The barrel is made from light, non-deformable anti-corrodal aluminium. 

The inclination of the handgrip is designed for perfect firing and for quick, instinctive aiming; this is covered in rubbersoft. 

The trigger system is very gentle and progressive, and is fitted with a safety catch.

A strong ring for the line comes out of the bottom of the handgrip, and at the front there are 2 line releasing devices, the dovetail trigger for the reel and a somewhat advanced spear-rail saddle.

The muzzle has 13 mm standard bands complete with simple arched wishbones with a right ratio between loading ease and forward thrust.

The muzzle is set for possible use of a second circular band. 

The 6 mm diameter shaft comes with a single wing and two weapon notches.

Sioux comes in the following lengths:  50 (barrel 45 cm, 60 (barrel 55 cm), 75 cm
