Performance and caliber considerations

.223 Remington / 5.56 NATO versatility

The dual listing of .223 Remington/5.56 NATO provides flexibility. For target work and light defensive duties, .223 Rem offers mild recoil and affordable ammo. When loaded to 5.56 NATO specifications, the platform can deliver higher-pressure performance for increased terminal effectiveness at practical engagement ranges. Always confirm barrel markings and ammo compatibility before loading higher-pressure rounds.

Ergonomics and accessory readiness

The 15″ M-LOK handguard lets users mount lights, foregrips, and sling points without adding excessive weight. The 6-position stock supports rapid length-of-pull adjustments for use with body armor or chest rigs. The Mil Spec OD Green finish reduces glare and provides a professional, subdued appearance suited to tactical applications.
