After a good bit of shooting my "off the rack" factory AR's, I'm preparing to build my first "home built" lower receiver.

Where can I find the BEST, most complete set of directions for doing so? If anyone who has done it would like to chime in with some advice, please feel free to do so.

I've universally heard that it is easy to do, but I plan for this to be a "working rifle" for serious social occasions, and would like to avoid Mr. Murphy as much as possible. Thanks.
 
Just make sure you do a couple of things...

1. Use some electrical tape to mask the area before driving in the bolt hold open pin.

2. Make sure you reinforce the "ears" when driving in the trigger guard pin. You definitely don't want to break one.

3. Do you assembly AWAY FROM ANY CARPET. You are guranteed to lose a spring or a tiny detent like the ones on the takedown pins.

I did a couple of things that made the assembly go a little easier.

1. Took a photo copy of the parts break-down and placed each peice on top of the photocopy. This makes sure all the parts are there and if the breakdown is labeled you have the part name right there.

2. Take a 1/4" bolt or wooden dowel and drill a 1/8" hole crossways near the end. This is for installing the pivot pin detent. Place the bolt or dowel through the lower pivot point lugs and line-up the hole you drilled with the detent hole. Drop in the spring and detent, compress with a punch and twist the bolt/dowel to keep it in place. The bolt/dowel is then used as a slave pin and is pushed out of the way as the pivot pin is pushed in.

3. I took a section of G.I. cleaning rod and on each end drilled holes that fit the bolt release and trigger pivot rollpins. This let me keep the hammer a little farther from the receiver. This is just used to get the rollpins started. I drove them flush with a regular punch being careful not to mar the finish.

Sounds good. I'm making a list of tools and stuff I could use for the assembly.

Electrical tape won't leave a sticky residue on the finish?
 
I used 2-3 layers of duct tape as well.(just a little more protection from surface damage.) If it or electrical tape leaves a residue a little mineral spirits will take it of and not hurt the anodizing on the receiver.

Do a search on google for ar15 assembly and look for Bryan Lane. This is where I found my instructions.

P.S. the duct tape just has to hold itself in place. You don't have to rub it down, just touch it to the receiver.
