    Any how, from what I remember, the standard BCM spring performed the best. I don't know if they tested Sprinco Springs but some of the standard springs from other companies didn't perform so well.
    I vaguely remember Rsilvers posting a lot of information relating to spring rates and duty cycles. I don't remember anything trying to match that up with perceived recoil though. You might search his name on the technical forum.

    Maybe that was it.


    *EDIT* - I just looked at his post. That wasn't it.

    16" standard BCM middy, I've used a carbine buffer and an H buffer and had no problems. The H felt a little softer so that's what stayed in it.

    What about buffers? Do they contribute as much?

    You really can't compare different barrels and gas sytem unless you know the port size.

    I have two BCM 16" Midlengths.

    One has the A5, Sprinco green spring, and the standard A5 buffer. It runs greats, I love the way it feels. I have only tried AE .223 and Fichocci .223, both ran fine. I usually run true 5.56 most of the time though.

    On my other one, I recently put in a Sprinco Blue spring with an H buffer. I am wondering how it is going to work.
    It is from the construction of underground FEMA camps. I can't say more because there a guy parked in front of house in an AMC Pacer. He is acting like he talking on the phone, but I know better.

    I have to sign off now & put my laptop in the microwave.

    Is there any law of unintended consequences with heavy buffers and aggressive springs?

    Damage to barrel extension or bcg or gas tube?
    Counter recoil killing optics like SCARs?
    Other...?

    Short stroking, especially with less powerful ammo.

    Not sure why someone would wander into Very heavy buffer and spring realm on a middy. Even if you have a suppressor.
