Wow! That didnt take very long. I see we have some AR snobs in here now. I for one have shot some excellent examples of the AR platform that meet the "junk" definition above. Furthermore I Have been building using "junk" parts for years now and I have to say that DPMS in particular has routinely performed in an average way or better every time. If you want to parrot what the idiots say on AR15.com go ahead. It seems that every forum has its share of sheeple.
I'm happy for you, and I'm sure you'll have no problems either.
You said it well.........."I have to say that DPMS in particular has routinely performed in an average way or better every time."
If all you're looking for is "average", then average is all you can hope for. I hope all your goals in life aint average.......but if they are, you're sure to hit 'em!
