The Maxim MXM-49002 5.56 NATO 70gr TUI SBA ammunition is purpose-built for shooters who rely on short-barrel rifles yet still demand consistent terminal performance. Each round uses a 70-grain Tumble Upon Impact (TUI) solid copper spun projectile, engineered to begin tumbling at lower velocities so it remains effective even when fired from compact platforms. Clean-burning components and quality brass cases support smooth feeding and reliable ignition shot after shot.

This 5.56 NATO load is well suited for training, range work, and close-range defensive use where dependable performance from short barrels is essential. The lead-free solid copper construction makes it a practical option for areas with restrictions on traditional ammunition while still offering stable flight and controlled terminal behavior. Maxim Defense is known for designing products around real-world use of compact carbines and pistols, and this ammunition reflects that same focus on thoughtful engineering and consistent performance.
