This upper bridges the gap between a carbine and a lightweight support rifle: its quick-change barrel and dual-feed capability make it well suited for range training and precision or support-role shooting where rapid reconfiguration matters. The M-LOK handguard and top rail provide ample mounting options for optics and mission-specific accessories without adding unnecessary bulk.
