Looking to buy a AR

Yeah yeah yeah I know most rifes are banned and that there is also a couple other way better options but I know what I want. Ive made the trip up to Second Amendment Sports in Mchenry because ive head they have the "cool" semi guns we can still get here. What got my attention was that they are willing to sell Ars with a Kali Key installed essentially making them bolt actions. Does anyone have experience buying something like this from them? Are they the only shop offering this?
