Bulky. Sights are hideous. I would buy a CX4 and have money leftover. The ZRX can looks cool in a video game kind of way. And the trigger is like... I can't say that here. And the gun does not fit me. I'm lanky and just can't get there from here.
Is the ZRX pretty quiet compared to traditional cans? Been keeping my eye on them, didn't know they were in customer's hands already. I hear they are working on a 556 version as well.
