I’ve tried every (almost) Mount for my ACOGs (ta31, Ta01nsn, TA33). I’ve had bobro, Adm, larue, Geissele, SLR, GDI. my favorite mount for my ACOGs? Midwest Industries TAV1 for my TA31 and TAM for my TA33. My TA01 has the ta51 Mount cause clone rifle. I don’t know if they are better or worse all I know if they all return to zero good enough for me but I love the MI lever system and it’s considerable cheaper than the others. Any similar examples of this that you guys found in your quest for the perfect rifle?
