    Without going over too many basics, let us say we do a compare and contrast. An H2 carbine action in a properly gassed system would have a certain operating range or span of use. An A5H2 in a properly gassed system would have a certain operating range or span of use. How do those compare? Would, or could a wider range of operation be judged as a possible negative in shoot ability? Some systems may shoot smoother, some may not depending on what is actually going on. When you study the system in operation, some things can become clearer. Timing of events can be crucial to understand how the two systems contrast.

    Different things can do different things but in what ways they are different depends on the differences of the specific differences and how they effectively differ from each other.

    If you take a narrow selection of the carbine H2 operation that only includes the system barely bottoming out the action spring, then, that system may be considered more shootable than another in use. That does not mean that it would be better or best overall, that would be a possible selection of that system.
    An A5, in reference may have a wider degree in gassing range to operate, that doesn't mean that it automatically has the most preferred felt recoil in function. It depends on how you could compare the two. It may, or may not feel as good in function. The system still can have the ability to operate within its own range, comparing recoil between the two depends on their own reference point. So yes, different things can do different things, it just depends.

    If you took a sample of operation of an H2 carbine and superimposed that to a possible A5H2, how could those compare and contrast? You could note that the centerlines do not align, that would seem to result from differences in time that either operate in.
    What possible span of operation would be preferable to most? The wider span, or the shorter one? Sure, different things can be different. That does not mean a wider span of operation isn't available, or a negative determined by "feel". That would or could be short sighted, just depends on how on how things can turn out.

    So change one variable and all variables change. I think I get the basic situation now. No way I could ever perfectly fine tune things nor one size fits all. It would always be subjective for me. If I can just get in a safe subjective range I will be ok. I'm thinking h2+h4 would serve any need I might ever have.

    This shit is getting too sciencey for me. I'm just gonna keep mine at the heaviest it will run between H1-H3. If I notice a lot of reciprocating mass, maybe I'll drop the weight, but so far my wife's BCM has worked well between the H2 and H3 and about 1,500 rounds. My new Noveske is definitely getting one too, that thing has more recoil even though its got a dedicated brake vs the BCM comp.

    Tom is tripping me out. A5h2 is 5.3 oz I think, making it heavier than a regular h3 but will run a 14.5 mid length and tula where the h3 proves to be too heavy. Riddle me that Tom!

    Anyways, wider operation span with a5, don't throw it out the window with an a5h4. An a5h2 will run all your uppers while minimizing the abuse on parts with a regular h2. I would start with a5h2 or a5h3.

    I think vltor named the buffers based on what carbine buffers they'd replace. If your uppers ran best w an h3, than use a5h3. If it ran best w a sprinco blue and h2, run adh2 w a sprimco green.

    A5H0=3.8
    A5H1=4.56
    A5H2=5.33
    A5H3=6.08
    A5H4=6.83

    H=3.8
    H2=4.6
    H3=5.4
    HSS?=6.5

    I stand to be corrected on those...

    Seems like A5 is 'longer spring and one step up'

    Not sure what that means other than I would expect slower overall response for equal values.

    An A5 will run with a heavier buffer than a carbine system because the spring on an A5 is a lot lighter.

    I think the A5 is a great system, and a better mousetrap overall that the carbine system. But in all reality, with a properly gassed barrel, it doesn't do anything significantly different than a carbine system.

    I'd get rid of an over-gassed barrel long before I swapped the receiver extension, spring, and buffer to optimize functionion with a sub-optimal barrel. Even if it was an over-gassed Noveske or Daniel Defense.

    I wouldn't say that a rifle spring is a lot lighter, compare the Colt rifle and carbine springs in a simplistic fashion of L1 vs L2. If that basic comparison is made, sure more mass is possible, but there's more going on. The timing between the two can become more of a thing to look at. If you don't use up extra work to overcome tensions and stresses, that extra mass can go towards function. More mass options happen.
    It is true that a barrel that is closer to the proper amount of gas to drive through better porting and gas system lengths could be the in system to be more important in span of use than a more timed base action system. That alternate could also be argued, depending on where they are in operation for either.
    Knowing that both can have specific advantages that are not mutually exclusive overall, can mean the potential of a wide span or spans of operation may be had in conjunction within a balance.
    I know this whole thing sounds vague, but there's no way for me post all the preface for this now. I'm running on limited sleep, so call me out if you want, I'll try to respond later on things.
    For what it is, good, bad, or indifferent. The system as we know it now, cannot be the ultimate pinnacle of what it can be. Nor can it be the pinnacle of what may be without alterations to the base system that could make that happen.
