Maxim Defense SBA 7.62x39 117gr Solid Copper Ammo - 20 Rounds (MXM-49003)

The Maxim Defense SBA 7.62x39 117gr Solid Copper Ammo is purpose-built ammunition engineered to optimize performance in short-barrel rifles where velocity and terminal performance are often compromised. Developed through a partnership with Fort Scott Munitions, this 20-round box delivers rounds tuned specifically for the ballistic challenges of SBR platforms, ensuring consistent energy transfer and predictable wound ballistics downrange.

At the heart of this ammunition is Fort Scott Munitions' TUI (Tumble Upon Impact) technology, integrated into the solid copper projectile design. The TUI concept drives consistent terminal expansion behavior that exceeds the performance envelope of conventional expanding and fragmenting projectiles. This engineering approach prioritizes reliability in close to intermediate-range engagements where SBRs are typically deployed—whether in defensive scenarios, tactical training, or specialized hunting applications.

Each round is loaded to specifications that account for the shorter sight radius and reduced barrel time inherent to SBR platforms. The 117-grain solid copper bullet weight strikes a balance between velocity retention and energy delivery, making it a practical choice for operators running compact 7.62x39 rifles who refuse to compromise on terminal ballistics. This ammunition represents a meaningful step beyond generic 7.62x39 loads that treat all barrel lengths the same.

Frequently Asked Questions

Is this ammo designed specifically for short-barrel rifles?

Yes. Maxim Defense SBA ammunition is optimized for short-barrel platform ballistics through load adjustments and projectile engineering developed in partnership with Fort Scott Munitions. Standard 7.62x39 loads don't account for the reduced velocity and performance characteristics of shorter barrels, which this ammunition does.

What is TUI technology and how does it work?

TUI (Tumble Upon Impact) is Fort Scott Munitions' projectile design philosophy where the solid copper bullet tumbles through the target to 500 fps, delivering terminal ballistics that exceed conventional expanding and fragmenting round performance standards.

What's included in a box of Maxim Defense SBA ammo?

Each box contains 20 rounds of 7.62x39 ammunition loaded with 117-grain solid copper projectiles.
