Tippmann A-5
(Deep in combat)
I had been using a Tippmann 98 before buying a new A-5. Not that my 98 was causing me any problems it still worked great and the upgrades I did to it were sweet. From the first day I took my new A5 out it was tearing up the field.
If you have looked at the X7 and dont want to spend the extra $$ go for an A5. I have only heard one problem from a guy I know that has had nothing but problems with his marker. But in all fairness he has added so many upgrades and "home" fixes that I am not suprised that he has had the problem hes seen.
