    Buffer spring rates?

    Looking for pressure rates of the various buffer springs available. Not just the weights or dimensions of the springs, or the buffer itself, but the actual ft. lbs. of energy they exert.

    Anyone have that info?

    May I ask why?

    Wouldn't that be a linear equation? I would think that a spring would exert more of the force it is capable of as it became more compressed. At the very least, it would be a 'mass x energy' type of equation. Also, I think the data would vary. What are the controls for finding accurate data? How would it be collected to positively reflect exactly what you are looking for? I don't think anyone has ever gone that far into depth on the subject. At least nothing that I have seen. I'm curious as to what relevance this information holds as well.

    It's definitely a valid question.
    One I've often pondered myself.
    Actually, I'd be interested in the data also.

    I'm slightly interested myself. I'm just curious as to how the data would be concluded and what it would be relevant to.

    Are you planning an ejection pattern reverse corralation regression analysis?

    Is that fancy talk for "where does the casing land with different spring rates?"

    Beyond that everything else is a crap shoot.

    I guess. I just plucked a bunch of 5 dollar words.

    You got a pretty good bargain...at least two of them are $8 words.

    I'm considering a custom build, and without getting too far into the details about the recipe before the pig is cooked it would be helpful to know the different spring rates, as far as what amount of force they exert.

    It would be a linear equation however there are quite a few very important details missing before one could derive the right numbers, such as the modulus of rigidity of the material, number of coils, wire diameter, outer diameter of the spring, Lfree and Ldef, and the applied load on Ldef.

    I was just hoping someone had a published list of the rates on hand, like for example "the standard carbine buffer spring rate is usually 18 ft lbs." or something similar.

    I guess If needed I could secure a standard carbine in a bench vise and use a pull gauge on the charging handle to measure pounds of force to compress the different springs...
