I have a Mossberg 640T .22 Magnum bolt-action rifle that belonged to my father. While cleaning it, I broke off the bolt plate that covers the firing pin action. I have searched around online a bit, but parts seem pretty scarce for this particular model. Would the bolt plate for the 640K be compatible? I was able to find this part at Numrich Gun Parts. If it's not compatible, any ideas where I might be able to find the right part?
