Description

A modern, complete Micro Conversion Kit (MCK) chassis manufactured by Command Arms Accessories (CAA USA). This accessory is designed to convert compatible handguns (such as various Glock models, according to manufacturer specifications) into a stabilized platform, offering enhanced accuracy and handling. The chassis is constructed primarily of durable polymer in a two-tone finish, featuring a tan/Flat Dark Earth (FDE) body and black accent components. Key features include a full-length top Picatinny rail for mounting optics and accessories, and an attached black polymer folding or collapsible brace/stock assembly, complete with a webbing strap. The unit is distinctly marked with the MCK winged logo and the text “MADE IN THE U.S.A.” The kit includes the main chassis unit, one discrete black polymer accessory component (likely a spare magazine carrier or thumb rest), and the original paper “OWNER’S MANUAL” (Version 1.0). The entire kit is housed in its original white corrugated cardboard box, which is branded “CAA USA” and “MICRO CONVERSION KIT.” Text on the packaging emphasizes that the product is “100% MADE IN THE USA.” This item falls under the category of firearm accessories, and prospective buyers should be aware that local, state, and federal regulations regarding stabilizing braces and conversion kits may apply.
