Assembled Kabuto Drop-In (Edited Version)
Kit includes
• 3D Printed Carbon Fiber Nylon Three Position Selector
• Assembled Steel Internal Activator and Lever with a 3D Printed Carbon Fiber Nylon Housing
Compatibility
This drop-in is designed only for the AR-15 platform — it will not work in a CMMG .22 or an AR-9, as those use different levers. Mil-spec triggers are the only triggers fully confirmed for compatibility at this time; your mil-spec trigger does not require modification and will work as-is once the unit is fitted correctly. Other trigger types may work but are untested.
The system has been successfully fitted to many popular AR-15 builds, including PSA, Aero Precision, Anderson, Daniel Defense, Core15, and DPMS. While these brands have been tested and do work, we cannot guarantee fitment in every rifle platform.
These require an M16 bolt carrier groups, and an H3 non-solid buffer weight to function as intended.
Installation & Fitment Notes
On the assembled version, there are two prongs on the drop-in that push both sides of the trigger to cause it to reset. If the part won’t fully seat during installation, the smaller prong on the right is usually contacting the disconnector. Gently bend that leg outward a small amount with pliers so it clears the disconnector, and the rifle will close. This feature is intentional — the design prevents the unit from being modified or functioning like a DIAS.
Break-in & Finish
These are raw parts. Normally, cycling and dry-firing the unit 10–20 times in both modes helps wear off any rough edges, allowing the parts to better mate with your rifle’s tolerances. If you prefer not to cycle/dry-fire, the bottom of the lever may require light polishing. Each lever is tumbled in a deburring/polishing media before shipping.
Buffer Requirement
A heavier buffer weight (H2–H3) is required — do not use a solid buffer.
Safety / Use
Remember: this is an FRT. Do not hold the trigger down like a full-auto — doing so will cause premature wear and may ruin the drop-in.

Kabuto
I've shot a few hundred rounds out of 2 of my ars I have them in, and so far its been freaking awesome! A little shaving and polishing, and already had good m16 bcgs and h2 and h3 buffer, and man they run great! A little fast, but fun as hell!! And so far no hiccups and doing great! I'd say best bang for the buck on the market today!!! If I get more ars id def buy more of these kabutos

My Kabuto spits pure hatred!!!
FUCKING EXCELLENCE! I finally got to try out my Kabuto in my 10.5 PSA and she worked flawlessly. I was able to hit three round bursts and had the range officer and manager talk a little shit to me, low key threatening to call the police on me. One of those "Thread on everybody but ME" types. Anyways, excellent work Sir.
