Seller

KYGUNCO is your professional and dependable firearms retailer. We operate two awesome retail stores in central Kentucky in conjunction with KYGUNCO.com. Over the last 78 years we have strived to make purchasing firearms simple for the law-abiding citizen. Our customers love our no-nonsense way of doing business. For the customer this means fast and free shipping on thousands of firearms at a competitive price, but without the hidden fees, credit card fees, club memberships and the gimmicky pricing tricks other retailers try. Straight Foward-Simple-Honest, that is how we've been doing it since 1946, and we don't plan on changing.
