The Keystone Armory

The Keystone Armory was established in 2010 to bring the Erie area a new kind of gun buying experience. Our goal is to provide the area with a customer service oriented business with a clean, exciting, and inviting atmosphere for both first-time buyers as well as gun enthusiasts. Our Pennsylvania company has grown to become the largest gun store in the area. We proudly buy and sell a variety of top-quality firearms, ammunition, optics, suppressors, and accessories from the top manufacturers in the industry.
