    CFW-A bolt in 31K ot 31A?

    What spring is used with the A bolt in the 31A or 31K with the A bolt? I've seen videos from VegasSMG and Gaujo using the A bolt. I'm looking for a starting point to tune a spring without having to chop too many springs to get there.

    Thanks VegasSMG and Gaujo.

    Vegas reported the spring is an uncut standard CFW-A Bolt spring. I shall test in and report back.
