A better marker, strip down a Tippmann a5, build as indicated, if you can't do it all at once, do it in this order: Dual Trigger, E-grip(or response trigger), x7 hopper, quickfeed hopper top(not shown), squishy paddles, flatline barrel, drop foward expansion chamber. Replace crappy plastic parts as required(meaning, drop the marker, the cocking lever or something breaks) with aluminun. Buy a JT Proflex mask and other items as your discretion. Oh yeah, this used to be my marker, I sold it for 80$, I now carry two of [url=http://www.tippmann.com/TiPX_Pistol.aspx]these.[/url] That old a5 chewed up way to much paint for what I was doing.
