Pinning an AR-15 A2 rear sight

[TMC]

Does anyone have a link or information on how a A2 carry handle rear sight is pinned ? There was a sight GSWAGNER who posted start to finish the process to pin the sight but that was 2008 and now the site is gone. There are companies that do it for CMP shooters like White Oak Armament and people like John Hollinger who discuss it but I am interested in the machining process ,Are there any sites or members I haven't seen ? Any help would be appreciated. Just to be clear I know what it is and why it is done just interested in the actual machining and setup process. Thanks

I guess you don't know what a pinned sight is ,let me explain. Pinning an A2 sight is installing 2 o 3 pins below the A2 sight to square the sight to the carry handle and remove any play in the sight as the elevation is raised. The sight is guided on the pins. Pinning is often used on match grade rifles used in CMP COMPETITION. observe the pin between the sight body and the upper receiver body ( there is also one in the front ) .If you also look carefully you will also see the fine threaded elevation .This setup increases the accuracy in sight adjustment out beyond 600 plus yards for competition. It is expensive to have done as are the components that is why I am trying to find how it is machine. This is only part of the process the other step involves modifying the front sight mounting for finer windage adjustments as well as a modification to the sight pin I have all ready have done. All of this also involves match grade barrels , triggers etc.... believe it or not while expensive it along with hours of range time turns the AR into a tack driver kind of a step beyond mere sight installing. While you can buy match grade rifles the FUAC SAFE ACT has made purchasing the rifles almost impossible here,

Again come on I have had all those sights for YEARS. I am looking for the machining steps ,they use to be available but the web site is gone . Apparently no one has done the pinning them self here. I can buy carry handle uppers for $130. 00 complete minus the bolt and charging handle.The process to pin the sight is what I want .I really thought some here would understand doing the work yourself and avoiding the ever present "well don't you have the safe act you can't build these rifles in your state"

This is all I have as you can imagine there is much more needed to machine the sight

I get the concept it works as guild but some people would prefer to die before passing along some of their knowledge and experience
