 732 500 7270 ) and talk to John Di Stefano to get his input, as he sells the adapter, tanks and regulators.
