This Burris 1x20 Sight includes the Ballistic QC-1X Reticle which has bdc etchings out to 600 yards. Since the reticle is etched into the glass you can still take the shots you need to even if the batteries go dead. This optic is powered by a very common and inexpensive AA battery. You can expect 5000+ hours of battery life from a single AA battery. Due to it's construction this optic is also very shock resistant. The AR-1X is both water proof and fog proof.  You can choose between five different red and green brightness levels. The parallax is very minimal even at 100 yards.
