My build.....AR build anyways.

I can too ( in my pocket) lol. I fully understand the whole AR customization thing, to each his own I say. As for me I never saw an AR platform as anything other than a decent utility rifle so if I were looking to save I'd buy cheap. If I were looking to customize I'd buy the very best quality that there is even if it had to be one part every 6 months. Either way it's a fun and personal learning experience.

I will say this do not skimp on your barrels. Buy the best and here is as fool proof a way that I know. Look up top level High Power shooting. See who is winning and look at the equipment list. You'll notice what brand is currently at the top. This doesn't have as much to do with the barrel maker as it does the lot of steel they purchased at the time. Some lots are just better than others. This is one reason there are several makers at the top of the list year after year.
