    I recently got a MK II but have a problem with the bolt/firing pin. If you pull the bolt back and let it go forward gently it works properly, but if you pull it back and just let it go, it sets off the firing pin. I have replaced all the springs and am guessing it is the sear????

    Sear spring. Bet its bent.

    I've got a scar on my foot from exactly your issue.

    I am guessing you were pointing it down when you cycled the bolt. Thanks for the info. I will order one

    Could be bolt stop pin, spring or disconnector assembly.

    I looked at the sear spring and it looked fine to me, I was just going to order a new one since they are only a couple of bucks. But after this I have replaced about every spring there is.

    I will look at the bolt stop pin....I am not sure
