1) I bought an Eotech XPS OPMOD for my RRA AR-15. It is basically an Eotech XPS with a 7mm riser for a lower 1/3rd co-witness with iron sights. I plan on shooting this rifle within 50 yards or less. This is of course until the end of the world scenario happens and I may be forced to make longer range shots. What yardage would you suggest I sight in my Eotech at? (I have my irons sighted in at 25 yards as per many discussions I have read)
2) Secondly, I bought Ruger 10/22 tactical and placed a TruGlo holosight on it. The sight is affordable, and offers the same outer circle with center dot configuration as my Eotech. This makes the Ruger a good/cheap practice plinker for my AR. What do you suggest I sight this red dot sight in at, keeping in mind it will also be used at 50 yards or less as a practice rifle?
I ask you all because I appreciate and admire your advice, and I always learn from you. Thank You.
PS- I'll post pics when I can get my wife to explain to me how to work her Digital SLR
