Frequently Asked Questions

How is the RMS2 different from the original RMS?
Shield removed the RMS’s separate battery drawer to strengthen the housing and fit updated electronics in the same compact footprint.

Can the RMS2 co-witness on a Glock MOS slide?
Yes, paired with Shield’s matching low-profile MOS plate the RMS2 sits low enough to co-witness without needing suppressor-height iron sights.
