Has anyone tried to put the heavy tungsten weights from a H2 or H3 buffer into a DPMS .308 buffer? If the weights fit, it would be a cheaper way to make a heavier buffer for the DPMS .308.




 

I never tried that. I ordered one of the heavy buffers.

I just got a couple buffers in from heavybuffers.com...you can feel the quality immediately. All my buffers needs will be settled there.

They sell just the weights too.

Who does? I'm interested in getting a couple to try.

 

Has anyone tried pinewood derby tungsten weights?

People have tried all sorts of weights.  Slugs, lead shot, washers, tungsten weights, tungsten powder, sprung weights, steel.

The different AR15 buffer weights are comprised of varying mixes of steel and or tungsten weights.

Since the modern SR-25 era AR10's use AR15 buffer diameters, but are shorter for the carbine and rifle length extension tubes, you can use buffer weights interchangeably from within the buffer bodies.

The important thing is to know what you are trying to accomplish with your cyclic rate, and dead blow effect for going into battery.  Here is an example of several different AR15 carbines being evaluated with different buffers and ammo, showing cyclic rate and carrier bounce:

AR-15 Buffer Test

Interesting. That was a lot more bounce than I would have expected.

For an AR10 build, this is one of the reasons why I talk about trouble-shooting the gun with high speed camera to get the gas port and recoil system balanced out.

It would be very fun to do a video comparing the DPMS AP4 16" CLGS to ArmaLite DEF10, for example.
