RUN THE FUCK AWAY FROM JOE KEN
Joe Ken is notorious for selling items on their website that they don't actually have. When they've collected enough money from individual sales only THEN do they place an order with their distributor. The wholetime that you're calling to check the status of your order it's always "uh... we'll be shipping next Tuesday" even though that's the same thing they've told you for the last three weeks.
I talk from personal experience; I ordered a complete AR from them right after the AWB ended. It took damn close to two months of thier promises before I finally got it, and then it was a post-ban upper with a fake/non-functional flash suppressor pressed on. I had to threaten to get my credit card company involved and call their better business burea/local police before they agreed to swap out my upper for a no-ban version.
Oh and they wanted me to pay out of pocket to mail my neutered upper back to them, and then pay the shipping costs to have the no-ban upper shipped back to me (which they specifically stated would be on the rifle when I first ordered it).
There are far more reputable companies to deal with out there. For the few bucks you might save with them you'd be way better off saving yourself the hassle of dealing with their bullshit.
