Yes sir directly from Rugers website
"With all major components machined at Ruger's Mayodan, NC facility, the AR-556 offers consumers an affordable, American-made Modern Sporting Rifle with the rugged reliability they have come to expect from Ruger.
"The AR-556 is the first firearm designed and built in our Mayodan, North Carolina facility"
I have the 18" Ruger 556 MPR and I love it, its durable reliable, and is easy on the eyes. I dont yet have the pistol version but I'm sure that its quality as well.

Anthony, All USA made parts including the Magpul Magazine Sir. Cheers and you and yours stay safe!

Yes.

Ruger manufacturers most of the components on their rifles the Magazine included with this is a Magpul Pmag, which is also made in the USA.
The operations, shipping and manufacturing portion of Magpul is based in Cheyenne, while its headquarters is located in Austin, Texas
