Kabuto FRT Package · Geissele SSA Ready · USA Made

World's First — Never Sold Before Limited First Run Kabuto + SSA Insert Metal Ambi Selector USA Made

This part has never existed before. Anywhere. Nobody has ever made an insert that lets a Geissele SSA run under a Kabuto FRT — until now. We designed it, we had it machined, and the entire first run is 50 units. The Geissele-Ready Kabuto FRT Package pairs our Kabuto FRT with metal ambi selector and this first-of-its-kind Geissele SSA insert in one matched set — so the Super Semi-Automatic that's been the gold standard for combat and duty shooting for two decades finally runs under a forced reset trigger with full operational smoothness and integrity. Your Geissele stays in the rifle. Your Kabuto runs like a dream on top of it. And you're one of the first 50 people on earth to run this setup.

Geissele trigger NOT included. This package is for shooters who already own a Geissele SSA — you get the complete Kabuto FRT kit plus the SSA insert that mates them. Running mil-spec? The standard Kabuto is all you need. Running a LaRue MBT? The LaRue Cut Kabuto is machined for you.

What's In The Package

Kabuto FRT — Metal Ambi Kit

The complete kit: drop-in FRT, stainless steel 3-position ambi selector, bearing steel main pin, 3M spacer shim, sticker pack.

Geissele SSA Insert

Custom-machined piece, purpose-cut for the SSA frame. Slides in with the Kabuto during your normal install.

The Result

Consistent engagement between Kabuto and SSA — smooth reset in FRT mode, the SSA's legendary 4.5 lb two-stage break in Semi.

First Run: 50 Units

This insert has never been sold before — by anyone. When the first 50 are gone, they're gone until the next machining run.

Precision Below, Speed Above

Nobody pulls a Geissele out of a rifle to run a reset device — the SSA is the trigger generations of duty rifles were built around. Until now, SSA owners had exactly one option: leave the Geissele in the safe. We thought that was stupid, so we designed the part that ends the choice: the insert mates the Kabuto to the SSA's frame geometry, the Kabuto handles the forced reset, and in Semi your trigger is still every bit the Geissele you paid for. The only Kabuto configuration ever purpose-built for the SSA — because we're the ones who built it.

Compatibility & Required Hardware

Built for	Geissele Super Semi-Automatic (SSA) two-stage — trigger not included

Other Geissele models	Insert is machined for the SSA — running an SSA-E, SD-E, or other model? Ask us before ordering.

Frequently Asked Questions

Is a Geissele trigger included in this package?

No — this package is for shooters who already own a Geissele SSA. You receive the complete Kabuto FRT metal ambi kit plus the custom SSA insert that pairs them. The SSA itself comes from Geissele or your favorite dealer.

Has anyone made this before?

No — this insert is a first. It was designed by us, machined for us, and this listing is the first time it has ever been offered for sale by anyone. The first production run is 50 units.

I already own a Kabuto — can I just get the insert?

Yes — the Geissele SSA insert is available on its own for $29.99 and drops into your existing Kabuto setup.

Does it work with the SSA-E or other Geissele triggers?

The insert is machined for the SSA specifically. Other Geissele models share family geometry but aren't what it was cut for — contact us before ordering and we'll tell you straight.

What else do I need to run it?

The standard Kabuto hardware rules: an M16-profile BCG and an H2 or H3 non-solid buffer. Our Trigger Supply M16 BCG and buffer collection cover both.

Is this legal?

Forced reset triggers are semi-automatic — one round per function of the trigger — and legal in most states with restrictions in some. Check Are FRT Triggers Legal? before ordering.
