Underlever kit - X22 - (Magpul X22 Hunter stock) - PRE-ORDER
Pre-order - Batch 5 expected delivery in early 2025.
All Batch 5 underlevers will be produced using the split-assembly method where the lever is produced in 2 halves which are then permanently bonded together with steel pins, so they will look slightly different to the pictures shown, with a thicker area under the trigger guard. Function and strength is unaffected.
This Underlever Bolt-Action conversion kit has been specifically designed to be compatible with the Magpul X22 Hunter stock:
IF YOU DO NOT OWN THIS EXACT STOCK MODEL, DO NOT PURCHASE THIS UNDERLEVER. This design has not been tested to fit any other style of stock.
Huge Launch Event, Demonstration and Testing video!
This kit is a "2nd tier" upgrade kit. It builds on top of several other parts and modifications that must have already been done to your KC-02 before you can install the Underlever. If this is the first time you have seen this kit, we highly advise you to research it before purchasing so you understand how it works and what you need to go with it. This is considered an "Expert Level" kit for people already familiar with working on their KC-02. Here's an example video of a full Underlever KC-02 build process.
Underlevers are NOT COMPATIBLE WITH M4 HPA MAG ADAPTORS. The lever will collide with the magazine.
BUT they are compatible with MP5 mag adaptors like the Tanuki kit :-) as long as the magazine does not protrude backwards from the adaptor.
THE UNDERLEVER ALONE WILL NOT GIVE YOU BOLT ACTION OPERATION. Using it with a standard semi-auto blowback gun will likely result in catastrophic damage and injury. Blowback must be disabled.
The recommended way to install this Underlever also requires a Solid-State Bolt and a Genesis Hop Unit.
If you want to change your gun back to semi-auto operation then you can simply remove the underlever and swap bolt assembly and charging handle to change the gun back to semi-auto operation as normal. Takes about 5 minutes to do with just 2 tools (4mm allen key and M3 nut driver (linked below)).

This Underlever kit consists of:
- Underlever Main hand loop
- Underlever pivot clamp
- Triple-bolt bar linkage
- Sliding-slot bar linkage
- Bolt-link charging handle adaptor
- 3 high-grade metal-shielded ball-bearings for the pivot points
- Assorted nuts and screws for assembly
- Optional rubber blanking bungs to plug the safety pivot hole when you remove the lever if you want to use semi without dust going into the trigger.
The kit is produced in 7075 aluminium, and is available in our usual range of anodised colours and patterns.
Recommended Special Tool
In addition to the usual selection of Allen keys and tools used for working on your KC-02, we highly recommend adding an M3 (5.5mm) wrench or driver to your arsenal for use with tightening the small M3 lock nuts on the Underlever, because if you try to do it with pliers or an adjustable spanner, you will probably scratch the anodising on your underlever parts and make it look bad, so buy one of these kind of tools to avoid that cosmetic damage:
or something gucci like this:
Wera Insulated 5.5mm Hex Driver
I'm sure you'll be able to find something similar in your country.
