About this product

The F-1 Firearms UDR-15 Style 2 Chassis provides a foundation for a custom AR build. This chassis includes the UDR-15 3G Style 2 universal receiver set and the C7K Contoured Handguard. The receiver set features a new skeletonized design and a scalloped MIL-SPEC 1913 Picatinny rail. It is made from 7075-T6 billet aluminum.

The receiver set has an oversized trigger guard and a 60-degree beveled magwell. Front and rear takedown pins are included and installed. Screws are provided for the bolt catch, receiver tensioning, takedown pin detent, and trigger adjustment.

The C7K Contoured Handguard is designed with a quick placement grip area. It has a 1.65-inch inside diameter, which can accommodate most major suppressors within the rail. This handguard is a one-piece free-float design made from 7075-T6 aluminum. It includes an aluminum barrel nut and mounting hardware, along with an anti-rotation mounting system. The handguard features full-length Picatinny rails and Keymod side and bottom rail mounts. It has a Type III Class 2 hard coat anodized finish and a scalloped top rail.
