This is Umarex latest release in the T4E (Train 4 Engagement) range, announced at the March 2021 IWA Press Event.

The HDX, is an evolution of the well established HDS T4E range, and uses many of the same ideas, but with more features and adaptability.

This pump-action, Co2 powered shotgun (uses 2x 12g CO2 bulbs) can be loaded with up to 16 .68 calibre rounds and does not release the Co2 into the weapon until the system is punctured at the button on the stock, meaning it will be at full pressure on release.

The weapon features a sling point at the rear and M-LOK style rail fittings at the font. There is also RIS rail on the top surface for mounting additional sights, torches etc, and a small RIS section on the front underside, for mounting such accessories as lasers and tourches !
