Rellim Arms

What Rellim Arms does

Rellim Arms, LLC is a privately held, founder-operated firearms manufacturer founded in 2014 by Mike Miller in Wichita, Kansas. The company designs, machines, and assembles a portfolio of AR-platform pistols, carbines, and components built around its proprietary AMP (All Missions Possible) Weapons System — a takedown architecture that allows users to remove the barrel and stock or brace in seconds and switch between calibers (5.56/.223, 300BLK, and 9mm) and barrel lengths on a single lower. Proprietary parts are CNC machined from 7075 T6 aluminum with Mil-Spec Type III Class 2 Hardcoat anodizing, and the company holds patent-pending status on its AMP Takedown System, stock adapter, and QD barrel nut assembly.

The product portfolio spans complete firearms (AMP Takedown 5.56/300BLK at $1,895, AMP Takedown 9mm at $1,745, AMP Takedown Ammo Can, and the Folder Kit), supporting components (upper receiver kits, barrel kits, stock adapters at $220), and finishing services (in-house custom Cerakote coating and laser engraving added in 2022). Strategic supply and integration partners include Ballistic Advantage (barrels), Rainier Arms (M-LOK rails, ambidextrous charging handles, and third-party distribution), SB Tactical (SBA3 brace), Hexmag (30-round magazines), Law Tactical (folder), and Gun Rodeo (e-commerce platform), with magazine compatibility for Glock 17-pattern 9mm magazines.

The business operates a hybrid go-to-market: direct-to-consumer e-commerce through rellimarms.com (powered by Gun Rodeo), a national stocking dealer network with active dealer recruitment, gun-show sales of Cerakote demo guns, and wholesale distribution through Rainier Arms. All firearms are FFL-transfer-only, shipped to valid Federal Firearms License holders. The company is served by 1–10 employees, has never disclosed institutional funding, and has reported no revenue; pricing is unit-based with no recurring contracts. End customers are individual firearms enthusiasts, tactical operators, and AR-15 customizers seeking modular, multi-caliber platforms, while channel customers include FFL dealers seeking differentiated inventory.
