    I can’t believe people pay that much for AR pattern rifles. You could build the exact same gun with the exact same accessories and performance for less than 1/3 of their asking price. If HK’s mantra is “because you suck, and we hate you,” KAC’s should be “Because We Can Get Away With It, Suckers!”

    Please, price out the rifle that would be equal to this, and of this quality please… It includes front and rear BUIS, BCG and charging handle. It comes very close at $1300 dollars to most others in that quality range… However, I do believe you are also paying in part for the name sake.

    What other company makes a completely ambidextrous lower for the AR? None that I’m aware of.

Combine those two proprietary technologies with a CHF barrel (probably made by FN, like DD’s and BCM’s are) and the URX rail and I think it’s not a bad deal. Certainly not “just the same as…”
