id buy a mag instead of a shocker
i took the liberties of doing some research for you
the mq vvalve wont be out for a while for the mag and you would just end up haveing to sell the x valve and the lvl 10 and buy a regulator
i dont know what your style is but heres what i would do
Select an X-Valve : Black
Select a Mainbody : ULE CF Black
Select a Gripframe : Single Trigger Carbon Fiber Frame Assy
Select a Barrel : ULE Barrel (ULE/Slug MB)
Trigger/Valve/On/Off Type : ULE Trigger Pull Kit/Installed
Detent (Kila-ULE bodies ONLY) : Stock Detent (no charge)
asa
$440
dont get a double trigger frame because ull end up getting a devil mag and its hard to walk a ult mag really anyway. its possible but hard, and its unrealistic in a game
then when its time to upgrade buy a devilmag kit for 550
you will have an electronic tourney legal mag that can shoot 20 bps or more if you want to set it to full auto. it will be light and more reliable than any electronic gun on the market
or just buy a devil mag right now if ur planning on the 900 shocker anyway
the problem with this is upgrade is that tourneys no longer allow gun modifications
