The Big Trick™ will serve you well in any situation, but it was intentionally designed for one specific purpose — to allow comfortable and discreet carry of longer guns, such as a full-scale folding sniper rifle. Low-profile magnetic closures on both sides of the pack offer quick access to your handgun while the expandable bottom compartment increases overall volume and lengthens the scabbard, allowing you to customize the pack for load size and weapon length. Expandable to 31.5" internal length.
