Product DescriptionMaxim Defense Industries SBA (Short Barrel Ammunition) is purpose-built for short-barrel rifles (SBRs) and AK pistols where traditional loads can suffer reduced velocity and inconsistent terminal performance. Developed in partnership with Fort Scott Munitions, this 7.62x39mm load uses Maxim's TUI (Tumble Upon Impact) projectile technology to create effective ballistic wound cavities that can outperform typical expanding and fragmenting projectile designs at short-barrel velocities. The TUI projectile is designed to tumble down to 500 fps for consistent performance in close-quarter and defensive applications.Product Highlights SBA (Short Barrel Ammunition) load optimized for reliable performance from short-barrel platforms 117 grain TUI (Tumble Upon Impact) projectile engineered to tumble down to 500 fps Solid copper projectile construction (lead-free design) for consistent terminal behavior Brass-cased, boxer-primed, reloadable ammunition for convenient training and field use 7.62x39mm rifle ammunition suitable for defensive use and practical hunting applicationsSpecs Brand: Maxim Defense Industries Manufacturer Part Number: MXM-49003 UPC: 680017490034 Cartridge/Caliber: 7.62x39mm Bullet Weight: 117 gr Bullet Type: TUI (Tumble Upon Impact), solid copper Case Material: Brass Primer Type: Boxer Reloadable: Yes Rounds per Box: 20 Rounds per Case: 200 Country of Origin: USADisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
