Specs of The AR-TT
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. No 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.
What's In The Box
Kabuto FRT
Full functioning forced reset trigger — drop-in, no permanent modifications required
Metal Ambi Selector
Stainless steel 3-position ambidextrous safety selector — Safe, Semi, Forced Reset
3M Spacer Shim
Adhesive shim for wide-wall lowers — eliminates side-to-side movement in variant AR-15 and PCC lowers
Die-Cut Stickers
Kabuto branded die-cut sticker pack included with every kit
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.
AR-15 Mil-Spec
PCC 9mm
PCC .40 S&W
PCC .45 ACP
LaRue Triggers
Guisselle Triggers
Mil-Spec Triggers
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.

Legality

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 Are FRT Triggers Legal? before ordering.

Customer Reviews
Overall rating: 4.4 / 5 from 1798 reviews.
I ordered this thinking I would beat the next stupid ban. So the trigger arrived very fast, just a few days, and I didn't pay for the extra shipping charge for getting it faster. Wasn't needed in my case. This was so easy to install a blind person could do it. Then I took it to the range and I expected it not to work like it was described. OMG did my face light up! Burned up two magazines in less than 10 seconds I think. And is still safe, and it retains the semi auto, or one shot per pull capability. I'm buying more for my other AR's now.
Second one i bought now and still flawless operation. Would recommend this product to anyone who likes to go through ammo.

It wasn't exactly what I was expecting but I gave it a try. The installation video sucks because I couldn't see what he was doing but I ended up getting it. You have to learn how to run it as there's a little bit of a trick to it but once you do that it's fun to use.
Easy install, no problems.
Partisan Disruptor FRT (Black) + M16 BCG + H3 Buffer Bundle — AR-15 (USA Made)
This thing is more fun than a bucket of puppies
First time using the Disruptor drop-in trigger I couldn't get it to work, even after swapping in an H2 buffer. This H3 heavy-duty spring combo finally did the trick. Rifle is an older S&W Sport II. Suppressor is SilencerCo Velos 556. Very happy with the result and looking forward to adding Disruptor FRT and this buffer/spring to at least two more rifles.

Store owner replied: Glad you loved it! Suppressed can be a fickle one too at times
Super easily installation. Works flawlessly, not one hiccup out of the few hundred rounds I’ve gone through so far.
Awesome and easy to install! I have a PSA 300blk and didn’t even need to change buffer weight to make it run great.

Safe, Semi, FRT. Until you experience it, you just don’t know what it’s like. But once you do know, you’ll want more. An addiction that is backed by the Constitution. 2A for LIFE.
Works perfect
Worked amazingly. Was everything I hoped it would be. Would definitely recommend these guys to anyone looking to purchase firearms accessories. Had a couple small order issues in the past and they were handled very quickly and expertly. As a result I try to give them as much of my business as possible.
Super easy to install, runs smooth and without failure in a completely stock $500 American tactical AR, there are plenty of videos showing how to install it. Would and am buying this trigger kit again, and pairing it with a lighter spring kit, there isn’t any weird quirks with it, I simply installed it with some oil and my factory pins and springs and it worked without polishing or any other modifications. Super happy with it!

All the literature online made it extremely easy to install. In my opinion this is the best one.
Partisan Disruptor FRT Trigger for AR-15 – Drop-In System (USA Made)
Store owner replied: Hey GLAD YOU LOVE IT!
Functioned fantastically. I absolutely recommend a heavier buffer. I have a Ruger AR lower and it fit perfectly. Really really enjoys the metal mags. Had loading issues, disappeared when I swapped to metal mags. Selector switch works slightly better than original. I used a extra spring I had laying around and got an H3 buffer. Make sure you have the full auto BCG or this product will not function.
Partisan Forced-Reset Drop-In Cassette Trigger (Black) FRT – AR-15 Platform (USA-Made)
I ended up needing something slightly lighter to run the G Lever FRS, but the H2.5 is probably a good option for a suppressed build with more back pressure
Had to do a minor tweak to tappet wire but other than that it was a drop in kit. Seems to be made of quality steel. We all are now having great fun with it.
Trigger worked perfect. Only thing I had to do was get a h3 buffer (heavy) tube and it was flawless. Dumped 2 mags in a matter of seconds.
Works flawless when you have a h3 buffer and im going to buy 5 more 😆 🤣

Odin Works HFRT — All-In-One Buffer & Buffer Tube System for FRTs and Super Safeties
My first ARC-Fire ran like a champ! I never had a hiccup or problem, and everyone on the range stared like I was a criminal...🤣 It was the V1, and man I was happy. Then all of a sudden... I watched a video that showcased the ARC-Fire V2, with a 0-45°-90° ambi selector, and I had to have one. After all, it was going in my HK MR556 A4, and it has the markings on the lower for a 0°-45° selector, and I, of course, wanted it to match. So I bought one... While visiting AS Designs website, I noticed they sold HK style selector levers for their ARC-Fire V2. So I bought some... You CANNOT go wrong with this company! Their products are, in my and many others opinion, the best FRT on the market today! Just go to YouTube and pull up a 'Juicy Media' video, and he demonstrates a bunch of different brands of FRT and explains the pros/cons of the others, and explains why he prefers AS Designs! 5 MF'ing ☆'s~!!!
Works great with a h3 buffer, didn’t jam once
Simple to install, and fun to shoot
