What does the extra weight do? Do I need one? I saw on Bravo CO. that there are 3 different weights, which one is for what? I have a 14.5 w/perm. attached extended A2, would the extra weight be good for my rig? Thanks!!

A good test for buffer weight is to load and fire one round at a time and see if the bolt locks back (after the rifle is broken in - 200rds min). If the buffer is too heavy for the load the bolt won't lock back reliably.
I like to use the heaviest buffer that is reliable. The H2 buffer is basically the same weight as the rifle buffer the AR was originally designed to use and the carbine action spring is only slightly stiffer than the rifle spring. A lot depends on the size of the gas port so experimenting is necessary if you want to optimize performance. |

I disagree with the breakin statement, there is no such thing as a break in period for an AR15. It will function the same at 200 rounds as it will a 0 rounds. |
