RED DOT SIGHTS NC 1x21 HDS 3AA

The NC 1x21 and HDS 3AA red dot sights were designed and built for tactical law
enforcement and military applications. Both sights allow rapid, accurate target
acquisition for close-quarters battle (CQB) and are built with rugged, durable single-
piece frames. The extremely compact NC 1x21 is ideal for use in confined spaces or
as a backup optic. It has a variety of brightness settings and is fully compatible with
magnifiers and night vision devices.

The tried-and-tested HDS 3AA is a perfect standard-issue red dot sight. Its multiple
brightness settings and precise step adjustments make it well-suited for use with any
assault rifle. Fully compatible with night vision devices, the HDS 3AA can also be used
with a 3x or 5x magnification flip-to-side add-on lens, allowing for extended viewing and
engagement capability.
