Sighting in 2 DD M4's at indoor range??

AR/M4 AR General Discussion

Any suggestions on sighting in my 2 new DD’s M4 in a indoor range that you can use rifles at, do to the very cold weather. I was thinking of 2 inches low at 25 yds would be a good place to start ( should be on at 100 yds if I remember correctly)then do fine tuning when weather gets warmer. Any thought’s or suggestions Gentleman? This will be basically so I can get some range time in and put some lead down these new tubes.

1.5 inch low would be better if you’re talking irons… maybe a little lower with a lower 3rd Red dot sight.

Then fix it with a good zero when the ice melts… at least 50 yards.

POI at 1.5" below POA is what you want for a 100 yard zero shooting on a 25 yard range. POI 1.2" below POA for a 50 yard zero

Give these a try, they offer both a 50 & 100 yard zero with a 25 yard range:

Thanks for the replies. Yes I will be using iron’s first, then one DD has a Eotech and another a red dot. So I will be sighting those in (maybe) at the same time.
