Rattle in Carbine Buffer

[steve2071]

I' ve got two Ar's: One i've completed a while ago and the other I'm in the process of completing. On this latest one, I had an unused carbine buffer lying around that I've placed inside and it has a little rattle to it, kind of like there are loose pieces inside. On my older AR, I've got a pretty solid feeling buffer in it and besides the "sproing" when I shoot it, it makes no other noises. They're both identical basic carbine buffers, gray metal with clear/white plastic. Does anyone else get the rattle? Will it cause me problems? It's probably insignificant but inquiring minds want to know. Hehe.

If by rattle you mean the tungsten/steel weights which are inside of the buffer clacking back and forth when you shake it along its long axis? If so that's entirely normal...

You learn new things every day. Thanks James.

To elaborate a bit, the weight was added to the buffer to deal with bolt bounce. It acts kind of like a dead blow hammer. It is an improvement over the solid buffer.
