Here are many of the parts to build an "ego/etek" mag. If you are not familiar with google "egomag" it is an awesome mod you can do to any xvalve/rt/emag valved marker. There are plenty of "how to's" showing how to do this mod on the forums. I just don't have the time or the patience to do it myself. $50.00. I use Paypal.
Included:
MPA-3 ram
Etek Aurora frame
SMC S070C-SDG-32 solonoid
Etek Eyes
