The configuration includes a 15.25-inch M-LOK rail, forged M4 flat-top upper receiver with forward assist, bolt carrier group, charging handle, A2 flash hider and complete lower assembly. It is chambered in 5.56x45mm NATO and uses a collapsible synthetic stock with a Mil-Spec trigger and selector safety.
