The Wizard

I hope this is the right forum. I just got an ArmaLite AR10BA2 (you know the one that looks like a 7.62 mm NATO M16A2) and I am wondering if the numbers on the rear sight elevation drum actually correspond to ranges for the 7.62 mm NATO ammunition.

Can a DPMS AR-15 Teardrop Forward Assist Assembly be used on a Armalite AR-10B Upper Receiver?

No longer looking for this item. Got one.

That sounds like a lot of work. Besides sending rounds down range is so much more fun than looking down the barrel.

This weekend I am planning to take out my newly acquired ArmaLite AR-10A2 for the first time. To be perfectly clear this is the one that looks like an M16A2 but in 7.62 mm X 51 mm NATO! I want to initially zero for 200 meter at 25 meters. I will then refine that zero on the 200 meter range. I have been looking on the web but I cannot seem to find a clear answer to my question: For a 200 meter zero using NATO standard ball (M80) ammunition, at 25 meter where will the point of impact (POI) be in relation to the point of aim (POA)? I just need a specific distance. Nothing more; nothing less.

He would probably want my left testicle, right arm, my first born and my 401K for it. Even though I really would like to get one I will not deal with JERKS. As for confusion statement, after I posted my WTB, I received three message from people saying they had one for sell. I requested their asking price and pictures. All three were current production rifles. None had a bird cage flash suppressor, bayonet lug or A2 sights. I added the secong posting to insure people knew exactly what I was looking for.

There seems to be some confusion on the part of some people as to for what exactly I am looking. The rifle I am looking for looks exactly like an M16A2 but in 7.62 mm X 51 mm NATO. Since pictures are worth a thousand words here is a link to a video that shows the rifle I want starting 17:09 minutes: https://www.youtube.com/watch?v=h7Z9o_gJtq8

The one with bird cage flash suppressor, bayonet lug, forward assist, updated bolt carrier and fire control parts. Post assault weapons ban variation.
