Most Helpful Positive Review buffer weight review
it works as advertised and creates an H2 buffer for AR rifles that utilize the new Geissele 42 AR buffer. I should note that it will only work with the super 42 buffer do to its smaller diameter and will not work in a standard buffer setup.
Most Helpful Negative Review Geissele Tungsten Weights
Geissele makes high quality firearms and accessories. They unfortunately tend to be overpriced and proprietary. The Super 42 buffer and buffer springs are a perfect example. Due to inner diameter of buffer spring you can only use a Geissele buffer. That’s why they are only sold as a set. You have th...

Perfect way to tune your AR

by Collin Eads, Verified Owner from NC, United States Written on August 2, 2026
I had previously bought the Super 42 with an H1 buffer. I needed a little extra weight to slow down the BCG. These worked great to get my rifle to cycle properly. Fast shipping as always!
Pros:
  • Geissle quality is always top notch!
Cons:
  • None

Yeah Man!!!!

by B1NICE, Verified Owner from GA, United States Written on July 2, 2026
Just purchased 2 of these to convert my H-1 buffer kit into an H-3 option. Most economical way and in stock ready to ship option. Easy install and never opened a buffer before but all the spacers are already inside. Just swapping these to replace the steel weights.

install was a pain

by Joshua, Verified Owner from GA, United States Written on May 26, 2026
Brought this to change my H2 to an H3. Install was a bit difficult when lining up with roll pin in the plastic. Other than that, works fine.

basic tungsten weight

by on the wall, Verified Owner from KY, United States Written on January 20, 2026
Not much to say - it’s a weight. Made out of tungsten. Made by Geissele. Helpful to make an H1, H2, or H3 weight from scratch carbine buffers. It works.
Pros:
  • Simple
Cons:
  • cost

Geiselle quality - can be used in all buffers

by on the wall, Verified Owner from KY, United States Written on January 17, 2026
The first review stating these can only be used in Super 42 buffers is incorrect.

I have purchased at least 6 of these to change the weight of my standard carbine buffers. Pop out the pin to add one two or three to get an H1 H2 or H3 respectively. My last purchase I just unloaded all the steel weights in a PSA buffer and just made an H3 by adding 3 Geissele weights taking it to 5.5 oz. Just shy of a normal H3 weight.

These are easier to get and ship faster than ordering an H3. A bit more expensive that way but now I have options to go to H2 if needed.

Anyway, these work fine in any normal carbine buffer. Just lay attention to the order of the rubber spacers and the weights.
Pros:
  • Modular
  • Easy
Cons:
  • None

what you need

by Jason Edwards, from SC, United States Written on November 6, 2025
These are good to have have at least 2 Ezra in your parts box. Instead buying multiple buffers. You can modify your own. 1 weight is cheaper than the cheapest H1 buffer. Also it’s sold by Geissele. So you know its good.
Pros:
  • Peace of mind
Cons:
  • None

Making H3 Buffer Weight

by Marcus, Verified Owner from GA, United States Written on August 23, 2025
Cheap price and easy to install/adjust buffer weight. My one issue, maybe not for everyone, but the weights rattle a bit. So, I just shoved a small piece of foam in with the weights to stop it. Bought this weight to adjust the Geiselle Super 42.
Best Used for:
  • SBR
