No, they fit in the same place. Besides that, putting them both on wold defeat the purpose of either of them and would not increase speed. The E-grip is supposed to use battery to make automatic fire easy, where the response trigger allows you to use a form of auto without needing a battery by using Co2.
No. None of the kits will fit.
No. they have two different receivers.
No, the mounting screws are different, it will not fit the 98. There is a 98/USarmy cyclone feed made that will fit.
No. The trigger assembly for the a5 is set up very different from the 98 custom.
An E-trigger is the Tippmann Board, not an actual trigger.
Not unless you get the handle adapter and drill a hole in the carry handle.
You unscrew the screw on top of them, drop in the new ones, and put the screw back.
i love the word response
unscrew the old one counter-clockwise, then screw in the new one, threads first clockwise.
Yes. The A5 stealth comes stock with a top rail therefore a BT or Tippmann sight can be screwed on.
No
As far as i know there is no markers specified for sniping in paintball. That's sorta reserved for airsoft. But a Tippmann marker with a flatline (X-7 or A-5 preferably) should do the trick. The flatlines put backspin on the balls as they go out increasing the range, and Tippmann is the only company that makes them and they only fit on there guns.
