Duostock Designs, Inc. launches its answer to the often encountered problem with the M4/CAR15 collapsible stock; how to establish consistent stock placement on the shooter's shoulder using the as-issued stock and it's lower point or tip? The Tactical Duostock solves this by using a lower surface that is placed on the upper chest/shoulder to allow a consistently upright head position without the need to constantly readjust the weapon. Ideal for ballistic vest users as the larger contact area of the angled lower surface is stabilized on the firmer surface of the vest. Weapon position on the shoulder is maintained at low ready position and the weapon can be lifted to eyes-on, sights-on target instantly, without fear of slippage or loss of contact.
