Yes, thanks much for so well illustrating and explaining the flexibilty we (USMC) tried to build into the A2's rear sight back in 1983. Unfortunately, much of that was lost due to the Operator's Manual being limited to one basic "fits all" procedure; and the concrete being dried on so many 25 meter ranges common in those days.

Excellent post!! Thank you for the valuble info. I have already read it a couple of times and am applying it to my detachable carry handle sight base. Now I will have to head out to the range.
Will removing the detachable carry handle affect the zero once it is set??
I have a red dot coming in the mail (aimpoint comp M2) and will mount it when it arrives. I am a newbie to red dots an am wondering if the method for zero is different.

Molon,
like the above poster,
I am using a RDS. I do not get anything like the 50/200 IBZ. Granted, I am using a 10.5" SBR w/ 69gr handloads. However, I zero at 50yds, and even at 100 yards, I am seeing an approx 3-4" drop. At 200yds, I was about 6" low. Does the IBZ not apply to a RDS since one is not looking thru the rear aperature to the front?
TIA, and thanks for all your helpfuls posts. Truly appreciated.

Are you running Zone Alarm or any other Browser Security Program? I checked Zone Alarm is blocking www.box.net as it is a known site for distributing spyware.

Thanks I am!!! I will check Zone Alarm now.

Edited to add: Turned Zone Alarm off and the pics show up. Thanks for your help. Now I have to figure out how I can make ZA stop blocking box.net
