3D model description

The UMAREX HDS 68 defensive rifle uses a Co2 sparclette and can fire 2 .68 caliber rubber bullets (or paintball) with 16 Joules of power.

For this weapon, I have created 2 new special ammo (see my other ammo at the bottom of this page):


25 mm height and 2.84 gr weight

Composed of 3 elements: a base, a sleeve in which a small nail is threaded, and a collar (your choice: a full collar or a perforated collar).

Each sleeve accepts a flat head nail diameter of 1.4 or 1.6 or 1.8 or 2.0 or 2.2


  • The assembly will eventually require a drop of Superglue.

  • Each nail must be at least 30 mm long

  • To be used on a soft target (foam, polystyrene ...). By adding a laser on your HDS 68, you will turn it into a target shooting weapon!



Height assembled: 35 mm, weight: 2.55 gr, formed of 2 elements that fit together.

Be careful when inserting the ogive at the top of the base, the claws are very fragile!

Upon impact on a hard target, the claws will open into petals.


  • a box for .68 cal ammunition is available for free here :


  • and a display also free for this weapon:

(clamp the jaws on the trigger guard, see photo).




To be used exclusively for recreational shooting!

The use of this ammunition is much more dangerous to injure than the original rubber bullet!

Here in France, in case of injury to a possible attacker, you will risk criminal prosecution ...
