    Essential Accessories

    Must-Have Accessories

    • Chamber flag: For safe storage and range use.
    • Trigger lock or cable lock: For basic security when not in use.

    Optics and Sighting Systems

    Compatible Optics

    • Red Dot Sights: Compact, fast-acquisition optics are ideal. Recommended: Trijicon MRO, Aimpoint Micro T-2, or Holosun HS503CU.
    • Low Power Variable Optics (LPVO): For extended range, consider the Vortex Viper PST Gen II 1-6x24.

    • Red dots offer rapid target acquisition in close quarters, ideal for the 7" barrel.
    • LPVOs provide versatility for both close and mid-range shooting.

    Rails, Grips, and Ergonomics

    • Vertical/Angled Grips: M-LOK compatible, such as Magpul M-LOK AFG or BCM Gunfighter Vertical Grip.
    • Hand Stop: For control and to prevent over-extension past the muzzle (Ergo M-LOK Hand Stop).

    Lighting Systems and Lasers

    • Weapon Light: Compact, high-lumen lights like Streamlight ProTac Rail Mount 2 or SureFire M600DF (M-LOK mount required).
    • Laser: If desired, Steiner DBAL-A3 (for professional/LE use) or Crimson Trace Rail Master for civilian use.

    Performance Upgrades

    Triggers, Barrels, and Internals

    • Trigger: Drop-in AR triggers such as Geissele SSA-E or CMC Flat Trigger for improved feel and reset.
    • Charging Handle: Ambidextrous options like Radian Raptor.
    • Muzzle Device: QD suppressor mounts (e.g., Q Cherry Bomb) for suppressor compatibility.

    Professional Installation

    • Bag Carry: Discreet cases like Vertx Commuter Sling or Hazard 4 Plan-B for transport.
    • Vehicle Mounts: Grey Man Tactical RMP panels for secure vehicle storage.

    Concealed Carry Considerations

    • Due to size, true concealed carry is impractical; focus on discreet transport solutions.
