FEATURES:

Built around the proven 5.56 NATO platform, the Shark Coast Tactical M-81 is engineered to deliver dependable performance, adaptable ergonomics, and a distinctive visual identity that stands apart from standard configurations. Chambered in 5.56 NATO, this rifle is well suited for a wide range of applications including range training, sporting use, and general-purpose shooting where reliability and controllability are essential. The caliber provides a balanced combination of manageable recoil, flat trajectory, and widespread ammunition availability, making the rifle practical for both experienced shooters and those looking to expand their collection with a versatile modern firearm.

A 16-inch barrel anchors the rifle’s performance profile, offering an effective balance between velocity, accuracy, and maneuverability. The barrel is finished with a Black Nitride treatment, enhancing surface hardness and corrosion resistance while promoting long-term durability under repeated use. The threaded muzzle allows for compatibility with a variety of muzzle devices where permitted, giving the user flexibility to tailor recoil management and shooting characteristics to personal preference. This barrel configuration supports consistent shot placement and reliable cycling across a broad range of ammunition types.

The aluminum receiver is finished in an M-81 Woodland Camo Cerakote, giving the rifle a classic military-inspired aesthetic while also providing a durable protective coating. Cerakote enhances resistance to wear, abrasion, and environmental exposure, helping the finish maintain its appearance through extended handling and use. The integrated Picatinny rail on the receiver allows for straightforward mounting of optics and accessories, supporting modern sighting solutions without compromising rigidity or alignment. This setup enables shooters to configure the rifle with red dots, scopes, or magnifiers to suit their intended use.

Surrounding the barrel is a free-floating M-LOK handguard designed to balance strength with reduced weight. The M-LOK system allows for direct attachment of accessories such as lights, grips, and sling mounts while maintaining a streamlined profile. By keeping the barrel free from external pressure, the handguard contributes to consistent accuracy and improved heat management during extended shooting sessions. The slim profile also enhances control and comfort, especially during dynamic handling.

At the rear, the Magpul SL-K black polymer stock provides a compact and sturdy interface between the shooter and the rifle. Known for its durability and practical design, the SL-K stock offers a stable cheek weld and reliable shoulder support without unnecessary bulk. Paired with a black polymer grip, the rifle delivers a comfortable and secure hold that promotes proper trigger control and reduced fatigue over time. The grip’s ergonomic shape supports natural hand positioning, which is particularly beneficial during longer range sessions.

Configured for right-hand operation, the Shark Coast Tactical M-81 maintains familiar controls and intuitive handling for the majority of shooters. A standard 30+1 capacity ensures ample round count for extended shooting without frequent reloads, aligning with expectations for a modern sporting rifle in this class. The magazine capacity supports training, recreational shooting, and practical applications where consistency and readiness are valued.

Every component of this firearm reflects a focus on function, durability, and modern styling. The combination of a nitride-treated barrel, Cerakote-finished aluminum receiver, and modular furniture results in a rifle that performs reliably while offering visual appeal rooted in the iconic M-81 woodland pattern. As a complete package, the Shark Coast Tactical Rifle delivers versatility, customization potential, and proven 5.56 NATO performance in a cohesive and well-balanced platform designed to meet the demands of today’s shooters.
