An anti-ballistic barrier system with a top shield support, a bottom shield support, and an anti-ballistic shield. A first extendable connector may extend between the anti-ballistic shield and the top shield support. Similarly, a second extendable connector may extend between the anti-ballistic shield and the bottom shield support. A polyester shield cover may extend over the anti-ballistic shield. A top mounting bracket attaches the top shield support to a vertical structure and a bottom mounting bracket attaches the bottom shield support to the vertical structure. The anti-ballistic shield is movable between a retracted position in which the anti-ballistic shield is wrapped around the top shield support and the bottom shield support is detached from the bottom mounting bracket and an extended position in which a majority of the anti-ballistic shield is unwrapped from the top shield support and the bottom shield support is engaged with the bottom mounting bracket.
