Behind the brand

AB Biller is a trusted name in the spearfishing community, and manufacture their spearguns right here in the USA. Having created a number of spearguns for both state and national spearfishing champs, it’s clear they know their stuff when it comes to designing weapons that are comfortable and easy to use.

My first gun wasn’t an AB Biller, but once I got my hands on one I could see why people rave about this brand, and I’ve been an avid supporter ever since.

AB Biller Spearguns

AB Biller has a lot to offer when it comes to spearguns. They classify their different spearguns primarily on the materials used to construct the barrel, using either Teak, Paduak or Mahogany, and there’s even a Stainless Steel model which is that good it actually topped our buyers guide to the best spearguns in the market. They’ve also produced two special spearguns. The AB Biller LTD is a handcrafted series catering to large guns for deep water use, while their Floridian models were crafted based on real customer feedback.

Of them all, the AB Biller Mahogany speargun is one of my favorites. It’s also one of the oldest guns I own, I’ve got an old model that’s held up well going on 10 years now, and it performs just as good as the new one off the shelf I tried over the weekend.

The AB Biller Mahogany Speargun

When constructing anything for the ocean, Mahogany is a staple that’s been used for hundreds of years because it’s just so damn strong. Crafted from a single piece of mahogany, the wood’s also been treated with three coats of polyurethane to keep the water out, and sealed with linseed oil.

The end result is a beautiful gun, though you really can’t go wrong with any of their wood models, teak, paduak and mahogany all make for a very visually aesthetic speargun. But that’s not the only reason to use wood. The solid barrel reduces a whopping 80 percent of the shaft noise, helps to absorb recoil in every shot, and gives the gun a natural neutral buoyancy underwater.


The cost of the AB Biller Mahogany Speargun will differ based on the length of the gun you want to buy. The speargun I’m reviewing today is their 48 inch (122cm) model.

The handle

The hard plastic handle has a nice section that protects your fingers, however I’d prefer if the grip was a little more angled. It’s missing that nice relaxed position you get with many pistol-grip spearguns, in my opinion the handle is a little too square. But maybe that’s just me.

The trigger

According to AB Biller the stainless steel trigger mechanism is unsurpassed in reliability and smooth action. In reality I think it’s a decent setup, but I’d be wary about loading too much pressure on this trigger (think like three 20mm bands) as it’s not been designed for the massive amounts of force you’d expect on a big gun and I’ve heard that it can fail when you overload it too much. I tested this though and in my dive I couldn’t get it to fail, so maybe yours will hold up fine.

The shaft

Off the shelf the AB Biller Mahogany speargun comes with a stainless still “spring” shaft that’s 5/16″ in diameter, otherwise known as 8mm. After being heat treated to Rockwell 44C in a technique developed by the US Navy, you get a unique combination of spring tension and hardness in the AB Biller shafts.

The barrel

Hand carved from a single piece of mahogany, there’s a groove running along the top to boost the accuracy of your shots and absorb the noise the speargun makes. What’s particularly nice is the neutral buoyancy of the wood, as it makes it easy to track your fish.

The muzzle

The muzzle on the AB Biller Mahogany speargun is hard plastic, with an open design that allows you to aim straight down the spear to your target fish.

How it actually feels to use

Taking the speargun out on the boat I loved the rich brown shine the new mahogany had, compared to my older gun I silently wished I had given old faithful a bit of an oil rubdown before heading out.

The best thing about wooden spearguns is their buoyancy. They’ll sit comfortably in your hand while you swim around aiming at everything, and the wood really does absorb most of the recoil and noise as you take a shot. Just don’t forget to upgrade the bands. The ones it comes with are a little lacking in power, which is important if you’re out targeting bigger fish.

I found the channel running down the barrel of the gun to really help each shot fly true, and I landed one of the biggest kingfish of my diving career using this gun about a half hour into our first dive of the day. Not bad for the first time I’ve taken it in the water. Plus it really upset my mate as I borrowed this gun from him for this review.

Reloading is simple as the shaft slides right down the channel, and it’s got a similar rubber butt to their stainless steel model which really is quite comfortable. All up, I had a great day and I was a tad reluctant to give this speargun back once we were done.

The downsides

When I start looking at bigger spearguns what matters most is the range. Off the shelf, the 48″ model advertises a 12 foot range, but feedback from a few people mentioned it runs out of steam this far away and if you don’t swap out the bands it’ll “bounce” off the bigger fish.

This particular speargun was a friends I borrowed for a test run, and he’d swapped out the bands for two 20mm bands (we did add a third to see if we could get the trigger to fail but it held out strong). He’d also replaced the shooting line with mono to reduce the drag, and if you want even more power you could swap out the shaft for a thinner version. I’ve not yet experimented with this yet so let me get back to you on this one.

The results

For the price you’re going to struggle finding a better quality wooden speargun. It’s easy to reload and one of the best features is the gun will float next to you on the surface while you’re fiddling around with it.

If you take care of it with a little oil now and again the wood will hold up great for years, as it’s not the cheapest speargun on the market but in my book it’s worth every penny. When you’re looking for an all-round speargun that’s going to help you catch a bunch of fish, the AB Biller Mahogany speargun is a smart choice.
