Every buffer I have handled has had the rattle of the internal weights moving around. Is there any reason they are not held more tightly in there? I took two buffers apart and there are soft spacers between the metal parts to maybe keep them quiet.
The main reason I ask is I have convinced myself making the weights tight inside the buffer would smooth the action. As the round fires and the buffer moves back, the weights are toward the front. As the spring reaches maximum compression and slows the buffer, the weights will flop to the rear. Yes, this is where the polymer end is, but the inertia of the weights still moving and then hitting the end seems to mean a more jarring reverse of direction for the buffer than if the weights and buffer moved as one. As the buffer moves back toward the front, the weights will slam into the end of the buffer, again making for a more jarring stop. Is this enough of an issue to really matter? That I don't know. It may be lost in all the other stuff moving that it doesn't matter, but I can't leave well enough alone. So, before I work this out, is there a reason the weights are loose in the buffer? |

Isn't this a place to ask questions? Instead of coming here, just search the web? Ha, and btw, Google is an anti firearm company so don't use them. But to answer the question: the weights are meant to move which causes inertia to keep the bcg from bouncing out of battery after cycling. |

If nobody did their own research and just simply started a thread about their question, this entire forum would be clogged with (even more so than it already is) "Which AR should I buy?" and "How do I disassemble my AR?" threads. That would detract from the people who have complex issues that actually need an educated diagnosis. OP could have very easily answered his question with a quick AR15.com or "insert your favorite search engine here" search. Either way, OP, to answer your question, it helps to prevent bolt bounce. They are supposed to slide around inside the buffer. |

Does not seem logical to me and just curious. |

I don't think you were getting crap. But it's not uncommon to have people ask basic questions here, and then complain when they didn't get a spoon-fed answer within ten minutes of their posting. It is also important to note that ARFCOM is absolutely full of individual personal opinions, and full of people who have more or less factual information; this winds up with people posting firmly held opinions rather than fully backed up facts. So if you research beyond ARFCOM, you wind up getting a broader picture of whatever it is you're asking about.
The only buffer that I know of that doesn't rattle is a 9mm buffer - the standard 9mm buffer has a solid weight, rather than reciprocating weights. For a very well presented comparison of the various kinds of AR buffers, check out this archived thread from way back in 2009. |

Does not seem logical to me and just curious. It helps to distribute the energy of the BCG returning to battery over a longer period of time. Think of it like a dead blow hammer. Bolt bounce really isn't an issue in semi auto guns, but either way, that's why there are reciprocating loose weights in the buffer. ETA: Unsure on the JP Silent Capture, as I've never even touched one, let alone used one in a gun. I would assume it has reciprocating weights or a tungsten powder (sort of like the Spike's Tactical ST buffers) of some sorts in it, but I could be wrong. |

Have you ever used a dead-blow hammer? It's the same idea. The fact that the weights move allow them to absorb energy. It's what makes the buffer a buffer. This. I will say that both of my RRA carbine buffers don't rattle as much as my no-name el cheapo buffers, but rattle is absolutely normal. Heavier buffers won't rattle as much due to aditional weight and a tungsten filled buffer like Spike's is quiet. |
