Learn how to install a Plug & Play core in your SaberForge saber with this step-by-step guide. Upgrade your electronics easily—no soldering required.
Upgrading your lightsaber’s electronics has never been easier thanks to SaberForge’s Plug & Play cores. Whether you’re looking to add sound, improve brightness, or simply replace an old board, a drop-in core lets you swap components in minutes without soldering or complex wiring. This guide walks you through the entire installation process, from gathering tools to testing your saber. We’ll also highlight a few compatible parts like the Bushido Mk2 (Wrapped) and the Eris Mk2 to show how these cores integrate with popular hilts.

Before you begin, make sure you have the correct Plug & Play core for your saber model. SaberForge cores are designed to fit specific hilt styles and blade sizes. If you’re unsure, check the product description or contact support. The steps below assume you’re working with a standard SaberForge hilt that uses a threaded chassis system. Let’s get started.
What You’ll Need
Before diving in, gather the following items: your SaberForge hilt (e.g., the Bushido Mk2 (Wrapped) or Eris Mk2), a compatible Plug & Play core, a hex key set (usually 2mm or 2.5mm), a small flathead screwdriver, and a clean work surface. Optional but helpful: a soft cloth to protect the hilt finish, tweezers for handling small wires, and a multimeter for testing continuity. Having everything ready will make the process smooth and prevent lost screws.
Most SaberForge hilts come with a retention screw that holds the core in place. You’ll need to remove this screw before inserting the new core. Keep it in a safe spot—you’ll reuse it later. Also, ensure your blade is compatible with the core’s LED module; standard 1-inch blades work with most cores.
- Always work on a soft, non-abrasive surface to avoid scratching your hilt.
- Take a photo of the original wiring orientation before removing anything—this helps if you need to revert.
Step 1: Disassemble the Hilt
Start by unscrewing the pommel and sliding it off the hilt. For hilts like the Bushido Mk2 (Wrapped), you may need to loosen a set screw on the pommel first. Once the pommel is off, gently pull the chassis (the internal assembly) out of the hilt. If it’s stuck, use a small screwdriver to gently pry it from the emitter end. Be careful not to damage any wires.
With the chassis removed, disconnect the battery (if present) and note how the existing core is seated. Most cores are held by a single retention screw. Remove this screw and slide the old core out of the chassis. Set the old core aside—it can be reused in another hilt or kept as a spare.
- If you have a hilt with a wrapped grip, like the Bushido Mk2 (Wrapped), avoid twisting the wrap during disassembly.
- Keep all screws organized in a small container or magnetic tray.
Step 2: Insert the New Plug & Play Core
Take your new Plug & Play core and align it with the chassis slot. The core should slide in easily—do not force it. Make sure the LED module faces toward the emitter end and the soundboard (if present) is oriented correctly. For cores with a recharge port, ensure the port aligns with the hole in the chassis or hilt body. Once seated, replace the retention screw to secure the core.
Now reconnect the battery (if it was disconnected) and gently push the chassis back into the hilt. Start with the emitter end, then slide the pommel end into place. Screw the pommel back on, tightening it firmly but not overtightening. For hilts like the Eris Mk2, you may need to align a keyway or notch—check the hilt’s manual for specifics.
- Double-check that no wires are pinched between the chassis and the hilt wall.
- If the core doesn’t fit, verify it’s the correct model for your hilt.
Step 3: Test and Finalize
Before fully reassembling, install a blade and power on the saber. Test all functions: ignition, color change, sound fonts, and motion effects. If something doesn’t work, power off and recheck connections. Common issues include loose battery connectors or reversed polarity. Use a multimeter to verify voltage if needed.
Once everything works, tighten all screws and give the hilt a gentle shake to ensure nothing rattles. Your new Plug & Play core is now installed! Enjoy your upgraded saber with improved performance and features. For additional customization, consider pairing your core with accessories like the Metal Blade Plug 1.3 or a new blade.
- Test the saber with the blade fully inserted to ensure proper LED alignment.
- If you encounter sound issues, check the SD card seating in the core.
Installing a Plug & Play core in your SaberForge saber is a straightforward process that opens up a world of customization. With no soldering required, you can swap cores between hilts or upgrade to the latest features in minutes. Whether you’re outfitting a new build like the Bushido Mk2 (Wrapped) or refreshing an older hilt, a drop-in core is the easiest way to keep your saber combat-ready.
