The Premier AR-15 FRT Kit — Built for Suppressed & Short-Gas Builds
Every forced reset trigger build on an AR-15 requires three things done right: the trigger, the BCG, and the buffer. The H3 version of this bundle is engineered specifically for shooters running suppressors, short-gas systems, or sub-16" barrels — where standard buffer weight isn't enough and you need maximum cycle control margin from the start.
The Partisan Disruptor FRT, the MPI Nickel Boron M16-cut BCG, and the Armaspec Sound Mitigation Buffer Gen3 H3 — all three components, all 100% USA made, all shipped together. The premier all-American forced reset trigger upgrade kit for the shooter who demands the best.
Why the H3 for suppressed and short-gas builds? Suppressors increase gas pressure through your AR-15 system, causing the BCG to cycle faster than on an unsuppressed rifle. Short-gas systems under 16" have the same effect. On a forced reset trigger, a faster-cycling BCG means the bolt returns to battery before the reset lobe can engage — causing reset failures. The H3 at 5.6 oz equivalent slows the bolt return enough to compensate, giving your forced reset trigger the timing margin it needs to run reliably on every cycle.

Not sure which to choose? Go H3. At only $10 more than the H2 bundle, the additional buffer weight gives you more margin for reliable forced reset trigger function — especially as component wear accumulates over higher round counts. The H3 is the safer long-term choice for any serious FRT build.
The Partisan Disruptor is The Triggered Company's patented drop-in forced reset trigger for AR-15 mil-spec platforms. Drop-in cassette — no modification to your lower. 3.75–4.1 lb pull. Compatible with 5.56, 300 BLK, and 9mm DI. The most proven forced reset trigger in the lineup. This bundle pairs it with the M16 BCG it requires and the H3 buffer that keeps it running reliably under the increased gas pressure of suppressed and short-gas configurations.
The MPI Nickel Boron BCG — M16 Cut
No forced reset trigger will run reliably without an M16-profile BCG. The MPI Nickel Boron BCG provides the correct M16 carrier geometry that the Disruptor's reset lobe requires — plus MIL-SPEC construction throughout. Carpenter 158 bolt. 9310 carrier. Magnetic particle inspected. Nickel boron finish that runs cleaner and cleans faster than phosphate. On a suppressed build cycling at higher rates, a BCG that resists fouling buildup is not a luxury — it is a necessity.
The Armaspec SMB Gen3 H3 — Silent Captured Buffer
The Armaspec Sound Mitigation Buffer Gen3 H3 at 5.6 oz equivalent weight is the recommended buffer for suppressed forced reset trigger builds and any AR-15 running a short-gas system under 16 inches. The captured polymer guide rod keeps the spring off the tube wall — eliminating the metallic spring rattle that gets dramatically louder under a suppressor — while the H3 mass compensates for the additional gas pressure that suppressors generate. Adjustable spring tension. Lifetime warranty. 100% USA made.
Why 100% USA Made Matters
Every component in this bundle is designed, machined, and assembled in the United States. The Partisan Disruptor FRT by The Triggered Company. The MPI BCG by MPI. The Armaspec SMB by Armaspec. The premier all-American forced reset trigger upgrade kit — built by Americans for Americans who demand the absolute best from their AR-15 platform.

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!!!
After running a few tests, I discovered I have an issue with the buffer. The rifle is jamming after 2 shots in auto. I have 2 identical partisan disruptor gets with the same bcgs and h3 buffers. All the same parts ordered through takedown tools. One setup works just fine and both triggers work correctly but one of the buffers is jamming up. Can I send it back for a replacement?
The FRT works great once I got time to get it set up. I however paid for express shipping to have it the weekend before the holiday so I could get it set up and shooting great. We had a shoot set up for the Fourth of July. It was shipped ground and didn’t get it delivered in time to set up and run through it. I sent an email asking what hold up on shipping was and never seen a response.
This FRT package is Kick Ass. Bad to the bone and very easy to install. Installed mine on a Anderson Lower, didn't work first try but when I added the H-3 buffer it worked flawlessly. Going to order another one for my 5,56 AR.
