I was playing around with the idea of adding a red dot to my G34 for GSSF. So far I've come across the C-More system that uses the rails. I've seen shooters at matches with a side mount "bracket" that holds the optics. 1) What optics are used with the bracket mount? 2) Who makes the bracket mount? For those that use either the bracket or rail system for their optics what do you use and how do you like it? Thanks.
