Like the title says I have a sterns m&p, sig 320 mag block forsale. Slightly used 2 to 3 hundred rounds threw it. Function flawlessly. Only reason for selling is I finally got a nordic components pcc lower for the m&p mags. Any questions feel free to ask. $125 shipped in the 48. If you are looking to run a m&p 9mm mag AR this is the ticket.
