The A.B. Biller Speargun, built in the U.S.A. and in use all over the world, has proven itself as the foremost production speargun on today's market.  The stainless steel trigger mechanism is unsurpassed in reliability and smooth action.  The high grade grooved mahogany, teak, or padauk barrel provides pinpoint accuracy, easy underwater maneuverability due to its neutral buoyancy and absorbs 80% of the firing noise a metal gun will create.  The importance of noise elimination when firing a speargun under water is a well-known fact to most experienced and successful spearfisherman.

All A.B. Biller spearguns are provided with a stainless spring steel shaft 5/16″ diameter, manufactured from a special alloy originally developed for the U.S. Navy.  Heat-treated to Rockwell 44C, these shafts produce a unique combination of hardness and spring tension. Two 9/16″ O.D. natural rubber slings with special stainless steel swiveling wishbone and a hardened stainless spring steel double barb swivel tip are standard with A.B. Biller guns.

The A.B. Biller Company manufactures our spearguns in several variations and has provided the guns for many U.S. National and State Spearfishing Champions.

No matter how superior a speargun may be, the person using it remains the largest factor in safe and successful spearfishing.  A weapon as it is should be used with care, respect for the environment and with sportsmanship.

All A.B. Biller Spearguns come with three groove shafts for gun size 42″ and longer.

Most Popular -- The A.B. Biller Mahogany series is our best seller (best price).  And, although the A.B. Biller Mahogany is available in 7 sizes, we sell more of the shorter spearguns due to the conditions here in Northern California (lower visibility and dense kelp).

AB Biller Mahogany

Mahogany wood has a high strength factor compared to its weight and is very durable.  It is widely used in marine applications.  All A.B.Biller spearguns are hand made.  The mahogany wood receives 3 coats of polyurethane to protect it from environmental influences.
