I bought the Nordic Speed Bolt for my 930SPX. I have no problem with the bolt, it is a solid piece and looks great. My problem is with the shipping charge. They charged $8.95, when the envelope came, it had the postage stamp for $1.56!!! Even if you include the envelope and say it cost them $1, then shipping was only $2.56!! I feel scammed. Why not charge $40 for the bolt and say it includes Free Shipping? I know some companies mark up shipping, but this is at least a 400% mark up. I called them and left them a message, let's see if they respond.
