Just install the Egrip and the expansion chamber.
Is what you can't do, the egrip frame comes too close to the tombstone to allow for an expansion chamber to fit, I'm trying to find a solution, did anyone find one yet?
The tippmann 98 egrip.
No, it is slightly different shaped.
No, their e-grip setup is slightly different and will not fit. Also the Alpha black's egrip upgrade is 30 dollars less.
Yes, the tippmann 98 and the tippmann custom are the same marker, therefore the threading of the barrel will be the same.
The 68 does not have a removable barrel.
98Shooter: I wouldn't recommend anything from the US Army series. Some of Tippmann's less desirable work, though they look cool the distance isn't near other guns. My 98 Custom outdistances it 6/10. If you are looking for woodsball i wouldn't recommend it, and i don't play speedball so i couldn't tell you for that.
No, it will not fit.
no, they are made by 2 different companies
CO2 or HPA will work fine with it
It will fit both of them.
the one it comes with is good but most tippmann barrels should work
No, but any drop forwards with the standard two hole fitting will work.
