QUADSHOT DEFENDER

about

A four-shot disposable smoothbore weapon which uses improvised ammunition. Both a printed barrel and a barrel sleeved with steel tubing inserts can be used. Each striker is pulled back and released to fire each barrel.

 

#### Materials:

              - M5 x 120mm bolt (or length of studding)
              - M5 nut
              - Compression spring, 75mm long x 12-15mm wide, 1mm wire
              
              Optional:

              - 10mm x 2mm dia Mild Steel Seamless Tube
              - 1/2" long Self-tapping plastic screw or glue (to attach grip)
                


#### Ammunition::

An 8mm PAK blank is modified by drilling through the plastic plug using a 6mm bit. A 6mm Stainless Steel Ball Bearing is then seated into the plug and sealed with wax. At close range the improvised round is comparable to .25 ACP. Powder can be reduced or increased in increments. Powder from Hilti or Ramset nail gun blanks can also be substituted. 8mm PAK blanks are significantly thicker walled than regular cartridges and are thus well suited for these applications. Solid 'Piledriver' air gun pellets are also an option.
