C4 Diopter Sights
Centurion Arms C4 "diopter” style iron sights are for use with AR-15 or M4 flat
top receivers. The sights are designed
to the correct ergonomic height for the standard AR-15/M4 flat top receivers in
any of the popular calibers including (5.56, 300BLK, 9mm ect) for the proper
feel and rapid sight acquisition. The
rear drum has four different apertures, allowing the shooter to rapidly adjust
for different light conditions. It uses
a standard HK type adjustment tool for windage and elevation. The front sight mounts to any commonly
available same plane rail style hand guard that is the industry standard. It uses a standard fixed blade which can be
replaced with the tritium front sight blade commonly sold for the HK91/94/93/
and MP5’s. Both front and rear sights
are also compatible with any standard AR-15/M4 sights, including any standard
height back up iron sights or the detachable carry handle rear sights. This offers the shooter maximum sight
options. The Centurion Arms sights
also take up a minimal amount of rail space leaving plenty of room to be used
as back up iron sights in conjunction with Aimpoint, EO Tech and most other
readily available red dot sights.
