I don't know but it would be cheaper that $100-$125. We will have to let the man know that we are interested in a group buy on SR-25 mags so he will check into them for us. I asked a man the other day if he had any for sale. He told me that they are as scarce as hens teeth. I told him but if you pulled out a $100 bill ten thousand people would be trying to sell you one. They might be scarce, that is why we need a group buy on them. For what you would pay for 4 of them, you could buy yourself another rifle or pistol.
