Im nearing the point of assembling my rifle and was wondering about lubrication points.  I checked the Maintenance/Lube forum for the basics of AR lubrication (usually in the context of after shooting and cleaning though) but wanted to see if there was anything specific or special to observe during initial assembly regarding lubrication?  Some parts come already assembled when received (BCG for example) so should I tear the BCG down and lube anything in particular?  Same question for the rest of the rifle assembly parts.  Thanks!

Clean everything (everypart-I use CLP)

Then apply a thin coat of CLP to all moving parts, make sure you apply Moly-grease to the barrel nut threads.  Thats about it.

ETA: Oh and yes always field strip the BCG clean lube and repeat often

Great, thanks.  Seems simple enough but I just wanted to make sure I didnt miss anything and have a "D'oh!" moment after she was together.

I like to use Moly-Grease on the appropriate trigger surfaces also, oils and lighter greases press out under spring tension. The Moly-Grease has enough body to have a little staying power. Some will argue this point (and their case can be made) as grease can hold grit. That said, I clean my receiver every time I take it out, long term build up is not an issue for me.

Thanks for pointing that out.  Something I noticed is that most all of the assembly tutorials (LPK, BCG, etc) Ive seen, here and elsewhere like Brownell's how-to's, do not include ANY mention of lubrication when assembling parts.  I found that odd.

I use Militec-1 it is a superb metal conditioner.  It bonds with the metal on a molecular level.  Needs to get warm to activate.  I coat all metal parts liberally with the stuff and heat them up (the oven on 100 degrees for half hour works well) before I assemble any parts.  That way, they will have a good initial coat of something to prevent dry wear.  All assembling of any metal parts in any other kind of manufacturing is done with an initial lubricant.  Think on the lines of an engine rebuild.  All the part are assembled with grease or oil of some sort.  I just like to be really thorough when it comes to my guns.  Don't wan't them breakin down later.
