no, please don't. I JUST had to file a claim with paypal against them after i ordered 3 day shipping and 2 weeks later the package never shipped. Apparently i wasn't the only one this happened to, as i've talked to many squad leaders and shop ownes and they all have a different variation on the same story. People talk. Try/call DMS from thier phone number at
www.dmspaintball.com. If they don't have it, they'll guide you to the importers for the parts. Its better than waiting several weeks for your much needed parts.
As for the manual, the forums at tactical markers do have it in PDF

Enjoy your marker. They're great!
