.22lr AR-15 style rifle?

I am looking for a starting rifle, styled after an AR-15 and would appreciate suggestions. I am looking for a rifle chambered in .22lr, CA legal, and with good durability.
Update: To August: the reason that I want a .22lr is because I am only 16 years old. My parents agreed to let me own a rifle (even though I can't buy it). The .22 ammo is very cheep and will help me home my skills so that when I get a .556 AR-15 I will already be familiar with layout, cleaning, and function of the gun.
