CHASSIS & UPGRADE KITS

The high-precision rifle chassis, AR15 kits, and accessories offered here are designed to enhance the ergonomics, modularity, and performance of modern firearms. Machined aluminum chassis deliver greater rigidity compared to traditional stocks, improving shooting stability and shot-to-shot repeatability even during extended strings. AR15-specific kits include components for replacement or upgrades, such as adjustable stocks, modular handguards, ergonomic grips, and additional mounting interfaces. Complementary accessories—adjustable buttplates, M-LOK or KeyMod systems, integrated Picatinny rails—allow deep customization to suit shooting style, shooter morphology, and application, whether for sport shooting, tactical use, or hunting.

Replacing or installing a chassis or AR15 kit begins by securing and fully disassembling the firearm according to the manufacturer’s guidelines. The new chassis is mounted to the action or receiver with strict torque control to ensure rigidity and consistency. Adjustable elements such as stock length, cheek rest height, and rail placement are then tuned to optimize shooting position and comfort. Accessories can be added at any time via the integrated interfaces, making it easy to evolve toward new configurations.

A quality chassis or AR15 kit should be precisely machined from robust materials such as aerospace-grade aluminum or reinforced composites, offering an excellent stiffness-to-weight ratio. It must integrate standardized attachment points (M-LOK, KeyMod, Picatinny) and provide fine adjustments to fit each user. Compatibility with a wide range of actions or AR15 setups, resistance to wear and environmental conditions, and a durable, high-quality finish are all essential. Accessories should complement the platform without compromising balance or reliability.
