It will get your attention when it does.

It matters at either ends of weather conditions, at altitude and as well as how clean or dirty the gun is.

For those who have been intrigued by the OP but don't know the answer to the question:
use the heaviest buffer you can get your grubby little paws on that still lets your gun run. |

It definitely makes a difference with a can.

I have used only H2's in all the AR's I have had for many years now. Never a problem and they do help reduce recoil some, which translates to less impact and beating of internal components. On an AR pistol or a heavy-er barrel AR carbine I would consider it mandatory.

A good buffer spring should not be forgotten as well, like Sprinco's.

Buffer springs and buffers help adjust the timing.
A lot of rifles have a pretty wide window. Heavy, light? They will run fine. Some have a more narrow window for a variety of reasons. That’s where being able to tweak spring and buffer weight become important. |

I know gas port size could be an issue but rarely do any factory guns come with more than an H1. |

Standard carbine buffer + agb for me.
Least recoil with a properly adjusted gas block (without resorting to non standard buffers, springs, or carriers), and with a quick turn of an Allen wrench (kept in the pistol grip) it can run dirty, in adverse conditions, or with light loads without having to worry about changing parts. I checked, and I can't quite fit a full selection of buffers in my MIAD. |

Generally speaking decent bolt velocity is a good thing. Let’s you run while being dirty, with weaker ammo, ext. For example, my mk18 was running a springco and a h3. Pretty oversized gas port, so I wanted to try and give it plenty of spring. Recoil was great and smooth, but when it got really crummy it would start to have failures to feed. Swapped to a colt carbine and h2 buffer and it ran flawlessly. That’s probably part of the reason most rifles don’t leave the factory with a stiffer spring/heavier buffer. Having slightly too much bolt velocity doesn’t lead to a rifle coming back. Too little does. |

Think of it as “tolerance stacking” in the machining/engineering world. There are literally probably a million different combinations to be had with this platform. Off the shelf stock/factory guns generally fall into the “mil spec” guidelines, and work just fine with standard buffers. Start changing shit, and a different buffer may be needed. |

I use Spikes T2's in most of mine, but have H in a few. My ejection patterns all are about the same.
Guy at my gun club had a FA & it was suffering from bolt bounce bad. He had to use an H2 & that fixed that. |

16 to 11.5 run an H buffer.
10.5 H2 |

I run my adjustable gas ARs with empty C buffers. I usually default to an H1 or H2 with fixed gasport guns, esp if using a can.

In a properly gassed unsuppressed semi-auto?
It really doesn’t matter. |
