Another vote for building your own here!
I was able to build EXACTLY what I wanted with what I would call higher end parts for about the price of a base off the shelf AR.
Aero Precision lower from AIM Surplus ( Aero Precision is probably the major 'maker' of AR lowers, they make lowers for a LOT of companies )
Daniel Defense lower parts kit ( GREAT quality parts, Great service grade trigger, fair price )
Magpul MOE furniture kit ( grip, stock, buffer tube, buffer, buffer spring, and a forearm I didn't use )
Ambi Safety ( must have in my opinion )
Bravo Company 'Blem' upper ( came with the dust cover and forward assist ), M4 feed ramps
Bravo Company barrel, 14.5", 1 in 7, mid length gas system, Nato chamber, M4 feed ramps
Yankee Hill Machine low profile gas block and stainless gas tube
Yankee Hill Machine rifle length full floating forarm
Bravo Company bolt group
Bravo Company gunfighter charging handle
I pinned and welded the muzzle device myself to make it all legal.
All in all a GREAT rifle for the money and far more capable than I am most of the time....
Build your own....its worth it!
