I agree with the above posters: For those new to the AR platform, pictures are priceless. Thank you for setting aside some of your time to great a tool to help your fellow enthusiasts get the job done right.
A few small thoughts I had, looking at the pics:
1) Trigger & Disconnector are included as one unit (I have the same lightened spring on my trigger too, love it!) but might confuse someone if they aren't together in their parts kit.
2) Receiver is called a 'Rec'r' in one pic and a lower in the other. Might want to pic one term for consistency and, if Rec'r be sure to explain the abbreviation.
3) Grip screw, bolt latch, magazine catch, buffer tube, & related parts not explicitly shown as separate and labeled but this may come earlier/later in your pictures, so sorry if you've already covered it.
4) Placement of the rear takedown pin on the receiver in the 2nd shot makes it kind of hard to make out.
That's all I got at a glance, but it's a hell of a good idea. The hardest part for you I'm sure is taking your vast experience and knowledge and having to set it aside and try to get back into a "beginner's mindset" to figure out what a newbie would need to know. It all depends on your target reader I guess. I can see you doing a series, from basic build to accurizing, with your solid knowledge base.
Thanks again for giving back to the community and great work!
Thank you My Friend - For those forum members who know me, I would like to introduce a very good friend of mine, Mr. Clean, a very knowledgable guy when it comes to modern firearms and reloading. The man is a walking encyclopedia of knowledge and has one hell of a nice collection of firearms that I am most jealous of.

I would easily consider him one of the most knowledgable people I have met on the subject of modern firearms and their applications.
As for your points Sir: These were but two of over 100 pictures that I have taken in the installation process, but the real work is in the write up, that currently sits at over ( 4 ) pages of MS Word, and isn't close to being done yet. I will include the pictures, along with the written directions, and there will be terminology from the Heritage of Colt ( the true background of the firearm ) and a more modern terminology for ease of shopping. Several pieces, for example, will be referenced in both old Colt terms ( Receiver Extension Lock Nut ) and the more modern term used in gunshops around the country ( Buffer Tube Lock Nut). The intent is to provide as much information as possible, and have the pictures tell a story even a slightly blind man could follow. I hope.
As explained in the write up, I am showing a two stage drop in trigger, because I don't have a G.I. Issue to show the the separate disconnector and spring. I have referenced a really good book for any specfics not covered in the write up, so hopefully it will be enough for the average layman to be able to assemble.
There is no question that I am setting myself up for criticism with not labeling something
SPECIFICALLY as another person would have done it. But, there was another thread started on this subject that died on the vine & no one else
WAS doing it.
I did put up a post requesting anything specific that was needed, or someone wanted covered, by the forum that received ZERO reponses, so I am going about what I consider to be more than informative for the average person.
My interest in these first of many pictures is that they are clear by themselves. Could you take the knowledge shown and put Tab A into Slot B? If you can, than we are on the right track and, hopefully, the write up, along with the complete series, will not be met with much criticism and will help several people who are interested in the process.
*shrug* Only time will tell I guess.
Thanks for the feed back guys...
