Question on Nelson Based Pumps....

[D-CeLL]

I'll be getting an Armson Pump which leaks down the barrel (cup seal is most likely bad). How different are the internals between different gun makers products like say a Trracer/Maverick, Phantom and what ever else is current? I'm just wondering where to get spare seals from and what not.
Thanks....

in all honesty they are all practicly the same

the Maverick, hornet, traccer are the EXACT same gun except where the pump arm goes. the armson should be similar to them. phantoms are a little differant but parts should still work
