Adcor Defense recently announced that they will be manufacturing a gas impingement version of their Brown Enhanced Automatic Rifle (AKA, B.E.A.R) rifle as opposed to a piston like their earlier models had. The B.E.A.R GI also features a ambidextrous forward charging handle and a Magpul MOE stock and FN made barrel. Adcor has yet to release pricing info as of yet.
