I'm sure this gets asked a lot but....I need to ask again.
Using a 16" 5.56 barrel with carbine gas, What buffer should I be using in a carbine stock? |

| A gunsmith told me that the 16" barrel was supposed to use midlenght gas. Most 16" barrels that I have seen are midlength but not mine. He said I would need a heavier buffer if I planned to shoot it much. He did not say how heavy. He said the carbine gas length was made to work with 14.5" barrels, not 16". |

Buffer size probably will not matter. It is more dependent on gas port diameter than people realize. If it is overgassed a little with hot 5.56 ammo, it might be perfect for the weaker stuff we see these days, especially budget priced import ammo.
Just start with the. carbine buffer. Try it with the ammo you intend to shoot. If you shoot full power 5.56 you might need an H2 if the gas port is large, but if you get an H2, you might not cycle low power stuff. You can start with standard carbine buffer and get a tungsten buffer kit and play with swapping steel weights for tungsten or steel/tungsten combos and tune that way. I have two 16" carbine barrels. One shoots 5.56 stuff a lot and needs the H2 buffer to slow bolt speed down some. The other is a precision target barrel shooting milder match ammo and needs the standard weight buffer. Experiment. Buffers and weight kits are cheap. |
