The CHPWS "Duty" optic is probably the one I'm most interested in of all the new optics they're showing off at the show. It's an enclosed emitter optic using the same footprint as the ACRO. It's also available with a red or green 3 MOA dot, as well as a multi-reticle 3 MOA dot, 48 MOA circle, or both. It uses a CR 2032 battery.

Like the other three optics from CHPWS, it has the following features:

- 10 brightness levels with the first two compatible with night vision
- 50,000 battery life with an auto-off after 5 minutes of inactivity and a "shake awake" motion control
- CNC machined from 7075 aircraft aluminum
