SIGHTS
Depending on the particular platform, your rearm may have a mechanical sighting
system, which allows you to adjust for variations in windage (horizontal adjustment) and
elevation (vertical adjustment). The rear sight is adjustable for windage and the front sight
is adjustable for elevation. The rearm has indexing numbers (T-Marks) on the mounting
rails of the upper receiver and handguard to show locations for mounting accessories
such as sights and optics. These indexing numbers allow the user to safely place the
accessory back in the same location where it was mounted before being removed.
If your Daniel Defense rearm does not include mechanical sights, you can purchase the
Daniel Defense Fixed Front/Rear Sight combo (SKU 19-088-09116) from an authorized
dealer or from www.danieldefense.com.
4. 2.1
FRONT SIGHT
The front sight post can be adjusted up or down for elevation to establish the point of
bullet impact (zeroing). You may zero at any range (distance) you like, but after zeroing,
the front sight post should not be moved again. The standard location for the Daniel
Defense Rail Mounted Front Sight is the second-to-last T-Mark. The amount of change in
elevation per click varies depending on the sight radius (distance between front and rear
sight). SEE ADJUSTMENT TABLE ON PAGE 17-18.
4.2.2
REAR SIGHT
If your rearm is equipped with a Daniel Defense A1.5 Rear Sight, the large aperture can
be ipped back to bring the small aperture into use. A windage wheel on the right side
of the sight can be turned to move the aperture to the right or left to adjust for windage
(side to side). The standard location for the A1.5 Rear Sight is with the mounting screw
on indexing mark T-1 of the upper receiver. The amount of change in windage per click
varies depending on the sight radius (distance between front and rear sight).
