I feel like new builders, especially ones who don't already own an AR platform rifle and have not really gave one a good look over, might be intimidated when seeing the parts list. I remember the first time I poured a LPK out on to my table and just thought "shit what did I get myself in to?!" but as soon as parts started going together, it was much easier than I had it in my head...kind of the whole "anticipation is worse than the event" deal. Once I built my first one I was hooked and have never bought another complete rifle since. Some of my shooting buddies spend the big bucks on the high end big name AR's and scoff at my "home built" ones, not realizing some of my guns are actually, IMO, better than even the best complete rifles to ME, since I customize each one to exactly what I think is best for what it's for...I also make one off parts once in awhile, usually out of Ti, that you just can't get...makes it that much more fun. I second everyone who said satisfaction is huge when building your AR...even if its the cheapest parts you can find, you will know that gun inside and out, down to every little spring and pin, that in itself makes you a more confident shooter IMO.
