Visit? That's sounds great ! Take bunches of photos if allowed.
I spent three months in the Remington factory in Illon, NY. No photos, the Security was Federal, and was very tight. Everything was under cameras.
Also, a Browning FN plant in SC, made US Miltary Machine guns.
But the best was in Waterviet,NY, the oldest Arsenal in the United States. They made all the big canons for the Military. I mean BIG ! The whole Arenal is a Historical Site.
