Haus-416 Billet Lower

While a limited number of manufacturers offer HK-spec 416-pattern lowers, the process typically involves paying nearly twice the cost, enduring extended lead times, and then shipping the receiver to a third party for correct HK-style markings and finishing.

At $499.99, our solution eliminates those compromises. Every lower is fully machined, engraved, and coated in-house, ensuring complete control over quality, consistency, and turnaround time. By handling the entire process internally, we deliver a finished 416-spec lower that ships faster, costs less, and meets a higher standard of fit, finish, and accuracy than comparable offerings on the market.

No outsourcing. No delays. No inflated pricing—just a complete, ready-to-build lower produced start-to-finish under one roof.

The A1/A5 hybrid architecture of our lowers is the result of a focused research and development process, informed by industry consultation and platform analysis. By selectively integrating the strongest design characteristics of both generations and eliminating their limitations, we have engineered a refined 416-spec receiver that sets a new benchmark in precision, functionality, and platform fidelity.
