i believe you are referring to the striker buffer, its job is to cushion the hammer as it returns to the back of the marker, without it the shot cycle will have more kick
edit: actually i think they are asking what the black ball in the bolt itself is for, if that is the case then the answer is to make sure your bolt pin does not come out while firing. if you look at your bolt pin there is a semi-circle groove all the way around it, that is where that ball locks in to make sure the pin does not go anywhere while it is slamming back and forth
Thy spyder agressor and alpha black have very different internal parts and are ergonomically different. While The tippmann marker is a cast aluminum, split receiver, the spyder is milled aluminum, with parts that unscrew from the back. They will both shoot 300 fps at about the same rate without modification. The spyder has no forward grip and is a centerfeed (hopper is in the center). The Alpha black is larger with a handguard.
The tippmann 98 stock.
The power tube holds the valve and velocity adjuster, also it helps in redirecting airflow of the marker.
you cant use it or refill it
No, autococker threads do not fit spyders,which are spyder threaded. Any barrel marked spyder threaded will fit spyders, piranhas, and most cheap spyder clones. Also many barrels come in several threads (almost all of them have the spyder version), so a list would not help you.
The Delta elite without question. It has an apex tip and an electric hopper, and electric grip.
Although anything over 14 inches makes your marker less efficient, yes, it will fit.
yes their in California but their not professional and for it they all wear all black
some adjectives for marker could be: blue marker, red marker, black marker
The Spyder Pack has a velcro belt.
No.
Why should you not? It is a paintball field, tippmann alpha black is a paintball marker, so i guess you can. But i do not know, so if your insecure, and think they might have a reason not to allow you to use it, just dont. Or you can simply go ask, or sen them an email. HEY I AM THE GUY WHO ASKED THIS QUESTION ITS TACTICAL SERIES SO THATS Y I MIGHT THINK THEY WOULDNT WANT U 2 USE IT Y DID YOU EVEN ANSWER THIS IF U DONT KNOW YOU CAN I CALLED AND ASKED THEM
