| What would be the best way to test different weight buffers in my ar15? |
| You can Google search.......something like "which AR buffer to use?".....and there are charts that suggest which weight with which combination of parts. That'll get you close. I'm guessing that your question is based on you don't have 4 or 5 different buffer weights on hand and you want to get to where you're going in the least expensive manor? You'll probably want to have the heaviest buffer that will still let the rifle function reliably. |

Buy H3. Shoot with one or two rounds in mag. Watch ejection and make sure it locks back on empty. If rounds trickle out and/or no lock back, remove roll pin and replace a tungsten weight with a steel one from the standard buffer. Repeat until satisfied. Test with at least 100 rounds to ensure reliability.
Swap buffers only after the rifle is well broken in. Works for me. ETA: Keep some Wolff or TulAmmo for function testing as well. In general, if a gun works with that stuff it'll work with any .223. |

This does not help you much on what to purchase but I have several AR's and the buffers comes apart with a pin. I could not tell you what any buffer I have weighs but I have added weight and removed weight from several buffers to get rifles to function better.
I would purchase the heaviest buffer you can find and remove weight if needed. Inside the buffer are small lead or steel weights separated by rubber washers. You can easily remove a weight and replace it with rubber or some other thing that weighs less. I believe the weights are the same diameter as a AA battery and come in lengths from about 1/2 inch to 1/4 inch. The buffer is filled with the correct combination of weights to reach the total weight of the buffer. I have even cut down a rifle buffer to a carbine length and removed the extra weights for use in a carbine buffer tube. |
