I just got back from the range from using my new Tromix H3 Buffer.  

I have to admit I was a little skeptical about this working as well as my TRUE H3 buffers with three reciprocating tungsten weights.  (I took my H3 with me, just in case I needed it...)  

However, I didn't need to swap my buffer back to the H3!  The Tromix worked perfectly for me!  

Before I got it in hand, I was having a little trouble understanding how this buffer works.  Makes sense now, and the reciprocating weight doesn't matter what it is made of - steel or tungsten, the dead-blow principle is the same.  

If you are hesitant to try a Tromix buffer like I was, don't be.  It just works.  I'm gonna have to get more of these!

Edited to add - I only put 200 rounds downrange with this today.  I'll shoot it more in the near future, and if I have any issues, I'll update here.

Tony makes good stuff. Should be releasing a 9mm buffer soon.

He started making the A5-H2 weighted buffers simply because I asked.
He's a good dude.
My rate of fire was inconsistent and his buffer and a tubbs flat spring fixed it.

Do want.
I wanted a mission, and for my sins, they gave me one.

It's released. I have mine in hand, just haven't tested it yet.
It was not preached to the crowd,
It was not taught by the State.

This is pretty new to the market, so probably not all that many have been tested.  https://tromix.com/product/ar-15-9mm-buffer-4/

Based on my experience with a Tromix H3, I'd say the 9mm version might well be just exactly what you need!  

Buy one and try it, and come back here to report your experience with it.  That's how we all learn!

I ordered 2 of the Tromix H3 buffers when I ordered 2 Trigger Kickers. Installed it all in 2 5.56 SBRs and they work great.
I hated going to weddings. All the grandmas would poke me and say "You're next". They stopped that when I started doing it to them at funerals.

Yep. I put a tromix h3 and a $0.15 3d printed kabuto into one of my ARs and it ran great immediately.

My Tromix H3 buffer solved a long standing issue of only getting one shot that I was having with a FRT.   The FRT would not work with tungsten weights in an H1 and another brand H3 with no sliding weights.   I am very pleased with mine.

Look forward to receiving them.

Had issues with a AR9 running smoothly with a V1 arc fire.

The tromix 9mm dead blow buffer worked great.  
8" barrel
Gibbz side charging upper
Huxwrx Ca$h 9k suppressor.
Nice chug, chug, chug speed too.
Thats with 3.7g VV N320 and 147g round nose.

I have two of his H3 sliding buffers. They are the Cats meow. Had an Atrius FRS that was irritable but now runs smooth, a Partisan Disrupter that wasn’t  having it with standard carbine buffer but is rocking and rolling now.

I wonder if his 308 buffer will work with a Q gun or Maxim with cqb stocks.

I have to use the 7.65 oz Maxim 9mm buffer to get my shorty Q clone 556 guns to run.  They rip with it.  It’s the same length as Tony’s 762 buffer.

@tonyrumore
Your standard 308 buffer is on clearance but you say not to run it with frt.  Has it been tried with the above stocks?  I hate to drop 80 on that fancy Lima6 buffer if the 20 dollar clearance one will work.

Our standard 2.5" AR-10 carbine buffer ($20) only has 2.7oz of sliding weight, which is not usually enough to stop bolt bounce.  All testing with the 2.5" buffers was done in a Lima 6 and we found that it needed around ~3.9oz of sliding weight to run.  The 2.5" Lima 6 buffer uses Tungsten weights inside of sliding steel body, for a total sliding weight of 4.8oz.

And of course, since it uses Tungsten, it's expensive.

Awesome thanks for the clarification.  I’m gonna order one of each.  It’s only 20 bucks but I can use it in the AR10 based 8.6 if it doesn’t run.

I’ll be sure to let you know.

Just purchased my first one, going to try it in an SBR with an AZR 3 position. Thank you all for the recommendations.

I have a Tromix H2 I’m going to try in my 10.5” LWRC. That fucker runs over 1,000 rpm with a carbine spring, carbine buffer, and FireTeam556.

Success yesterday w/ Tromix H2 and H3 with standard carbine spring ARC V1 equipped lower with an overgassed 11" 5.56 upper and my old SDN6 on it.  I did not try without the can but it ran like a top on Federal M855 and was indistinguishable from my regular H2 and H3 buffers.  

To the Tromix guy, these are great and I hope you make a fortune off of them during the FRT boom.

I previously posted this in the Trigger Kicker thread -


+2 on the Tromix H3 buffer for the Trigger Kicker, Super Safety and ARC FIRE V2.

I ordered 2 Tromix buffers- all ran right out of the box perfectly with all the above FRT’s- Anderson & Spikes lowers, short bbls, 16”, 20”, suppressed and unsuppressed.  ALL of them 😁

NO issues at all.

Tony was excellent on communication and advice. 5 stars across the board.

I also have other H3 buffers with sliding weights from PWS, and 2 other mfgs- all ran well.  

The only one I have that hasn’t worked yet is Odin Works heavy FRT buffer.  Hasn’t worked on any of my FRT’s yet.  No idea why.  Dead trigger and light strikes abound.

Fooling around with springs now, haven’t found the right recipe yet.   LMK if anyone has advice/insight.

For $39 each, I’m going to stick with Tromix buffers for now and advising my friends to do the same as they get started.

Tony- you’re the man!
