The A5 is internally the same as the t68, but has a cyclone feed that allows balls to be fed faster. It also has a fore-grip, which is useful in holding the marker. I would value these things at more than ten dollars, which is the price difference.
The tippmann A5 is supposed to be used in paintball.
Since the Diablo is almost a hundred dollars more, you will spend better money getting an e grip alpha black. Diablo does not have a reputation for well built markers.
It can zoom up to 32 times normal range and can be adjusted horizontally and vertically.
This statement is half true but half untrue. The tippmann A5 and 98 custom do indeed have different threads. But after the A5 tippmann made the X7 which has identical threads to that of an A5. Because of this a barrel with "Tippmann A5" threads, will fit on a tippmann x7, but will not fit on a tippmann 98 custom.
Yes, the standard barrel has A5/x7 threads, but you can order it with 98/Alpha black threads.
No. the thread pattern is NOT the same
Yes.
There are no manufactured ones
There are no manufactured ones.
No It uses a screw on the top that goes into the a5, the bt4 uses a rail system. Besides the Bt-4 already comes with a better hand-grip then the A5.
No, the screw set is off and there is holes for the cyclone feed.
