Many of today’s gun-makers started out in a different career path, but soon found a way to mix their expertise with their true passion: guns. David Moore, the owner of Spider Firearms, was born into a family of mechanics and soon found himself working on cars and drag racers.

But then he was able to shoot a .50 BMG rifle, and he started wondering if it was possible to create a bolt action with an AR-15-type upper in the massive chambering. He eventually ended up with the single-shot Ferret50, which author Jay Langston got his hands on for the upcoming November 2013 issue of Tactical Weapons. According to Langston, “The barrel is a stainless steel Lothar Walther Supermatch measuring 34.75 inches in length. The barrel’s 1.3- to 1.45-inch diameter allows 0.4 to 0.47 inches of steel around the half-inch bore, which provides plenty of strength, weight to absorb recoil and mass to dissipate heat. Capping the barrel is a four-vent muzzle brake that does an amazing job. By my calculations, it cuts recoil and muzzle rise by approximately 60 percent.”
