Every forced reset trigger build on an AR-15 requires three things done right: the trigger, the BCG, and the buffer. Get any one of them wrong and your forced reset trigger won't run reliably — regardless of how good the trigger itself is. This bundle eliminates that problem entirely.
The Partisan Disruptor FRT, the Boron M16-cut BCG, and the Armaspec Sound Mitigation Buffer Gen3 H2 — all three components, all 100% USA made, engineered to work together as a complete system. The premier forced reset trigger upgrade kit for any AR-15 platform, at the best combined value available.
Why these three components together? The Partisan Disruptor forced reset trigger requires an M16-profile BCG and a minimum H2 buffer to cycle reliably. Most FRT failures are caused by running the wrong BCG or the wrong buffer — not a defective trigger. This bundle eliminates both variables from day one. Everything correct, everything USA made, everything ships together.
The Partisan Disruptor is The Triggered Company's patented drop-in forced reset trigger for AR-15 mil-spec platforms. It installs without modification to your lower receiver and delivers the rapid, controlled cycling that forced reset triggers are known for. 3.75–4.1 lb pull weight. Compatible with 5.56, 300 BLK, and 9mm DI platforms.
The Disruptor is the most proven forced reset trigger in the lineup — in stock, battle tested, and the starting point for any serious AR-15 FRT build. This bundle pairs it with the two components it requires to run correctly from round one.
The BCG — M16 Cut
A forced reset trigger requires an M16-profile BCG — no exceptions. The M16 carrier tail provides the extended geometry that engages the Disruptor's reset lobe on every cycling stroke. A standard semi-auto carrier profile will not provide consistent reset regardless of buffer weight or ammo selection.
The MPI Nickel Boron BCG is the correct M16-cut carrier built to MIL-SPEC standards throughout — Carpenter 158 bolt, 9310 carrier, magnetic particle inspected, hard chrome firing pin, MIL-SPEC gas rings and O-ring. The nickel boron finish runs cleaner, runs harder, and cleans faster than standard phosphate — an advantage that compounds on every forced reset trigger build where the BCG cycles at higher rates.
The Armaspec SMB Gen3 H2 — Silent Captured Buffer
The Armaspec Sound Mitigation Buffer Gen3 H2 meets the H2 minimum threshold (4.7 oz equivalent) required for reliable forced reset trigger function. Unlike a standard heavy buffer, the SMB Gen3 is a captured system — the buffer, spring, and polymer guide rod drop in as a single unit. The spring rides on the guide rod rather than against the buffer tube wall, eliminating spring noise and reducing heat and friction on every cycling stroke.
Adjustable spring tension. Lifetime warranty. 100% USA made. At $59.99 it is the best value heavy buffer available for any forced reset trigger build — and this bundle includes it alongside the trigger and BCG it was designed to complement.
Running a suppressed build or sub-16" barrel? Consider the H3 version of this bundle ($469) — the heavier 5.6 oz equivalent weight gives you more cycle control margin for faster-cycling suppressed or short-gas configurations.
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. No offshore sourcing. No compromised materials. The premier all-American forced reset trigger upgrade kit — built by Americans for Americans who demand the 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.

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!!!
