Network Support III
For those of you who are looking for a way to mount a RMR while retaining a rear iron sight, Springer recently introduced this adapter plate which includes an integrated dovetail to install a rear BUIS. It’s compatible with the DPP footprint pistols, which currently includes the M17, X-Compact, and X-Five Legion. Sig is in the process of transitioning at least the rest of the X-Series guns to this footprint as well.
This is currently the easiest method for running a RMR without sacrificing your rear BUIS, at least to my knowledge
