Consistently blows low side rupture disk
I purchased this tank at the end of April, first of May 2007. I filled it up, put it on my marker, and dry fired it five or six times. It blew the low side rupture disk.
Crossfire took it in under warranty, and supposedly replaced the regulator and sent it back to me. I had to pay shipping back to them. This time I got one good weekend out of the tank, and it worked well. About 2000 rounds. The following weekend, I put about 200 rounds through it and it blew the low side rupture disk again.
I sent it back to Crossfire again, I payed for shipping again, and they sent it back to me claiming to have replaced the regulator again. I filled it up when I got to a field to play, and went to chrono. It lasted 3 shots before it blew the low side rupture disk. Three shots.
This time Crossfire payed to have it shipped back to them, and supposedly replaced the reg again. It came back looking beat to hell, the threads were flat on one side from either dropping it, or tool marks. I religiously kept the thread saver on it that came with my tank. The tank was also RETURNED TO ME WITH A BLOWN RUPTURE DISK!
The local Crossfire dealer, who is not where I purchased the tank, offered to swap it out if Crossfire would accept the bad tank on return from him for a store credit. Crossfire refused this option. They want me to send it back to them (on their dime at least) for a FOURTH TIME!!
I've owned this tank just over a month and a half, and its been usable one weekend.
Crossfire has shown no competence in their ability to produce a quality product.
Sounds like Crossfire has a bad batch of burst discs to me. Maybe try getting one from your local proshop and putting it on there yourself. If that one blows, then there's probably something wrong with the tank. If not, Crossfire's just got some bad low-side burst discs. In any case, picking up a burst disc has got to be cheaper than shipping it back to Crossfire. Besides, you'll know immediately what's going on by what results you get.
I just find it hard to believe that 1800+ psi is getting through an 850 psi regulator with that kind of repeatability. That's what makes me suspect bad burst discs.
