Picked up my first tippmann A5 used. couple issues
Just bought an A5 with response trigger, flatline, and a low pressure regulator. It also came with a bag of gear, an empire barrel kit, and a few other misc things. I bought it as a second marker to have around. I brought it home, put air to it. cocked it, shot once and didn't recock. Did it again. Pulled the bolt out the back, lubed it, retried. Failed to recock again. So in my inquiring mind I pull it apart completely thinking it has sat a few years, it needs thoroughly cleaned. Cleaning and lubing pieces as I take them apart I noticed the power tube is cracked almost the full length. I assume this is the cause for the gun to not recock after firing. So I reassembled it as not to lose any parts over the next few days while I order what i need to fix it. What would cause it to crack? Would the crack be the cause of my cocking issue? And what is the most reliable replacement for it? I have seen a few different options. Is there anything else I should look into or purchase to make this a solid marker again?
