All red dots are not created equal. The Freedom RDS (red dot sight) changes the game when it comes to consistency and durability in a red dot sight. This BDC model comes with a pre-calibrated dial for 5.56/.223 55gr rounds that lets you accurately adjust the dot out to 400+ yards.We took our 70+ years of optics knowledge and created a red dot that's built Leupold tough, performs in extreme conditions, and won't break the bank. This true 1x sight has everything you need in a red dot and nothing you don't. And like all Leupold riflescopes, it's designed, machined, and assembled in the USA and guaranteed for life. Includes one piece AR-specific mount.
