A Dedicated 9mm Platform.
The Hemlock isn't an AR-15 forced to shoot 9mm; it's a dedicated Pistol Caliber Carbine designed from the ground up for the 9x19mm cartridge.
Precision machined in-house from solid blocks of aerospace-grade 7075-T6 Billet Aluminum. Our proprietary skeletonized lower receiver natively accepts Glock® style magazines and features a true low shelf geometry. The slick-side billet upper provides a streamlined profile ideal for close-quarters manipulation.
- Flared magwell for lightning-fast reloads.
- Integrated oversized trigger guard.
- Heavy-duty slick-side upper receiver.

Unrelenting Performance.
Leveraging a robust blowback operation system, the Hemlock delivers exceptional reliability across a wide range of 9mm ammunition. It is driven by our SIA 9mm Enhanced Bolt Carrier Group, engineered with increased mass to smooth out the recoil impulse and ensure consistent cycling. Available with your choice of rear or side charging configurations.
Unlike many PCCs on the market, the Hemlock features a highly reliable Last Round Bolt Hold Open (LRBHO) mechanism built directly into the lower receiver, ensuring familiar AR-style manual of arms.
Mission Configurable.
Whether you need an ultra-compact 4" setup for backpack carry or a 16" carbine for competition, the Hemlock adapts to your requirements.
Finished in world-class Cerakote (Armor Black, OD Green, FDE, or Custom) and outfitted with premium Hogue overmolded grips and stocks/braces. Every Hemlock is hand-assembled, test-fired, and backed by our commitment to zero-failure tolerance.
