They're all .68 cal well the TPX is nice cause you can load the CO2 in whenever then when your ready you pull the trigger and it punctures the co2 unlike the Tiberius, if you leave it in there the air leaks out a bit.
That is a secret! haha no it was way easy. I took the plasic rail they send with the gun, cut it so just the rail is there and sanded it down flush and bough some 1 min epoxy from walmart/home depot and stuck that bad boy on there. Remember if it's cold it takes the epoxy a while longer to dry.
lol if that doesn't make sense i can draw a quick diagram for ya.
t8 is better, when we played bob long he and i went head to head a few times, i was hit and called paint check. the size of splatter was less than a quarter so ref let me stay in. bob long switched to a different marker after that game
I have both a TPX and a TAC8. I like the TPX better. It is a little lighter. The grip is not as fat, feels like a .45. And the mags are a HELL OF A LOT CHEAPER. Pluss, I like the fact that the co2 doesn't get punctured until you actually need it. This alows me to keep one in the house for personal defense loaded with pepper balls. And I know the seals will be good when it's needed.
Besides the fact that you can use First Strike round in the T8.1, the TPX blows the T8 out of the water.
