Detailed Description

Sons of Liberty Gun Works looks at the bolt carrier group as the heart of the gun. If the gas port is the lungs, then the bolt carrier group is the heart. It’s what drives the entire gun.  As such SOLGW crafted their Scalper bolt carrier group with precision and engineered for excellence, this BCG sets new standards for reliability and functionality. Meticulously machined from premium materials, it ensures seamless operation, reduced friction, and enhanced durability.  Building on their industry-leading Carpenter BCG, the Scalper adds FCD’s OCKS Key Screws as an extra layer of enhanced reliability.
