Key Features
Construction & Materials
The SCALPER integrates core components validated for durability and performance. It features a high-quality barrel and a robust bolt carrier group, recognized as critical elements for accuracy and longevity within a combat-grade weapon system. All internal components, including the buffer system, are meticulously selected for resilient operation, reflecting a focus on sustained hard use and component integrity.
Barrel & Muzzle System
