I have an EOTech 552.308 mounted on my Ruger GSR and wrap around the FX II Scout Scope with foam in the Pouch. Plenty of room inside. Fit a set of gun cleaning rods and patches too with no problem. Attaching it on to a vest or backpack would be a challenge. That is why overall rating with four stars.
