LANTAC 13.5" Stainless Rifle

The LANTAC 13.5" Stainless Rifle builder set is a complete upper receiver assembly designed for operators who demand precision, durability, and modularity in a mid-length rifle platform. Built by LanTac USA LLC, this set is ideal for competitive shooters, law enforcement, and military personnel seeking a reliable foundation for custom AR-platform builds.

Featuring a 13.5-inch barrel length, this assembly strikes an optimal balance between velocity, maneuverability, and sight radius, making it suitable for both close-quarters and intermediate-distance engagements. Constructed from stainless steel, it resists corrosion and extends service life in harsh environments, which is critical for operators in coastal or humid conditions.

This builder set is perfect for gunsmiths, experienced shooters, and armorer-level technicians who assemble and customize AR-platform rifles. At a verified weight of 0.81 lbs, the assembly maintains a lightweight profile without sacrificing material quality, allowing shooters to keep overall system weight manageable while preserving repeatability and accuracy.
