HB10

Machined In-House

Cut on Our Own CNC Floor

The HB10 is a DPMS-style AR10 — chambered in calibers built on the .308 Winchester and Creedmoor parent cases. Every upper and lower receiver is cut on our own CNC floor in Columbia, Mississippi.

HB10

Built In-House

No Shortcuts on the Receiver Set

Precision gas-operated, running a mid-length gas system off a low-profile 4140 steel gas block. The free-floating 15″ M-LOK handguard runs slim and flush — better grip, better airflow — with a full-length Picatinny top rail for sights, optics, and accessories.

HB10

Proofed Before It Ships

Finished Under One Roof

Available in 16″, 18″, 20″, and 24″ barrel lengths, finished in Cerakote™ Magpul® Black as standard, with flip-up sights included. Other Cerakote™ colors, such as Magpul® FDE or OD Green to match Magpul furniture, are available and priced per order. Like everything that carries the Helanbak name, the HB10 is machined, finished, and proofed under one roof before it leaves Columbia.

Will it fit my standard parts? The billet upper and lower are machined as a matched set. For the best fit, run them together rather than mixing with a forged receiver.
