just throwing this out...build one...put the parts on that you want. it may not be a smith, but it can be just as good. i finished building my first ar just before thanks giving. i have quality parts in it. a chrome lined barrel with a 1:7 twist. a 13" hand guard over a low profile gas block. a very nice stock that i like better than the magpul that i put on my 15-22. etc etc...all for less than $800.
i had never even held an AR before deciding to build this.
