Hi,
I just installed a Knight's Armament RAS II system on my Bushmaster shorty which had an A-3 upper that I removed and made a flat top.  I then installed an A.R.M.S. flip up sight, and still have the original front post on the gun.  How can I zero this?  Any suggestions?  I have zeroed at 25 meters, and the gun is shooting 6 inches high at 100.  Would it be a good idea to just go with an EOTECH?  
Thanks

use the IBZ method as outlined here:IBZ

An EoTech is a great idea also.

wish I could afford one.

That's normal for a 25 meter zero. Mid range is about +10 at 200 yards. If you want it zeroed at 100 zero it at 100.

I use the Marine Corp 25 meter battle zero from the -10 with my A2's.Works perfectly for my needs on the range at all settings up to 300 meters.Allows for much more fine tuning of the sight at the distances I shoot.Have not tried it past 300 meters.No range available for that.Plus If Im going to shoot past 300 meters the 7.62x51 comes out.

Yep, a lot of people forget the "non math" sides to the military zero procedure. Little things like POA and probable target.
