AB Biller Power Heads

These A.B. Biller designed and precision-engineered Power Head units are the most advanced and reliable products of its kind available.  The .38, .357 as well as the .44 caliber Power Heads are manufactured of high-grade stainless steel with newly designed firing mechanism and safety.  Power Heads are available with 6mm and 5/16″ thread.  They have been designed and manufactured according to the regulations set forth under the NATIONAL FIREARMS ACT.

FEDERAL LAW REQUIRES that the firing pin be 26″ long.  Any Power Head (fish popper) NOT CONFORMING is considered CONTRABAND and is subject to confiscation by the Bureau of Alcohol, Tobacco and Firearms, U.S. Treasury Department — BATF.

AB Biller Power Heads
H 44 - Power Head, .44 caliber
H 38 - Power Head, .38 caliber
H 357 - Power Head, .357 caliber
All A.B. Biller Power Heads come with a stainless steel cable
attaching the barrel to the shaft to prevent the lost
of the barrel while re-loading underwater.

OPERATIONS: The A.B. Biller Power Head has been designed for use and protection underwater.  The device is not classified as a firearm but must be treated as such.

The knurled safety nut must be tightened against the Power Head body at all times and only loosened by three turns immediately before use.  To load the Power Head the barrel must be unscrewed from the body and the barrel replaced finger tight.  During loading and unloading special attention must be paid to insure that the safety nut is tight.

NOTE: It is recommended that the Power Head be used with BLANKS, since it is not the projectile, but the concussion of the explosion that kills the fish.

MAINTENANCE: The A.B. Biller Power Head is manufactured from high-grade stainless steel and requires little maintenance.  After each use the Power Head should be rinsed with fresh water and lubricated with a very small amount of silicone.
