About the Builders Kit
The Builders Kit is a complete do-it-yourself package — everything you need to build your own Drop-In Kabuto is included. All components are identical to those used in the assembled version. We strongly recommend watching the step-by-step builders tutorial on our Facebook page before buying to make sure the kit is right for you.
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.
Assembly & Fitment Notes
The assembled unit (what you will build from the kit) contains 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 medium 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
Please allow 1-3 days for shipping. Also, please double-check your shipping information before checkout!

Frt Build kit
Pretty self explanatory other than the part where you need to hammer the pins down to make sure it's nice and tight. Haven't shot it yet but installing was pretty straightforward.

FRT build kit (unassembled)
Assembled kit without any real hiccups,. With my Anderson lower I did have to grind down 5mm pin to fit flush,. Other than that ,went together, just like vid link. My ar came with m16 (BCG) so only thing had to swap out was buffer to h2,. So far so good,. I plan to upgrade to metal housing next ,. The 3d print works but I prefer metal for the long haul,. Lil pricey at moment,. Buffers are dam near impossible to find in stock,. I wanted an adjustable type , ended up with kak h2 5.3 oz. Their h3. Was 6.4oz. With 16 in barrel runnin un suppressed work fine with h2 . First tried with stock buffer and would not cycle,. So lil tweaks here and there,. I’m rambling due to being very satisfied with super safe solutions shipping quick also,. So thanks everyone at Super Safe . I’ll be able to protect my lil fam when shtf.. ?

Kabuto Drop-In FRT (Builders Kit)
I have been extremely happy with my entire purchasing experience with Super Safe Solutions. The product was easy to assemble with youtube provided instructions. The results with my PSA lower far exceeded my expectations. Repeat customer. Sharing my experience with friends and family. The drop-in is a must have. The price point is incredible. I always wanted an FRT, but not at Rare Greed’s prices. Great job Alabama!

Smooth running
Ran in a 16" 556. No delays, no hangups and just a smooth run. Well worth trying it out if you are on the fence about an FRT. Able to be removed and replaced without taking the weapon apart is a plus.
