I just did "my version" of the 15 minute trigger job and must say I am quite pleased!  I polished the sear engagement surfaces with 600 grit wet dry and JB Bore cleaner.  Now they're a nice mirror finish.  I did the springs as suggested and voila!  A sweet little trigger.  It is so smooth and light that I was afraid it wouldn't ignite the primer, but I threw in a primed unloaded case and it went bang. It left a pretty good indentation on the primer.  I am not exactly sure of the weight, but it feels around 3#.  

Better yet, I have a Superior Arms lower and they are tapped for a takeup screw.  I can adjust the trigger right up to the break point.  I have never felt a match trigger in an AR, but I can't imagine it being much nicer than this.  I was going to order a Jewell two stage, but I don't think it is going to be neccessary.

This was done on my target rifle.  I plan on leaving my plinking/defensive AR at it's current weight, but with a nice polish job.

Then you didn't do the "15 Minute AR-15 Trigger Job".

Well, I was going to say, "I did the 15 minute trigger job and then some".  I should have just called it "the improved 15 minute trigger job".  

I knew I would get a smoother trigger doing it the way I did it.  I didn't think just putting polish/rubbing compound on the engagement surfaces and dropping the hammer 20 times like you said to do would give me a trigger I would be happy with.  All in all it didn't take me much more than 15 minutes.   Thanks for the helpful guide.

The trigger and hammer sear surfaces are only surface hardened.  That is a very thin layer which is easily removed with any aggressive stoning or polishing.

Watch out for accelerated wear.
