WTB KAC CQB 11.5 upper (3.1 rails)

[Zzzake]

Hello,

Looking to buy a KAC 11.5in upper, one with the 3.1 rails. I am in California it will be used for a pistol build. Hopefully it is in good condition with all the original parts, buffer, panels and such.

Also if anyone know where I can buy one new, please let me know.

Thanks everyone!
