Would you all now consider a Gen. 5 MOS gun a suitable base gun for the Acro? Meaning since the Acro has a cross bolt mounting system and you are deleting the short screws used on other RDS. Basically eliminating one of the weak links in the mounting. I know that milling a slide will always be the best option. Would you now consider the MOS system to be more usable/ robust using the Acro vs. the RMR on a MOS?
