What Tandemkross does

Tandemkross is a privately held aftermarket firearms parts manufacturer founded in 2012 and based in Weare, New Hampshire. The company designs, produces, and sells precision-machined upgrade components primarily for rimfire firearms platforms, with a heavy concentration on the Ruger 10/22 and Ruger Mark pistol series, and growing coverage of Taurus TX22, Smith & Wesson, CZ Scorpion, Walther, Sig Sauer, FN, KelTec, and Tippmann platforms. Its core technology is CNC machining of aerospace- and aircraft-grade aluminum, hardened tool steel, and stainless steel, with proprietary designs such as the Eagle's Talon positive-hook extractor, the Victory Trigger skeletonized flat-faced shoe, the Manticore/Manticore X integrated trigger-and-chassis assemblies, the DoubleKross dual-compartment magazine, and lightweight takedown barrels. All products are domestically manufactured and backed by a Lifetime guarantee.

The company's product portfolio spans small springs and follower buttons (under $15), mid-range aftermarket upgrades such as triggers, extractors, and magazine releases ($13-$55), premium drop-in assemblies like the Manticore and Manticore X ($300-$550), and fully assembled "TANDEMIZED" complete firearms (approximately $1,250). It also resells third-party accessories under the Gunsmither tools, Gun-Guide printed manuals, and Maglula loading-tool sub-brands. Pricing is uniformly one-time unit sales with no subscription component.

Tandemkross operates a direct-to-consumer e-commerce model on a BigCommerce storefront and a B2B dealer program serving firearms retailers, with international shipping to roughly 14 countries across North America, Europe, Oceania, South America, and Africa. The company is co-owned by Tom and Bryan, has between 11 and 50 employees, and shows no evidence of institutional investment, M&A activity, or public-market presence. Marketing is concentrated on organic social media (YouTube tutorials, Facebook, Instagram, Twitter), an installation-video library, and industry association affiliations with the NRA and NSSF.
