About Shockwave Technologies
Shockwave Technologies is a veteran-owned American maker of firearm furniture, owned by Marty Ewer, best known for two products that shaped the market for short-barreled, non-NFA firearms. The first was the Blade, a slim, glass-reinforced polymer pistol stabilizer for AR-pattern pistols that weighed about 5 ounces and sold for around $50 when reviewed in early 2015. In April 2015 KAK Industry of Oxnard, California, then led by president Kurt Kosman, announced exclusive distribution rights to the Blade line and introduced a matching 12-position KAK Shockwave buffer tube.
The second was the Raptor bird’s-head pistol grip. In 2017 Mossberg introduced the 590 Shockwave, a 14 3/8-inch-barrel, 12-gauge pump-action firearm fitted with the Raptor grip and sold as a non-NFA firearm, a configuration later copied across the industry. For gun owners, Shockwave products sit at the center of the long-running debate over how federal law classifies braced pistols and short “firearms” that are not legally shotguns. ATF’s 2023 pistol brace rule was vacated by a federal court in June 2024, and the Justice Department dropped its appeal in 2025.
