Is a standard buffer on an AR heavier or lighter than after market buffers?

The only things affected by buffer weight are cycle speed and how the recoil feels. More weight means a slower cycle rate and (in some stock setups) slightly heavier percieved recoil.
The carbine weight is heavier because the M4 is full-auto. The M16A4 is burst and has a lighter weight. The M4 cycles slower and is easier to control on FA than the M16A4 would be. For most people. A rifle will still function with a very light buffer. The Simunitions, for example, have an aluminum replacement buffer that simulates the same cycle speed with the lower energy rounds. You can still fire the rifle if you forget to replace the aluminum buffer when you switch back, it just cycles really quickly. In a semi-only rifle, any buffer is pretty much as good as any other. |

Someone correct me if I'm wrong, but part of the reason cycle speed is affected is that bolt remains locked for a longer period of time with a heavier buffer. This can affect the function of certain guns, especially those with short barrels. On blowback ARs such as those in 9mm, the buffer helps control how long the bolt is locked to allow pressures to drop to a safe level before opening. |
