AR-15 Kali Key LO-PRO


In stock




The Kali Key Lo-Pro is our new sleek, minimalist design. We designed it for those who prefer a small footprint for transportation purposes and a more traditional, “tactical” look and feel. The user experience will resemble using a mil-spec charging handle to cycle your rifle as a bolt-action.

The only solution of its kind on the market:

  • Bolt-Action System comes complete with Kali Key AR-15 Lo-Pro B.A.S. charging handle, Kali Key B.A.S. gas key, and two mounting screws.
    This option does not come with a BCG. You will need to install the Kali Key bolt-action system on your own BCG or buy our high-quality, extremely cost- effective Bolt-Action System and BCG bundle here.
  • 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 replace the factory gas key and charging handle on any Mil-Spec bolt carrier group with the Kali Key B.A.S., 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 Lo-Pro 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!
