AB Biller Mahogany Wood Speargun

AB Biller Mahogany Speargun: A Hand-Built American Band-Powered Speargun for Serious Spearfishers

The AB Biller Mahogany Speargun is a band-powered, wood-barrel speargun made entirely by hand in the United States.

If you are a recreational spearfisher who wants a proven, well-constructed gun rather than a budget import, this is the kind of equipment worth understanding properly before you buy.

The Barrel: Why Wood Matters

The barrel is the heart of what makes this gun different from most modern spearguns.

AB Biller uses high-grade grooved mahogany, finished with three coats of polyurethane to protect it from saltwater and sun. Mahogany is a dense, stable hardwood with a long history in marine use, and AB Biller points to two practical reasons for choosing it over metal or plastic.

First, the barrel is neutrally buoyant. That means it neither floats nor sinks in the water column, which makes the gun easier to aim and hold steady without fighting its weight or lift.

Second, wood absorbs significantly more firing noise than metal. AB Biller states the mahogany barrel absorbs roughly 80% of the noise a metal gun produces when fired. This is not a trivial point. Fish are highly sensitive to pressure waves and sound. A quieter shot gives you a real advantage, particularly on wary species or in clear, calm water where fish can detect disturbance from a distance.

The grooved barrel also acts as a rail, guiding the shaft along a consistent path and contributing to the accuracy the gun is known for.

Shaft and Slings

The shaft is 5/16 inch in diameter, made from a stainless spring steel alloy originally developed for the U.S. Navy and heat-treated to Rockwell 44C hardness. That combination of hardness and spring tension is what lets the shaft flex on impact and return straight rather than bending and staying bent, which is a common failure point on cheaper shafts.

Standard guns up to 36 inches come with two natural rubber slings, each 9/16 inch outer diameter, fitted with stainless-steel swiveling wishbones. The 42-inch and 48-inch guns come with three slings, which adds the pulling power needed to drive a longer, heavier shaft effectively.

The tip is a hardened stainless spring steel double-barb swivel rock point. The swivel design lets the shaft rotate after penetration, which makes it significantly harder for a fish to shake free. The reduced diameter of the tip also cuts drag in the water, helping the shaft travel straighter and faster.

Trigger and Safety

The trigger mechanism is machined from hardened stainless spring steel and housed in a nylon cartridge. Nylon dampens vibration and resists corrosion without adding weight, and the cartridge design keeps the mechanism clean and consistent.

The safety is redesigned and patented for one-handed operation, with a silent lock and unlock action. Silent matters here for the same reason a quiet shot does: any noise you make while preparing to shoot can put fish on alert. The safety also works in both right- and left-handed positions, so it is not going to limit you regardless of which hand you shoot with.

The muzzle, grip, and butt are rugged plastic, keeping the non-structural parts light and resistant to impact.

Choosing Your Length

The AB Biller Mahogany comes in five sizes. Shaft length determines how much reach and power you have; overall gun length tells you how much you are physically handling in the water.

As a general principle, shorter guns suit confined spaces: reef crevices, kelp, rocky structure where a long barrel becomes a liability. Longer guns give you more range and power in open water, or when targeting larger, faster fish that will not let you get close.

If you are hunting in mixed conditions, the 36-inch sits in a practical middle ground. If you are regularly working open water for bigger fish, the 42-inch or 48-inch with the third sling gives you noticeably more drive.

Who This Gun Is Built For

The AB Biller Mahogany is a production gun with a genuine track record. AB Biller notes it has been used by U.S. National and State Spearfishing Champions, and the design has been refined rather than reinvented over many years.

It suits a recreational spearfisher who wants reliable, well-made equipment and is willing to maintain a wood barrel properly. Three coats of polyurethane protect the mahogany, but like any wood in a marine environment, it rewards attention. If you rinse it, store it out of direct sun, and inspect the finish periodically, it will last.

If you are looking for a compact travel gun, the 24-inch or 32-inch versions are manageable. If you are an experienced hunter who prioritizes shot accuracy and noise reduction over the convenience of a carbon or aluminum barrel, the Mahogany is a strong choice at any length.

What this gun is not is a technical bluewater rig for very large pelagic fish. For that kind of hunting, pneumatic or roller guns purpose-built for power and extreme range are the more appropriate tools. The AB Biller is at its best in reef, coastal, and nearshore environments where its neutral buoyancy, quiet shot, and accurate rail system work in your favor.
