    All this talk about buffers (confused)

    Leads me to asking why?

    Heavier buffers will delay the opening of the action and lighter ones will do the opposite. It would appear that most shooters would like to have their rifles run smoothly and 100% without issues.

    But I think I am missing something in all this, if a rifle or carbine or SBR functions 100% why would one change out his/her buffer to another weight profile?

    Thanks

    You wouldn't, unless you are switching to a suppressed system, colder or hotter ammo.

    Agreed

    I guess then it is a matter of balance rather than function when chasing the optimal buffer (weight)

    Understood regarding the affect suppressors or different ammunition could have on the system.

    Thank you for the reply.

    It's all about controlling the cyclic rate.

    I run a "H" in both of my 16" mid-lengths.
    The bolt locks back consistently on the rare occasion that I shoot under powered Russian ammo.

    I run an "H2" in my 10.5" carbine.
    If I shoot the Russian stuff through this it short strokes constantly.
    If I wanted to run the cheap stuff through the 10.5" I would run a lighter buffer until I found the weight that would allow the bolt to lock back on empty.

    Cyclic rate is a combination of three things are at work that need to be in balance.

    Moving mass, spring force and gas force.

    Gas force is controlled by gas port size, location and ammo loading.

    True.
    But how many of these variables can be controlled by the end user?

    The snake-oil bolt carriers and colored springs can change things up a bit, but how reliable are they?

    Ammo and buffers are the cheapest and easiest way to control cyclic rate.
    5.56 pressure ammo and a "H" buffer works well in 16" carbine and mid-length guns.

    In agreement again

    Excellent point!

    Also valid, as a smaller part of the cyclic rate control factors... I do not consider these a good approach.

    Ammo and buffers are the cheapest and easiest way to control cyclic rate.

    Port pressure and dwell time comes from the ammunition and port size, for the most part we cannot control the port size unless we choose to use an adjustable gas block.

    5.56 pressure ammo and a "H" buffer works well in 16" carbine and mid-length guns.

    Lot's of If's associated as the specific chamber and port size have major impact here. So I take this to mean when a true spec chamber and port are present.


    Once again thanks, my understanding is getting clearer.

    I guess it is that simple. Key factor is achieving the balance which equates to reliable performance and lower wear rates. I find it interesting that with only one exception I can think of (a low mass carrier) the solutions always seem to go up in weight or spring force...

    This touches on something I've been thinking about and would like some clarification on.

    Buffer weight vs heavier spring. What is the difference between going from a standard spring and car buffer to

    a. standard spring and H2 buffer
    b. blue sprinco (heavy) and H buffer

    How does the spring tension vs buffer weight affect the function/recoil/bolt bounce etc...? What different affect does each have on the weapon?

    Just curious and looking to learn.

    Thanks,
    Harold

    I saw a guy who had a Carbine buffer in his silencer fitted M4.

    His gun ran. But the plastic buffer tip was about mushroomed over from slamming into the back of the RE with the force of Thor's hammer.

    So although his gun was running, he should have jumped up at least two buffer weights. His gun seemed to function 100%, but it definitely wasn't the right buffer.
