The HG-105 is a semi-auto gas-piston operated detachable magazine bullpup shotgun. It has a 12 Gauge 3” chamber with a 18.5” barrel. The bullpup configuration allows for a smaller overall length without a compromise in barrel length. This configuration results in a center/rear biased weight distribution, which reduces strain during long periods of use and increases transition speed in CQB and action shooting scenarios. The detachable magazine allows for easy and rapid reloading over conventional tube type systems. Magazine seating is straight insertion style, allowing for smooth and simplistic reloads. It features a monolithic top picatinny rail, height adjustable check rest, and a bottom picatinny rail. Upper receiver is constructed from aluminum while the lower is polymer. 4140 Steel Barrel with interchangeable chokes.

Comes with manual, one 5 round magazine, padded soft case, angled foregrip and detachable flip-up iron sights.
