Yes I have the GDI ACOG mount on three or four of my TA31s. The increase in FOV is great but it really is a disservice for shooting from awkward positions and can lead to scope eye (not that it hurts, more annoying than anything else)
Even another 0.5” of eye relief would really help the optic out. The 308 versions are great but then the BDCs are pretty off when you start shouting at 400 and beyond.
