So in my last blog post, I gave you a number of Youtube videos you can watch to learn how to assemble an AR lower.  In this post, I’ll give you some web pages where you can visit them and read step by step instructions with photos.  This way, you can print you the pages and have them by you for reference if so desired.  As with the videos, check out all of the links and see how the authors do the assembly of their AR lowers.

First off, AR15.com has an assembly guide you can check out:

Here is one from the Arms Guide:

The Truth About Guns has a guide:

The New Rifleman does as well:

I hope this helps you out!
