I wish I would have taken a picture of the spring before I broke it. I fitted it several times to make sure it was in the correct position but the U shaped bend in it wouldn't compress enough with the magazine locked into correct position. I never even got to swap out the cocking piece because I could visibly see the sear with the trigger pulled not dropping enough for the cocking piece to move forward. I'm just hoping that for some reason Numrich sent me a hair to big spring.
