I was out in the field with my MRKII BRJ and the bottom of my magazine fell off and I have lost the base and the spring inside the magazine. Does anyone know were I can buy those parts, Savage does not sell them. If anyone has a damaged 10 shot mag that they would like to sell please post your reply.

Anyone know if their is a 10 round replacement plastic magazine available? Or a better metal
magazine not made by Savage?
Thank you.
Pete
