Aftermarket Parts
What actually exists in the Ion aftermarket — what each part changes, who makes it, and whether it's still something you can buy today. Built one category at a time, each one researched and sourced rather than recycled from memory.
Reading the parts pages
Every part on these pages gets its own card. The colored dot in front of each name is its availability status:
- Currently sold — confirmed in stock at a real retailer, including leftover stock from makers that have since closed.
- Discontinued — no longer made. What's left is used or new-old-stock (NOS).
- Unclear / not confirmed — I couldn't verify its status, or haven't been able to confirm exactly what the part is yet.
Hover over or tap a dot for the specific status behind it. A part name with a arrow links to a real listing — for discontinued parts that's a reference page rather than something you can still buy, and the card says so. Availability changes constantly, so always confirm on the seller's own page before you buy.
The Ion aftermarket today
Smart Parts closed in 2010, and most of the Ion's aftermarket came from the custom-parts scene of the mid-2000s — makers like NDZ, Element, Trinity, and Custom Products (CP). Most of them have since moved on: NDZ makes no paintball parts at all now, and CP closed in early 2026. A handful of parts are still made or still sitting in stock at retailers, but most of what's on these pages is used or NOS only. That's why each card records who made the part and where things stand, not just what it does.
Buying used Ion parts
In my experience, eBay is the best place to find them. The MCB forums (mcarterbrown.com) are another good source, along with Facebook groups like Smart Parts Paintball Support Group, Smart Parts Ion BST, and Smart Parts Appreciation Group.
Before buying a part listed for a different model than yours, check Parts Interchange — plenty of parts swap freely across the Ion family, but a few don't, and the Epiphany differs most often.
