Since you have taken the classes, how does the instruction address the use of rail-mounted advanced sighting systems that incorporate some degree of magnification (like the Advanced Combat Optic seen on most US M16s/M4s in Iraq and Afganistan)?
Basically, if you can see it, you can hit it. Mosby is a large proponent of optics over iron sights...preferably red dot sights, and if you have a magnification optic for your red dot to extend your reach, that’s good too. He likes the ACOG’s too but doesn’t run one on his weapon. He uses an EOTech.
The majority of the class was focused on engagements within 200 meters where enemy contact would be made.
From personal experience, you don’t want to use a scope for his class. I was using a Nikon M-223 scope for the first class. Getting a sight picture in various positions and while on the run was difficult to obtain quickly. Night fire exercises rendered them practically useless.
For the 2nd class I used a red dot sight. It made all the difference.
