F-1 Firearms Style 1 UDR Series Chassis
About this product
The F-1 Firearms Style 1 UDR Series Chassis offers a modern interpretation of the MIL-SPEC M16 platform. It is designed for minimal weight without compromising rigidity or appearance. Non-essential material has been removed, providing a streamlined foundation for custom builds. Each chassis is hand-finished and matched to ensure consistent quality.
These sets are compatible with MIL-SPEC patterned parts and Magpul magazines. They are machined from 7075-T6 billet aluminum. Unnecessary material is milled out to achieve the lightest reliable configuration. Features include an oversized trigger guard and a 60-degree beveled magwell. Front and rear takedown pins are included and installed. Screws for the bolt catch, receiver tensioning, takedown pin detent, and trigger adjustment are also provided. Black versions receive a Type III Class 2 hard anodized finish, while color versions are Type II hard anodized.
The F-1 Firearms C7K Contoured Handguard, included in this chassis, features a quick-placement grip area for improved repeatability and comfort. Its internal diameter is designed to accommodate most major suppressors within the rail. This handguard is constructed from 7075-T6 aluminum and utilizes a one-piece free-float design. It includes an aluminum barrel nut and mounting hardware, along with an anti-rotation mounting system. Full-length Picatinny rails are present, and the handguard is finished with Type III Class 2 hard coat anodizing.
