The HRT Modulus placard was designed to attach to our HRAC and RAC plate carriers or work in conjunction with Duraflex Buckle system. The Modulus placard comes standard with an elastic AR magazine insert but can be replaced with any of HRT’s inserts. The straps on the Modulus placard are height adjustable so you get the perfect length to match to HRT’s or others carriers. The strap attachment system comes standard with the swift clip style buckles, but can easily be replaced to G-Hook, Molle-T or many other placard mounting options on the market.
