Description

The Holosun AACW1.4 is an absolute co-witness riser for Holosun 403 and 503 series micro red dot sights. It raises the optic to a 1.4″ height — measured from the rail to the center of the lens — so the dot sits level with standard AR-height iron sights for a true absolute co-witness sight picture.

Machined from 6061 T6 aluminum with a hard-anodized finish, the riser installs onto any standard Picatinny, Weaver, or MIL-STD-1913 rail via a cross-bolt and clamp, holding zero through repeated fire. Note that Holosun optic bodies sit slightly taller than Aimpoint T1 optics, so this Holosun-specific riser is purpose-built to deliver a correct absolute co-witness with the 403/503 series.
