sub 2000, Just right carbine.....
TNW ASR, CX4 and SUB 2000 were the contenders when I was making the choice. Bought the ASR because it felt sooo nice in my hands (wanted something different than everyone else as well), my buddy bought a SUB 2000 gen 2, and so far it appears to be a really great gun. If I sold my ASR, id definitely buy the CX4, the CX4 seems a little more compact, better reliability and has bolt hold open and release button(under rated feature). People tend to think there ugly though, and I personally found it felt fat/bulky in my hands.
