Specs of The AR-TT
Overview
The Armaspec Sound Mitigation Buffer™ Gen3 (SMB™) H3 is a single-stage captured drop-in replacement for your standard AR-15 buffer and spring. Silent operation. Adjustable spring tension. H3 weight — the recommended threshold for forced reset trigger builds, suppressed AR-15s, and short-gas platforms. Lifetime warranty. 100% USA made. $59.99.
If you're running a forced reset trigger or Super Safety on a suppressed rifle, a short-gas or sub-16" build, or any platform that demands maximum cycle control — the H3 SMB Gen3 is the buffer. More mass than the H2 minimum, silent captured operation, and fully adjustable spring tension at the same $59.99 price point.
FRT & Super Safety Recommended: The SMB Gen3 H3 at 5.6 oz equivalent weight exceeds both the H2 minimum and the H3 recommended threshold for reliable forced reset trigger and Super Safety operation on AR-15 platforms. It is especially recommended for suppressed builds, short-gas systems, and any forced reset trigger build where maximum cycle control is required. Works with the Partisan Disruptor FRT, AS Designs ARC-Fire V2, Hoffman Tactical Super Safety, and any other drop-in forced reset system on a standard AR-15 platform.

H2 vs H3 — Which SMB Do You Need?
| SMB Gen3 H2 | SMB Gen3 H3 (This Product) | |
|---|---|---|
| Equivalent Weight | 4.7 oz | 5.6 oz |
| FRT Threshold | Minimum viable | Recommended |
| Suppressed Builds | Marginal | Yes — recommended |
| Short Gas / Sub-16" | May need tuning | Recommended |
| Standard Carbine 16" | Works well | Works well — more margin |
| Price | $59.99 | $59.99 |
Not sure which to choose? Go H3. At the same price, more buffer weight gives you more margin for reliable forced reset trigger function — especially as your round count climbs and component wear starts to affect timing. The H3 is the safer long-term choice for any FRT or Super Safety build.
Why Silent Matters on a Forced Reset Trigger Build
A standard buffer spring scrapes against the inner wall of the buffer tube every time the BCG cycles. On a forced reset trigger or Super Safety build — where cycling rates are significantly higher than standard semi-auto fire — that friction compounds. More cycles per second means more heat, more noise, and faster spring fatigue.
The SMB Gen3 eliminates spring-to-tube contact entirely. The polymer guide rod centers the spring throughout the cycling stroke, front and back, keeping metal off metal. The result is quieter operation, less heat in the tube, and a spring that maintains consistent tension through higher round counts — which means more consistent timing for your forced reset trigger reset cycle.
At $59.99 with a lifetime warranty, the H3 SMB Gen3 is the best value heavy buffer available for any forced reset trigger or Super Safety build on an AR-15 platform.
Installation
- Insert polymer base with guide rod into the buffer tube
- Insert the spring onto the guide rod
- Insert the buffer over the spring
No tools required. Drop-in replacement for any standard AR-15 carbine buffer tube setup.

Overall rating: 4.4 / 5 from 1717 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.

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

Armaspec SMB Gen3 H3 Sound Mitigation Buffer — Silent Captured AR-15 Buffer
This is my girlfriend shooting the AR with the H3 buffer and Partisan disruptor Frt. Works perfect. Thank u the take down tool team.
Armaspec SMB Gen3 H3 Sound Mitigation Buffer — Silent Captured AR-15 Buffer
I recently installed an FRT in a lower I use for multiple uppers of different caliber. I couldn't get it to operate properly, and after a little research I discovered I needed an H3 buffer. Since I already had a captured system in the lower I wanted to stick to that design. I found an H3 captured buffer system for a great price on your website and ordered it. Simply replaced the old buffer, drove to the range, and opened fire. The video shows firing the 3rd mag. The barrel heat was the only reason I stopped. Great buffer system.

Armaspec SMB Gen3 H3 Sound Mitigation Buffer — Silent Captured AR-15 Buffer
It isn't that the buffer doesn't function, I have not been able to get the BCG and the buffer to function together. When placed in the same AR they do not seem to allow the trigger to function. Placed in separate ARs and they function fine.
