If you mean the Umarex double-barrel marker, the model is HDS68/TS68—not HDR68/TR68. HDR68/TR68 identifies the revolver. That distinction comes first when choosing a Z-RAM holder: the HDS holder shown here holds loose projectiles, while the separate Dual Drum Magazine Holder is for the Tec9 body kit on HDR68/TR68.
One letter changes the platform
HDS68 and TS68 are two regional names for the same double-barrel platform. HDR68 and TR68 are the corresponding names for the revolver platform. They form two separate model pairs. The shared .68 caliber does not make an accessory for one pair fit the other.
When searching for a holder for the double-barrel marker, use HDS68 or TS68. An HDR68 result can instead lead to revolver accessories. Read the complete model and accessory name together: “ammo holder” and “drum magazine holder” describe different objects, even when the pictures show accessories alongside a .68 marker.
The HDS68/TS68 holder stores loose projectiles
The current Z-RAM HDS68/TS68 offer below is the black, high-strength polymer holder listed with space for 16 round balls. It is external storage for individual projectiles. That number describes the holder’s storage positions, not the firing capacity of the double-barrel marker.
The offer supplies one holder without ammunition. Its handling instruction is important: do not transport the marker with projectiles in the holder. If HDS68/TS68 is your marker, this is the relevant product of the two shown here; the second card explains a different holder you may encounter while browsing.
The Tec9 dual holder stores spare drums instead
The Z-RAM Dual Drum Magazine Holder is designed to hold two separate drum magazines. Its specified host is the Z-RAM Tec9 body kit for HDR68/TR68. Tec9 is a Z-RAM body-kit product line, not another name for the HDS68 double-barrel marker.
The exact fit restriction matters: this dual holder is only for that HDR68/TR68 Tec9 body kit. It is not an HDS68/TS68 accessory, does not cover the HDR50/TR50 Tec9 version, and is not a universal holder for a bare HDR68/TR68. The model and the required body kit are both part of its product identity.
Match the marker, then the object being held
For the double-barrel HDS68/TS68, look at the holder for loose projectiles. For an HDR68/TR68 already equipped with the matching Tec9 body kit, the dual-drum product concerns spare drum magazines. These are not two sizes of the same accessory or two purchases needed for one setup. Keeping the host and the held object separate resolves the name confusion before it becomes the wrong order.
For the body kit required by that dual holder, the Tec9 guide for HDR68/TR68 explains the .68 kit and the difference between its Full and Compact versions.
