Holosun does not lie about it and
admits that +/- 1MOA error can be
expected. Due the position of the
lens, the error is more visible in hor-
izontal than vertical plane. During
typical use it has absolutely no
negative influence on accuracy. It's
acceptable.
HS403B-GR and HS403B are even
more simplified version of HS-
503GU. They both feature just a sin-
gle reticle (HS403B-GR has green
2MOA dot and HS403B comes with
red dot), adjustment turrets are bit
different and battery is located in
the bottom tray secured with two
screws. 4xx-series sights require
screwdriver or key (which is includ-
ed) to replace the battery.
