Lucky also do upgrades for the ion:
The lucky LBM V3 bolt (pure sex in bolt form)
Un1tec barrel kits, the only straight bore barrel kit on the market.
And the Lucky Spitfire Ion board (with optional MAC solenoid).
I am probably biased, but the bolt kit and board has completely changed my opinion on the Ion. I would shoot a lucky Ion over many markers which cost three or four times as much.
All of these parts will be in stock by Campaign cup. But I would expect them to be sold out soon after.
