 ar sight in at indoor range.  I want to sight in but am going to the indoor range.  Not sure of the dist there.  I want to be on for 100 to 200 yards.
  Where should I be hitting at say 30 yards to be on at 100 to 200.  I have the sig m400.

Open sights?

If that's the case zero  1" or so low at 25-30 yards. The flip ups sight are closer to the bore than the standard front sight tower. With a standard from sight tower and rear sight to match. A expedient 100 yard zero done at 25 yards would be 1.5 inches low but seeing the sights that come on a M400 are lower I would start with at 1" low and go from there.

That should put you on the Easter Bunnies head across a average living room.👍

I wish the indoor range here would allow rifle calibers.  I may have to check with the one in post falls and see if they allow them or not.
