As I understand it, Redfield was acquired by Leupold in this generation. This scope is warrantied by Leupold. Reticle was designed with bullet drop compensation but I don’t recall the details. This is a great simple, no frills hunting scope and was on my first rifle as long as I had it. Would work great on anything: rimfire, AR, bolt gun. I had it on a .270 and then a 7mm. Happy to answer any questions. OBO
