Adderini is the compact 3D printed repeating slingbow/crossbow pistol with integrated quiver (magazine) for 6 arrows (bolts). The pistol is powered by TheraBand Gold rubber or standard pistol
crossbow limbs and has integrated ergonomic grip and cocking lever with about 4 times lever effect. The pistol is compatible with standard 160-163 mm long bolts (for pistol crossbows). It can be loaded manually or automatically with additional ammo clips (same as Sliding Legolini), after pivoting the magazine spring lever. A standard open sight system is used for aiming. Pistol is also equipped with 2 picatinny rails for laser sight/flashlight/front handle and red dot sight or short scope.

Parameters:

• Total length: 345 mm (520 mm with stock)
• Height: 182 mm
• Mass weight (pistol only): about 0,6 kg
• Mass weight (with 6 bolts, red dot sight, laser sight, stock): about 0,9 kg

The slingbow version:

• Width: 100 mm (60 mm with folded slingshot arms)
• Arrow energy: up to 11 J (with Steambow Bodkin 10.5 g bolts and TheraBand Gold bands 60 mm per side - about 55-60 lbs)

The crossbow limbs version:

• Width: 440 mm (EK Archery Cobra 80 lbs limbs)
• Arrow energy: up to 10,5 J (with Steambow Bodkin 10.5 g bolts and EK Archery Cobra 80 lbs limbs - in real terms about 50 lbs)
