Dropping buffer weight with a "tight" gas port?

[Clint]

Good info.

The different gas system configurations can act a little differently.

It’s an 11.5" SS carbine length barrel I got from PSA. I don’t recall the original port size.

When I say the buffer weight made no difference, I mean it made no difference operationally. Both buffers functioned fully on the same gas setting. Both buffers would eject but not lock back when the gas was closed one click. Same when the H2 buffer was tried. But buffer weight made a significant difference in how the recoil felt. Recoil was uncomfortably sharp with the CAR buffer. It was softest with the H2 buffer.
