MILSPIN: The American Metal Company

If you’ve been involved in the aftermarket gun parts scene for a while, you’ve likely noticed a trend: quality-made, durable products made by expert craftsmen are in dwindling supply. That’s why MILSPIN was founded on a simple mission to deliver American-made products to patriots who will use them with pride.

But nothing we do would be possible without the sacrifices of our Armed Forces—that’s why we work so hard to give back to our fellow Veterans. All of our products are machined by the hardworking heroes who keep us free.
