Fierce Firearms Lachstu Long Action Chassis Kit - Tungsten Finish

The Fierce Firearms Lachstu Long Action Chassis Kit in tungsten finish is a precision rifle chassis designed to transform your long action setup into a modern, ergonomic platform. This chassis kit gives shooters the rigid mechanical foundation and intuitive controls that AR-pattern rifles have made standard, now adapted for long action magnum calibers and hunting applications where conventional stocks fall short. Whether you're building a dedicated long-range rig or upgrading an existing platform, the Lachstu brings contemporary handling and modularity to a traditionally conservative form factor.

Built around long action dimensions, this chassis accommodates the larger magnum and standard long action bolt faces common in hunting and precision rifle disciplines. The tungsten finish offers a durable, professional appearance while resisting corrosion—practical for hunters working in variable conditions. The modular design lets you configure controls and ergonomics to suit your shooting style, reducing setup friction when switching between rifles or swapping configurations for different seasons or competitions.

The Lachstu represents a growing trend in rifle modernization: taking proven chassis-system principles and making them work across diverse action types, not just short actions. If you run a long action magnum and have felt constrained by traditional furniture, or if you're assembling a new rifle and want the handling benefits of a chassis platform, the Lachstu bridges that gap without forcing you to change actions or calibers.
