Why Choose an H3 Buffer?

An H3 heavy buffer is one of the most effective upgrades for AR-15 platforms. By adding additional mass to the buffer system, it:

✔ Helps slow down bolt carrier speed

✔ Reduces recoil impulse

✔ Improves reliability with hotter ammunition

✔ Enhances overall shooting smoothness

 

This makes it especially beneficial for shorter barrel rifles, suppressed setups, and high-performance builds.

Customer video review of The Triggered Company Disruptor FRT — $279.99

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.

Customer video review of AK-47 FRT Super Safety – 100% USA Made

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.

Customer video review of Odin Works HFRT — All-In-One Buffer & Buffer Tube System for FRTs and Super Safeties

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 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!

Customer video review of Partisan Forced-Reset Drop-In Cassette Trigger (Black) FRT – AR-15 Platform (USA-Made)

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.

Customer video review of AR-15 H2.5 Carbine Buffer (5.1 Ounces)

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

Customer photo review of FDC ARC Fire V2- AS Designs FRT

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~!!!

Customer video review of AR-15 H3 Heavy Buffer 5.4oz Shake weights (V2 Reciprocating)

Fit and finish seem perfectly fine. However, I am unsure of what the purpose of this buffer actually is It is advertised as an h3 buffer with shake weights reciprocating mass which is true however it is not enough reciprocating mass to be equivalent to an h3 or H2 buffer which is unfortunately what I need to operate my system therefore as stated previously, I'm just unsure what the application of this buffer would actually be. I sent an email immediately after placing the order to either cancel the order or swap this buffer for an actual h3 and charge me the difference however that email has went unanswered. Hopefully they will approve this return and we both can move on with our lives.. Not holding my breath

Customer photo review of AR-15 H3 Heavy Buffer 5.4oz Tungsten weights (V2 Reciprocating)

This is NOT a buffer with three tungsten weights as listed in the description. This is a solid steel buffer (magnetic, weighs 4oz empty) with two smaller than normal steel weights that slide in a narrower, shorter chamber. This buffer does not work with ANY of the three main styles of FRTs. You haven’t responded to my two emails.

Pete W. 1/5 Verified

AR-15 H3 Heavy Buffer 5.4oz Tungsten weights (V2 Reciprocating)

This buffer weight does not work with my AR-15 super safety configuration. After trying several combinations, using my friend’s AR-15, swapping out uppers, lowers, buffer springs and even ammo, we were able to pinpoint the issue to the buffer weight itself. Simply swapping out my old buffer weight with the one in his rifle resulted in my super safety cycling perfectly. Due to Take Down tools’ return policy, of not being able to return “used” items, I am left $60 paper weight. Needless to say, I’m pretty unhappy about the end result here. I may just put it in a sock and turn it into a melee weapon. Who knows
