CNC Machined Housing · CNC Metal Selector · Single-Sided or Ambi · Zero Printed Parts
This is the CNC Kabuto FRT, the highest-grade Kabuto we have ever carried. The housing is CNC machined from 6061 aluminum and anodized red. The lever, activator and pin are CNC and EDM cut from S136 steel, then hardened and blackened. And for the first time on any Kabuto we sell, the selector is CNC machined metal too. No printed housing. No printed selector. Nothing in the fire control path that can snap or soften.
Build it your way: run the one-piece single-sided CNC selector, or step up to the ambidextrous 3-position CNC selector in black, red, blue or gold.

Single-Sided CNC (Black)One-piece machined metal selector. Clean, low-profile and built to take real torque.
Ambi CNC: Black, Red, Blue or GoldFully ambidextrous 3-position control from both sides of the receiver, with stepped levers for a positive grip. Match the red housing or make it pop.

Fitment: Read Before You Install
The Kabuto works off the top of your lower receiver, so the distance to the safety and trigger is different on every lower. That's why no single activator length fits every rifle. The housing is pre-trimmed to fit as many lowers and uppers as possible, but tolerances vary from manufacturer to manufacturer, so some rifles will need minor shaving.
Activator length check: the bottom tip of the activator presses the trigger down to reset it. If the tip is too long, it can't travel all the way down and pushes the whole assembly up, which binds the bolt.
To test: push the lever all the way back into the reset position, then look at how the housing sits. If the housing lifts, the activator tip is too long. Shave the bottom tip a little at a time until the housing stays seated.

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!!!
