Regarding the AR15-A2 rear sight:
For those of you who shoot across the course DCM Service Rifle or NRA high Power, what do you do about zeroing for the 200 yard standing (off-hand) stage?
I understand that the 25 and 300 meter range zeroes are the same because the bullet path cross the sight plane at those two distances. But the A2 sight starts at 300 and goes up to 800 from there. It seems to me that the only way to zero for 200 is to turn the front sight post upward with the rear sight set at 300. (And yes, I realize the sight is graduated in the Metric system while the NRA/CMP ranges are marked in the English system.) But if one does that, the sight will not be correct at 300 for the rapid prone and sitting stages nor at 600 for the slow fire prone stage. Do you just count the clicks on the front post and change it once you're done at 200 (during your first 300 yrd prep time perhaps)?
