    JT ER2s (center feed) with Rainmaker Freak adapter, fatty pump, and Stock Class feed

    Harder to find ER2-s with all the MCB goodies (and case).
    Works well (for what it is). Feels good in the hand, looks sexy.
    These definitely need some tweaking to get them to have consistent velocity throughout the 12 gram. They usually shoot hot (liquid?) when first pierced then drop off quickly with a low total shot count.
    There was a good thread here before that showed several mods that greatly improved first to last consistently that you can probably find on the wayback archive. From what I remember it was a combination of a pinhole restrictor just after the pierce pin, a “sail” on the cup seal, and using Freak inserts to slightly underbore.
    I installed the pump handle and SC feed tube, but not the Freak adapter yet.
    $60 shipped US

      Price dropped to $60 shipped!
      That is as low as this will go. Otherwise, I will keep as a fun gun/conversation piece.

            Need info on @Rainmaker's Freak mod for this marker. Did not see it in the thingiverse.
