The United States has been at the center of Firearm history since its founding and preserving that is Old Arms of Idaho’s central goal. If you have a weapon system, old or new, we most likely have the parts to repair or complete it. If it’s not on our site, it’ll probably be here soon — we’re updating our inventory every weekday.
We’re constantly collecting Militaria of all shapes and sizes — checkout the 24-hour Gun Show.
Machine guns are incredibly cool, and we like to share the wealth.
We keep a fair amount of vintage ammo in stock at all times, and are always adding more to the store.
