Components:
- fixed A2 front sight.
- flat-top A4 uppwer.
- EOTech 552.
I want to achieve lower 1/3 co-witness.
Will the YHM-220 EOTech Riser($39) give me that!? With an ARMS#40?
What other choices do I have? Will other non-EOTech-specific riser work? What's height do I need to rise it?
LaRue's seems to be quite expensive....
