Ambidextrous controls with top of the heap if not best quality control out in the market, comes with an awesome trigger that sort of resembles the standard AR trigger but brings it to a whole new level. Not like a gieselle trigger(I own one two) but exactly what i would want in a combat trigger, if that makes sense.
Knights just seems to have the spirit of Eugene stoner still in the their AR line, sounds hoaky now that i'm writing this but it's just the feeling i get when handling and firing their rifles.
That being said "a lower is a lower".........
I just believe in supporting a company like that, which is so dedicated to producing Top of the line weapons for decades on end. Plus they shoot more and collect the data than most if not all AR companies out there these days..KevinB has said that and I know from other sources this appears to be true. They don't BS much compared to most other companies, and they don't stretch things that much.
So I'm a loyal KAC customer
