Why Gen 3 Is the Better Kabuto FRT
Monolithic dual-tab reset architecture — Every standard Kabuto FRT resets through a single lever. The Gen 3 replaces that with a monolithic body carrying two reset tabs, spreading the reset load across two contact points. Less stress per surface means more consistent cycling and a longer service life under hard use.
CPA6 carbon fiber blend housing — Not standard nylon. CPA6 is carbon-fiber-reinforced PA6 — the same class of material used in high-stress industrial and aerospace applications. Stiffer, more impact-resistant, and dimensionally stable under heat. The Gen 3 housing handles the repeated impact loads of forced reset cycling better than any other Kabuto housing at this price.
Steel internals throughout — The lever arms, pivot pin, and critical contact surfaces are steel. The housing takes the hits, the steel does the work.
True 3-position operation — Safe, Semi-Auto, and Forced Reset. The selector functions as a standard safety even with the Kabuto device removed — no disassembly required to run semi-only mode.
USA made at an honest price — $139.99 for a Texas-made Kabuto FRT with a premium housing and dual-tab reset. No other USA-made forced reset trigger comes close at this price point.
Gen 2 vs Gen 3 — What Actually Changed
Gen 2 — $119.99
Single-lever reset architecture. Carbon fiber nylon housing. Proven Kabuto FRT design. Solid entry-level forced reset trigger — the right choice if budget is the priority.
Gen 3 — $139.99 — Recommended
Monolithic dual-tab reset. CPA6 carbon fiber blend housing. Upgraded reset architecture distributes load across two contact points for better durability and more consistent cycling. Twenty dollars more. Worth it.
Lower receiver: AR-15 pocket-cut lowers only. Not compatible with CMMG .22 lowers or AR-9 lowers. Do not attempt.
BCG: Full-auto spec (M16-profile) BCG required. The Kabuto FRT will not function with a semi-spec BCG. Any full-auto spec carrier works.
Buffer: Minimum H2 buffer required — H3 recommended. A heavier buffer prevents bolt bounce and keeps the forced reset cycle clean. Browse compatible AR-15 buffers here.
Ammo: Full-power loads only. Underpowered ammunition will not cycle the carrier far enough to engage the forced reset mechanism.
Break-in period: Dry fire 10-20 cycles before live fire. If the FRT position is not cycling cleanly out of the box, shoot 1-2 magazines in semi-auto first — this is normal on all Kabuto-style FRTs and not a defect.
Forced reset triggers are federally legal following the May 2025 DOJ settlement. State restrictions apply — verify legality in your state before purchasing. See our complete FRT legality guide for a state-by-state breakdown. ARTakedownTool.com does not ship to states where FRTs are prohibited.
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.

Thanks again for your wonderful review and for being a part of The Takedown Tools family. We hope to see you back for your next upgrade!
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.
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.
Had some initial issues with the trigger but customer service was easy to get ahold of and took care of me. Shipping was super fast, and everything is working as intended now. I wouldn’t think twice about ordering from them again.

Hey Joel,
This is GREAT to hear, and glad it was super easy
The FRT dropped right in and ran wonderfully! It cycled 22 rounds in roughly 2 seconds.
My son's first experience firing anything like this and he absolutely loved it.
I highly recommend this product for your TX22.
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.
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!

Straight drop in, no modifications. Ran great no issues yet
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.
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.
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~!!!
This enhanced semi-auto trigger is amazing the install was easy the function is great the only thing would be you need a t10 tool of your own to hold the other side. But overall 10/10 this mad my cheap Anderson ar turn heads!!!
I have yet to actually install the trigger, but mine arrived damaged from shipping. I contacted customer service and explained what happened and sent a picture of the damage. They sent me an upgraded model of the same frt, no questions asked and not a bit of hassle... Customer service and follow up is awesome.. I will definitely be using these guys more in the future
