Helanbak’s masterpiece of OEM machining.

Helanbak’s HB15 Rifle AR15 platform comes completely assembled, featuring Helanbak’s complete billet upper and complete billet lower. Helanbak’s HB15 AR15 platforms are chambered in 5.56 NATO and built around a 16" barrel with a 1/7 twist rate. These rifles use a Mid-Length gas system, an A2 Bird Cage Flash Hider, and Helanbak’s 15" M-LOK Handguard to deliver a premium and precise OEM firearm. The free-floating 15" M-LOK Handguard features a slim, flush profile that offers increased ergonomics, maximum airflow, and modularity while continuing to provide the utmost strength and durability. The handguard provides a Picatinny rail along the top which allows room for sights, optics, and accessories. A proprietary key between the HB15 handguard and billet upper allows for a completely flush, sleek design. Helanbak’s HB15 AR15 platform is also available for special orders, allowing increased customization options for caliber and barrel length.
