Tippmann A5 with TechT Vortex Mod, nuff said. Don't forget to use some kind of grease, not marker oil. TechT Gun Sav works great. This website- rockstartactical.com has alot of stuff. For barrels, try the Lapco line, also sold on their site. Theres a ton of stocks to choose from. The Dogleg is the best.
