How the Ion, Epiphany, 2.0, and XE actually happened →

Ion 1.0 — stock configuration

Ion The original — most common, most parts on the used market.

Full-marker shot, Ion 2.0, stock configuration

Ion 2.0 New regulator, ASA, feedneck, and power button — body stays the same.

Full-marker shot, Ion XE, stock configuration

Ion XE Bolt-out-the-back, one-piece firing assembly — its own body and feedneck.

Full-marker shot, Epiphany, stock configuration

Epiphany Fire chamber volume inserts, higher pressure, distinct body and trigger.

Not sure if you've got an Ion, Ion 2.0, or XE? Here's how to tell — XE is the easy one to catch at a glance, since the body and feedneck both look different. Ion 1.0 vs 2.0 takes a closer look: the regulator is the most obvious tell, then the feedneck, then the ASA fitting. (Epiphany's easy to spot on its own — see the tile above.)

Why ReIonized

100+ Ions in my own collection — and I've owned one since they first came out.

Smart Parts closed in 2010, but the Ion never really went away. It's still one of the most common spool-valve markers on the used market, and still one of the least documented in one clear place — scattered across old forum threads, a few aging sites, and whatever survives on YouTube. ReIonized pulls it together, written from taking these markers apart myself. More about me →
