RE: Knight
I agree with cayugad............................my Knight USAK has been an excellent rifle for me - Shoots so good I've never had a desire to look for a "better" gun.
One thing about Knights - If you want to shoot super light, superfast bullets.....................don't go with the Knight. Due to their bore construction, Knights tend to get their best accuracy with heavier bullets (300gr & up) not pushed at outrageous speeds.
For instance, 80gr of 777 with 300gr sabots or 90gr of 777 with 350gr sabots can consistently cut 1" groups for me.........................while I was lucky to hit paper with 240gr sabots.
