H buffer tungsten weights

[Sicilian]

Sorry if this is in the wrong section, or if it has been addressed before.

I have an AR carbine that is slightly overgassed (most come that way nowadays, because manufacturers don't bother making the gas ports smaller). I want to solve the problem with an H buffer (or maybe an H2, if needed).

So, now to the heart of this thread. I could buy an H2 buffer, and swap out the weights as needed, but then I will have an extra buffer sitting around. I am also cheap, and don't want to pay $45 bucks. So, do any Calgunners know where to buy tungsten buffer weights?

I also know that I could use tungsten powder like Spikes uses in their heavy buffers. But, the solid weights do serve a purpose, so I want to keep them in there.

Why do you think your rifle is overgassed? The size of the port is not the only thing that causes overgassed operation. Gas ports are tuned to the dwell and type of gas system to provide reliable function for all types of ammo.

Its sorta stupid to re-build a buffer when they are so cheap AND you may want to use the old buffer when the new buffer doesn't run as smooth with a certain brand of ammo.

Its like wanting to rebuild a light bulb... you are spending just as much in time, energy and money finding tungsten weights as you could just going to Brownells or Midway USA or Primary Arms, or Stag, or Riflegear or BCM or DTi and buying a H2 buffer.

OP, buy H2 buffer.
Signs of over gassed rifle you are experiencing?
Blown primers? Case rims ripped off?

An h buffer will not solve your rifle being over gassed. IF your rifle is truly overgassed to the point where is becomes an issue, the best way sans buying a new barrel is to weld and re-drill.

If you are set on building your own buffer, then it isn't that hard to do either. I believe pinewood derby has tungsten that would fit inside a buffer. Drift the roll pin out of your buffer, and the rubber cap will come out. Then you can replace the weights.

Who made your upper???

Many times, improving the spring quality (along with a heavier buffer) does a great job at dampening felt recoil.

I appreciate your frankness - *sarcasm

And, I know where I can purchase a heavy buffer. However, I enjoy building things myself

I said slightly overgassed, not dangerously overgassed

The only real sign of an overgassed system is the shell ejection. They are consistently flung to 2:00

And, it is always nice to soften the recoil from a carbine.

DPMS Oracle, which has a carbine gas system.

I am very frank and thats just me. I am not saying building is stupid, I am saying trying to build something to FIX a PROBLEM that is already available is.

I need light in my room.
1) Spend hours, lots of money and effort to build a light bulb.
2) Buy a light bulb.

Ammo "A" ejects to the 2 O'Clock position. That doesn't mean its overgassed. The chart you are referring to is one of many tools used to troubleshoot a problem. I think you know this.

If you want to tune your buffer for a certain ammo, try BBs and other things like washers. I have done this by stacking washers, fixing them together, filling the void inside with BBs that were inside a plastic tube. The total weight was 4.7oz. This was before the H2 came out. The buffer worked good until I swapped ammo. Then the carbine was unreliable.

Good luck.

Spend $1000 to $1500 on a rifle, but doesn't want to spend an extra $100 bucks to get a couple more buffers?

If you really want to roll your own, start by taking apart your buffer, shake out the weights, measure their length and diameter and then google a company near you that sells tungsten rod stock in that diameter.

Here is the best info on AR buffer et. al. http://www.heavybuffers.com/index.html

DPMS AR's are very over gassed. So I would look at the H2 or H3 buffer.

I had a 16" carbine that was over gassed as well. I would fire about 40 rounds and the receiver would be filthy with soot. It was really bad. I put a 9mm buffer in it and it was night and day. It's one of my cleanest running rifles now. The 9mm buffer delays the bolt enough to allow the bullet to exit the barrel before the breach begins to open. AR rifles are not designed to have so much barrel past the gas port, so the 16" barrel carbine has this particular problem.

I suggest a Spikes ST-T2 buffer. It's between the H and H1 weight and makes the recoil feel much nicer. $29 shipped. I have no experience "building" buffers so I can't comment on that. Cheers!

Not quite. I wish, but not quite.



Thanks for the input, guys.

I think some have read this post and think that I want to build my own tungsten weights. This is not the case. I do not want to machine tungsten stock into buffer weights. I'm not trying to build my own light bulb. I just figured with all of the H buffers out there someone would be selling the tungsten weights for them. That is all that I need. Weights only. In the past I have switched around H3 buffer weights to help tune rifles for friends.

With all of the AR stuff on the market, I figured the OEM making the weights would sell them somewhere. It is an easy install too! Just one roll pin to take apart a buffer. Oh well. I just like to save money. But, it looks like I'll buy an H3 buffer.
