Lets see,
Base gun: $1,000
Surefire Quadrail: ~$300
EoTech: ~$450
BUIS: $120
Hogue Grip: $25
Surefire: $300(?)
Total: $2,170
so its about the same as if you did your own build (assembly)
Would I get one? No.
But if I were looking for a RockRiverArms AR, and that exact line up of accessories- I would since it is factory assembled.
RR does make great AR's and it will cost you $2,200 to put a combo like this together, so I think it will have a fair amount of success
