PRE-ORDER 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.   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 so the parts better mate to 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 prior to 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.   Shipping & Checkout Due to a high volume of orders I’m shipping as fast as possible.
