Be careful....

and be well aware that each type of buffer is specific to the rifle you use. This is because of the location and dimensions of the gas port, and the amount of gas that must come back to the bolt carrier group for proper function.

You can NOT simply put a carbine type stock on an AR15 with a 20 inch barrel for this reason. Ensure that whatever stock you choose takes the full length stock and buffer if you have the 20" barrel; likewise with the 16 inch barrel.
