I have a GSSF coupon and torn between getting a plain 19.5 to be milled or a MOS variant.
Initially, I was thinking of getting a plain variant and milling it for P2. However, it seems that Holosun 509t is slightly better. Would it make sense to mill for an RMR and then use RMR > Acro or RMR > Holosun plates?
Any other thoughts/suggestions? Or is getting another MOS makes it easier?
