NOT NOVRITSCH SSQ-22 Compatible!!
Due to the different shape of the trigger guard and grip angle of the SSQ-22, none of our existing underlever conversion kits will fit the new gun. We intend to eventually produce a lever-action kit to suit the SSQ-22 if there is sufficient demand from the community.
NEXT 3-MONTH BATCH CUT-OFF - 1st May 2023. Estimated dispatch end of June 2023.
Underlevers will now be produced in 3-month rolling small batches, made-to-order, with increased prices to account for much smaller batches, but with accelerated delivery schedules.
Please only order the underlever, any additional items on your pre-order will be removed as we do not wish to hold stock indefinitely.
This Underlever Bolt-Action conversion kit has been specifically designed to be compatible with this exact stock - Boyds 3Z2681W1B1ZZ
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.
We have been made aware there is some variation in the fit & finish of the wooden grip from Boyds with this stock which may cause minor fitment issues for the BRT underlever. You may have to perform some additional sanding/filing/spacing to position your receiver correctly in the stock for the lever to sit flush with the grip.
It is not compatible with the Boyds At-One stock or any other similar Boyds stock. They all have different grip profiles so will not suit this lever.
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 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)).

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.
