Help with using A2 iron sights with the 6.5 Grendel. - Lockdun1 - 07-08-2019 Well as I said above I’m wanting to use my m4 upper primarily with the irons. Specifically the F marked fsb and m4 detachable carry handle. I know that the sights are calibrated for 5.56 and they have charts to use based on what load you are using. What would I need to do to make a new chart for A2 sights for use with only Wolf 6.5?

I used the same method I do with my other fixed sight junk for sight in.Its an ribz that gives me the 100 yard zero option on the drum.

The detachable carrying handles are limited to 600m elevation, whereas the A2 upper receiver has an 800m elevation wheel. I would zero at 100yds, then work out your elevation adjustments once you know which increments your particular rear sight elevation drum has (1 MOA vs 1/2 MOA). Once you know what MOA value your clicks have, you can chronograph your load and work out the table with a ballistic calculator, which will give you click values for each distance. One thing I do on my M16A2 rear sight elevation drums is mark the increments with a paint pen so I can see them easily.
