This is whatcha want...
Since purchasing this I haven't seen any others with the included "Z" mount, but if you can find one, GET IT! You don't want anything other than an aimpoint. They are the end all choice for carry handle optics (short of blowing a grand on an ACOG, but on a non-flattop I just can't see it being worth it...on a full 20+ inches, different story)
Also, if the list price is 400 dollars, try your hardest to get it for 3 otd...I did.
I also just noticed that you were asking for a variety, but you don't need a variety. Aimpoint Aimpoint Aimpoint! Anything less just won't be worth the wasted ammo.
