Stinger Billet Magazine

Stinger Billet 15-Round AICS Pattern Magazine

Crafted from rugged 7075-T6 aluminum, the Stinger 15-round AICS pattern magazine is engineered for precision and durability. It features the industry’s only multi-adjustable stainless steel latch, allowing fine-tuned control over heightbody width, and presentation angle.

The innovative latch system uses two set screws to adjust both the outward protrusion and angle relative to the magazine body, ensuring a custom fit and consistent feeding performance.

While optimized for use with our Stinger action, this magazine is also compatible with many 40X-style .22LR clone actions, thanks to its high degree of adjustability.

Weighing in at a solid 16 ounces unloaded, the Stinger magazine mimics the weight of a loaded centerfire mag, making it ideal for rimfire training setups that need to replicate centerfire balance and handling.

⚠️ State Restrictions:
Due to local regulations, we cannot ship this magazine to: California, Connecticut, Hawaii, Illinois, Maryland, Massachusetts, New York, New Jersey, Oregon, Rhode Island, Washington, or Washington D.C.

Hyve Chassis

Hyve Chassis – Engineered for Precision Competition Performance
The Hyve Chassis represents the pinnacle of competition rifle chassis design—born from extensive R&D, elite shooter feedback, and a relentless pursuit of performance.

Recoil Control
With its ultra-wide forend, low bore-axis, and optimized internal structure, the Hyve offers next-level recoil control for faster follow-up shots and improved shot-to-shot consistency.

Adjustability Without Compromise
Built to fit every shooter, the Hyve features a toolless adjustable cheek rest, a length-of-pull range from 11.8″ to over 14″, and a height- and cant-adjustable buttpad. The trigger guard is also fore/aft adjustable to eliminate magazine wiggle during high-pressure barricade shots.

True Modularity
Customize your rig with modular M-LOK forend panels, QD mounts, internal weight pockets (5 total), and accessory options like control bridges or barricade stops. The 3-part chassis design allows for future upgrades to stocks, forends, and inlets—your setup grows with you.

Built to Compete
Machined from 6061 aluminum and Type III hardcoat anodized, the Hyve chassis is ready for hard use. Premium torque hardware throughout ensures long-term durability and reliability.

Note: Shown with optional control bridges and extended barricade stop. Backordered items ship in 8–12 weeks.
