This Underlever Bolt-Action conversion kit has been specifically designed to be compatible with the Hogue OverMolded rubber .920" bull barrel 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.
Package DISCOUNT CODES below!
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.
If you also want to retain semi-auto operation for your standard bolt carrier to hot-swap with, we recommend purchasing an SSB and a Genesis kit with your Underlever, or an SSB and spare KC-VSR nozzle to convert your existing bolt assembly to VSR type. 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)).
DISCOUNT CODES to use at checkout if purchasing an Underlever with a combination of the parts listed in your basket:
- "LEVER1" = Underlever + Genesis Hop unit parts = £200 (£25 discount)
- "LEVER2" = Underlever + SSB = £210 (£15 discount)
- "LEVER3" = Underlever + Full Genesis kit = £250 (£30 discount)
"LEVER4" = Underlever + Gen Kit Parts + SSB = £255 (£35 discount)
- "LEVER5" = Underlever + Full Genesis kit + SSB = £300 (£45 discount)
Hint: If ordering more than 1 Underlever, try adding a 2 e.g. "LEVER42"
If you have already purchased some of these parts recently (AFTER JANUARY 1ST 2021) and wish to now purchase an Underlever in addition, then we can still offer you the discounts above. Please place your order as normal, then send us a message on Facebook, quoting your #1234 order number, and we will check your recent purchase history and issue the appropriate package deal discount as a refund. Orders placed before 1st January 2021 will not be eligible for back-dated package discounts.
THIS IS A PRE-ORDER WITH NO EXACT DELIVERY DATE, LIKE A KICKSTARTER. The factory order to manufacture this batch of underlevers will only be placed once we have reached 20 pre-orders. You can see how close we are to that goal in the product title above. The count is manually updated so do not be alarmed if it doesn't change when you place your order.
If the required number of orders is not reached within a reasonable timeframe (eg. 3 months from launch), then unfortunately the pre-order will be cancelled and all orders refunded. If we successfully exceed the minimum required 20 pre-orders, then we will announce a suitable cut-off date to end the pre-orders for this batch of underlevers. If you miss that date, you will have to wait until the next pre-order of underlevers opens a few months later.
If you have any questions about the terms stated above, then please contact us by Facebook message at https://www.facebook.com/RogueWorx

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
The kit will be produced in 7075 aluminium, and is available in our usual range of anodised colours and patterns. If we have spare stock of hop wheels available, and your order includes a Genesis hop wheel, we will also anodise the hop wheel to match your underlever kit. Otherwise you will receive a standard black hop wheel.
The Underlever itself is compatible with the standard bolt carrier and hop unit, as long as you disable the blowback on your standard bolt carrier. Achieving this is a complicated task in itself, which is why we also created the Solid-State Bolt.
The Solid-State Bolt provides a drop-in sniper bolt-action function and incorporates a VSR-type nozzle, so is only compatible with the Genesis hop unit which uses VSR hop rubbers. The SSB can easily be swapped back for a normal semi-auto bolt assembly if you want to remove the underlever and go back to semi-auto in a few minutes.
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 shit, so buy one of these kind of tools to avoid that cosmetic damage:
or something cheaper like this:
I'm sure you'll be able to find something similar in your country.
