Metal Ambi Selector · AR-15 & PCC · Dallas Texas USA · In Stock
The Kabuto FRT with metal ambi selector is the most complete Kabuto kit on the market — and the only one that ships with a full metal ambidextrous stainless steel 3-position selector as standard. This has a carbon fiber (CPA6) Nylon Housing, but Not a printed nylon selector. No afterthought upgrades. Metal selector, metal internals, USA made in Dallas, Texas, and confirmed compatible with AR-15, PCC builds, LaRue, and Guisselle triggers right out of the box.
Every other Kabuto kit ships with a 3D printed polymer selector. This one doesn't. That's the difference.

Metal Ambi Selector — Why It Matters
-
Stainless steel construction — not printed nylon, not polymer. The selector body, timing plunger, and timing lever are all metal. No printed parts in your safety selector
-
Ambidextrous out of the box — left and right hand operation with no additional hardware or modification required
-
Tighter detents — metal-to-metal engagement delivers crisper, more positive detent feel between Safe, Semi, and Forced Reset positions versus printed selectors
-
Durability under hard use — printed selectors can wear, crack, or deform under sustained use. The metal selector doesn't
-
Bearing steel main pin — the only Kabuto on the market with a bearing steel main pivot pin. Bearing steel is engineered specifically for smooth, high-load rotational movement — lower friction, higher wear resistance, and more consistent reset feel over the life of the trigger than standard steel pins
-
Upgrade most Kabuto owners pay extra for — included at no additional cost in this kit
The 3M Spacer Shim — A Problem Nobody Else Solves
Wide-wall AR-15 lowers — and many PCC lowers — have a slightly wider shelf that allows the Kabuto to shift laterally during operation. This causes inconsistent reset engagement and is one of the top Kabuto reliability complaints. The included 3M adhesive spacer shim fills that gap precisely, locking the Kabuto in position and eliminating side-to-side movement. It ships in every kit. Use it if you need it.
Platform Compatibility
AR-15 and PCC confirmed. This is one of the only Kabuto kits that runs reliably in pistol caliber carbine builds.

Not compatible with: CMMG .22 lowers, M16-cut lowers. Requires an M16-profile full-auto cut BCG — a semi-spec BCG will not engage the reset mechanism. H2 or H3 buffer strongly recommended. Avoid solid buffers.

Break-In
Before live fire, cycle and dry-fire the unit 10–20 times to smooth the contact surfaces. This is standard procedure for all Kabuto-style FRTs and takes less than five minutes. If you experience any stiffness in the reset cycle, a light polish on the lever contact surface resolves it immediately.

NSPEC Innovations Kubota Gen 2 and Gen 3 are also in stock starting at $109.99 — a proven drop-in Kabuto-style FRT for pocket-cut AR-15 lowers. Different manufacturer, different design.
Legality
Forced reset triggers require one trigger function per round fired and are semi-automatic devices. State-level restrictions apply in some jurisdictions.

Frequently Asked Questions
What makes this Kabuto different from other Kabuto triggers?
This Kabuto ships with a full metal ambidextrous stainless steel 3-position selector — not printed nylon. The metal selector delivers tighter detents, better durability under hard use, and ambi operation right out of the box. It also includes a 3M spacer shim for wide-wall lowers and die-cut stickers. Most Kabuto kits ship with a printed polymer selector and no shim.
Does this Kabuto work with PCC builds — 9mm, .40 S&W, .45 ACP?
Yes. This Kabuto is compatible with AR-15 pistol caliber carbine builds including 9mm, .40 S&W, and .45 ACP PCC platforms. It is one of the few Kabuto configurations confirmed to run reliably in PCC setups.
What is the 3M spacer shim for?
Some AR-15 lowers — particularly wide-wall variants and certain PCC lowers — have a slightly wider shelf that allows the Kabuto to shift side to side during operation. The included 3M adhesive spacer shim fills that gap, securing the Kabuto in position and eliminating side-to-side movement. It is included in every kit and is one of the most overlooked fitment solutions in the Kabuto market.
Is this compatible with LaRue and Guisselle triggers?
Yes. This Kabuto is confirmed compatible with LaRue and Guisselle triggers, along with standard mil-spec triggers. It covers more trigger compatibility than most Kabuto units on the market.
Does this require a full-auto cut BCG?
Yes. Like all Kabuto FRT and forced reset trigger systems, this unit requires an M16-profile full-auto cut BCG. A semi-spec BCG will not engage the reset mechanism. See our
USA Made M16 Full Auto Cut BCG if you need one.
What buffer weight is recommended?
An H2 or H3 buffer is strongly recommended. Avoid solid buffers — they do not provide the correct dwell time for the forced reset mechanism to engage reliably. See our
AR-15 buffer collection for compatible options.
Is the Kabuto FRT legal?
Forced reset triggers require one trigger function per round fired and are semi-automatic devices. State-level restrictions apply in some jurisdictions. Review the full current breakdown at
