The lightweight streamlined design of the Daniel Defense Rail-Mount
Fixed Front Sight makes it unobtrusive and snag-free. 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. Special attention was paid to facilitate the use of
compact weapon-lights forward of the sight such as the X300 TLR-1
etc. The concave radius on either side of the sight is a great place to
rest your thumb for easy ambidextrous activation of the light.
