Buffers & Springs

[skp]

What is the advantage of the H6 buffer and who sells them?

Not much:

.. the H6 is completely unnecessary.

But Damage Industries sells something they call "H6 Buffer upgrade kits".

The H6 is what the government uses when they put a carbine receiver extension on an M16. They came up with the H6 to try to mimic the qualities of the VLTOR A5.

I guess it does good enough as they reported the same reliability in testing.

Was that testing conducted with the M855A1?

I don't remember. It was a few years ago though. I wish they would have gone with the A5. It makes a lot more sense on a 20".

I'm having a really hard time understanding what any of this means ^^^^^.

The H2 buffer was used with the M4A1 barrel because the mass of heavier barrel caused more bolt bounce. H buffers are used with the lighter M4 barrel.

It had nothing to do with 'gas'. Ridiculous heavy buffers are an M4c fad.

Basic physics; the mass of the barrel has nothing to do with carrier bounce.

And an H6 buffer? What the frak did the army do, re-inventing the wheel, to make it look like they actually had a clue? someone have a pic of a dis-assembled H6, so we can mock it mercilessly?

Basic physics. The mass of the barrel absolutely does have an effect on bolt bounce.

The H6 is the same weight as an H3, with six weights and a biasing spring. They also work very well in full-auto suppressed SBR applications, IME.

If both masses move as a result of the collision. Where does the barrel bounce to, then?

If one mass is immovable, then the bounce is determined by the elastic properties of the two masses and the closing speed.

Picture a 100lb anvil hanging by a rope.

Hit it with an 8lb hammer. Then hit it with a 20lb hammer. Same effect.
