Daniel Defenses Fixed Front/Rear Sight combo is both lightweight and durable and complement to each other. They are machined from 6061-T6 aluminum with a military specification hard anodized finish. The one piece design makes it easy to install on any MIL-STD-1913 rail and it secures with a slotted fastener threaded into a self-locking stainless steel thread insert. The concave radius on either side of the sight is a great place to rest your thumb for easy ambidextrous activation of the light.
