The MDT TAC21 (Tactical Application Chassis) is a drop-in chassis system that transforms the Tikka T3 into a more adaptable platform for tactical, precision, or hunting applications. It is constructed from high-quality materials, primarily 6061-T6 aluminium, with a Cerekoted finish for durability and corrosion resistance. The chassis is designed to improve accuracy, modularity, and user customization while maintaining compatibility with the Tikka T3’s factory action and barrel in .308 Winchester.

Key Features

1. Construction and Materials:
• Material: CNC-machined from 6061-T6 aluminium, ensuring strength and lightweight performance.
• Finish: Cerekoted
• Weight: Approximately 3.5–4 lbs
2. Modularity:
• Forend: The free-floating forend is M-Lok compatible, enabling the attachment of accessories like bipods, lights, or night vision devices. The forend is rigid, reducing barrel flex and improving accuracy.
•  
• Magazine System: The chassis accepts Accuracy International Chassis System (AICS)-style detachable magazines, which are widely used in precision shooting. For the Tikka T3 in .308, it typically uses 5- or 10-round AICS magazines.
•  
3. Barrel and Action Integration:
• Drop-In Design: The TAC21 is specifically designed for the Tikka T3 action, requiring no permanent modifications to the rifle. The action is secured using the factory Tikka T3 action screws, ensuring a precise fit.

• Free-Floating Barrel: The chassis ensures the .308 barrel is free-floated, eliminating contact with the stock to enhance accuracy by reducing external pressures on the barrel during firing.

• Bedding: The chassis features a V-block bedding system, which provides a stable and repeatable mounting surface for the Tikka T3 action, improving consistency and accuracy.

1.      Ergonomics and Adjustability:

o    Pistol Grip: Compatible with standard AR-15 pistol grips, allowing users to choose their preferred grip style for comfort and control.

o    Trigger Guard: The oversized trigger guard accommodates gloved hands, making it suitable for cold-weather or tactical use.

2.      Mounting Options:

o    Top Rail: The chassis includes a full-length 20 MOA Picatinny rail for mounting optics, providing ample space for scopes, red dots, or night vision systems.

o    Accessory Rails: M-Lok slots on the forend allow for easy attachment of bipods, slings, or other accessories, enhancing versatility.
