Athlon Optics Talos BTR Gen II 1-4x24mm 30mm Tube Rifle Scope Second Focal Plane AHSR14 IR MIL Reticle Black. The Talos BTR GEN2 1-4x24 is as suitable for any AR-15 as it is for a short-range bolt action hunting rifle. On its lowest magnification setting you can expect extremely fast target acquisition with enough magnification to engage mid-range distances. The BDC-style reticle is optimized for the .223/5.56 Nato cartridge using 68/69gr BTHP but is compatible with a wide range of ammunition choices.
