Rebel-9 Complete Parts Kit

The Rebel-9 is the latest fully DIY 9mm carbine from ImmortalRevolt of the Gatalog. It uses a highly innovative DIY bolt design featuring a DIY extractor, DIY firing pin and DIY anti-bounce system, the first fully DIY firearm to contain these features. It uses a modified DIY MP5 magazine. It is the most advanced 3D printed gun released to date.

Our Complete Parts Kit contains all required hardware to build your Rebel-9. Because the Rebel-9 has several different options for building, we’ve split our kit up into a Hardware Kit and multiple Bolt, Barrel and FCG kits.

In order to complete your Rebel-9, we recommend you purchase:

• One hardware kit
• One Machined bolt body
• One barrel kit (either the AR9 or ECM barrel kit)
• One FCG kit (either the AR-15 or DIY FCG kit)
• One Machined Parts Bundle

Please review the descriptions below for details on the different kits.

========================

Rebel-9 Hardware Kit:

Our Rebel-9 base kit contains everything you need to build the main body and magazine for the Rebel-9, including all parts required for the stock, recoil system, printed sights, upper and lower.

Also included are all bolt completion hardware, including firing pin stock, extractor stock and ABB parts.

The Rebel-9 includes both metric and imperial versions of some parts, such as the bolt body or stock arms. All 3D Print Freedom Rebel-9 kits use the imperial version where available; otherwise, the required metric parts are used.

========================

Rebel-9 Machined Bolt Body

By far the most difficult part of building a Rebel-9 is making your own bolt. Purchase one of our bolt bodies to dramatically simplify your building experience.

The Machined Bolt Body is fully CNC’d. It is the best quality Rebel-9 bolt available.

This bolt body includes a hammer reset lug feature, meaning it can be used with both the AR-15 FCG and DIY FCG.

NOTE: the Machined Bolt Body is imperial-size (1.25″ square) and should be used with the Imperial upper.

Note 6/22/2025: these bolts have an expected one week lead time

========================

Rebel-9 AR9 Barrel

You can print a version of the Rebel-9 that takes AR-9 barrels! A modified upper and retainer system are required. These can be found in the official release package.

This product is a 5″ AR-9 barrel, the length recommended by the developer, and around which the AR-9 specific retainer is modeled.

========================

Rebel-9 ECM Barrel Kit

The Rebel-9, like the FGC-9, was designed to utilize a DIY ECM barrel. This kit contains hydraulic tube barrel stock along with all mounting equipment required to use an ECM barrel with the Rebel-9.

We sell our ECM barrel kits with barrel stock cut to the recommended 138mm. If you would like your barrel to be longer or shorter, please contact us at customersupport@3dprintfreedom.com after ordering.

========================

Rebel-9 AR-15 FCG Kit

Avoid the hassle of winding your own springs and trust in the reliability of the proven AR-15 fire control group by purchasing our AR-15 FCG kit. This kit contains all required AR-15 FCG parts, plus mounting pins sized properly for the Rebel-9.

The AR-15 FCG requires a Machined Bolt Body (with trigger reset lug) to properly function. AR-15 FCGs will not work properly with bolt bodies machined using ImmortalRevolt  jigs.

Additionally, AR-15 FCGs will not work in the Removable Grip version of the Rebel-9 lower.

========================

Rebel-9 DIY FCG Kit

The Rebel-9 DIY FCG involves a printed hammer (with epoxied weight), trigger and disconnector combined with springs wound from piano wire using a special winding jig. Our kit ships with all hardware and wire required to build your own DIY FCG, including lots of wire to wind your springs.

The DIY FCG can be used with either the Machined Bolt Body or with bolt bodies machined using ImmortalRevolt  jigs, and will work in both the normal and Removable Grip versions of the lower.

========================

Rogue-9 / Rebel-9 Machined Parts Bundle

Build the easiest, strongest ROGUE-9 / REBEL-9 around with our 3DPF Machined Parts bundle!
This bundle contains four precision machined, heat-treated key parts for your build:

• Firing pin
• Extractor
• Recoil nut
• Ejector

Traditional REBEL-9 / ROGUE-9 builds require hours of tedious filing and grinding by hand to create these parts. The Machined Parts Bundle allows you to skip the hard work and assemble the bolt right out of the box.
