AR-15 Kali Key ERGO Bolt-Action System (B.A.S.)+ BCG Bundle


AR-15 Kali Key ERGO B.A.S. + BCG = Bundle and Save!


The only solution of its kind on the market:

  • This bundle comes complete with BCG (Black Nitride with MPI 5.56 Bolt) and Kali Key Bolt-Action System (B.A.S.), which includes Kali Key Ergo B.A.S. charging handle, Kali Key B.A.S. gas key, and two mounting screws.
  • Keep your rifle in “assault weapon” jurisdictions; build your ideal hunting rifle; build the quietest suppressed rifle; benefit long-range precision shooting.
  • As quick and easy as swapping out your BCG.
  • No removal of the gas system, no milling, and no custom modifications necessary – a TRUE DROP-IN SOLUTION
  • Simply screw on the Kali Key B.A.S. on the included BCG, and you’re good to go.
  • Convert any mil-spec, direct impingement (does not work with piston systems) AR-15 into a straight-pull bolt-action rifle.
  • Because a bolt-action is not an “assault weapon.”

NOTE: The AR-15 Kali Key will work on MIL-SPEC DIRECT IMPINGEMENT AR-15 rifles only. Please verify your AR-15 rifle is mil-spec and direct impingement BEFORE purchasing.

Drop in the Kali Key and stay Future Ready!

  1. Mario

    I have both the AR 15 and AR10 Kali Keys. This is a quality product and both keys worked flawlessly with my AR uppers. For my .308 upper I have the key that works with my Aero Upper. Make sure your upper works with the proper key for you .308 because the key will not fit your Aero upper unless you get the correct one. Kali just started making these and I was happy they did. This system replacing your regular BCG so that it’s basically a bolt action rifle. In states like California this is a good way to shoot your rifle without having to put fin grips or a stock you may not like. Its easy to swap out the semi auto BCG and install the Kali key BCG. Takes less than 30 seconds. Range time was great . I had no trouble getting used to using it . This company is first rate. I damaged my key because I dropped it and they immediately replaced it . Their customer service is outstanding. If you live in states were they are restricting your use of the AR this system is a must! I highly recommend the kali key!

    For me it was not to become State compliant, rather I am getting my grandchild into hunting. I like the AR platform; however I always felt semi-automatic was too much for the younger generation starting out; therefore, the Kali-Key was the perfect Idea for my grandchild to learn hunting with an AR Platform, but not semi-automatic.
    Thanks guys for this great Idea.
    Also it works on the left hand platform

    I live in NYS and can no longer buy Semi auto rifles without having a license since September 2022. I am fan of the AR platform and was only able to acquire ONE semi auto AR15 during that time. Since then the ONLY way to buy a rifle here on NYS is to buy either a Shotgun(surprisingly semi auto is allowed) or a bolt action rifle. So I found that we are still allowed to buy stripped lowers and build from there!!!!….. I know have a few AEROPRECISION AR10s and AR15s in different barrel lengths WITH ALL THE FEATURES because they are BOLT ACTION!!…. THANK YOU GUYS AT KALIKEY.COM!!!

    This innovation is a game changer so many situations. I needed a Kali Key in order to handle a transaction that was urgent. Called the company and the owner got back to me immediately and set me up so that I could come by and grab what I needed. He went out of his way to help in a way that only someone who cares about their customers would. I’ve run my own business for 13 years and I can confidently say these guys are the real deal and will stand behind their products and their customers. Appreciate you guys so much. Thank you.
