MAXIM 7.62X39 - 117 GR - COPPER - 20 RDS/BOX
The Maxim Defense 7.62x39 117 Grain Copper TUI ammunition is purpose-engineered for short-barreled rifles, delivering devastating terminal performance even at the reduced velocities common in compact platforms.
- Optimized for SBRs — engineered to perform at shorter barrel velocities
- 117-grain solid copper projectile for deep, consistent penetration
- TUI (Tumble Upon Impact) technology activates reliably down to 500 fps
- Wound cavities that exceed both expanding and fragmenting projectile standards
- Developed in partnership with Fort Scott Munitions for proven ballistic data
- 20 rounds per box — ideal for defensive stockpiling and range evaluation
Who This Is For
This ammunition is built for shooters running 7.62x39 SBRs, pistol-configuration AKs, or other compact rifles where barrel length sacrifices muzzle velocity. Whether you're building a home-defense setup, a truck gun, or a duty rifle, Maxim Defense TUI ammunition ensures your short-barreled platform hits with real authority — no hollow point expansion required.

Frequently Asked Questions
How does TUI (Tumble Upon Impact) technology work, and why is it better for SBRs?
TUI projectiles are machined from solid copper with a geometry designed to destabilize upon entering soft tissue, causing the bullet to tumble laterally and create a dramatically larger wound cavity than a standard FMJ. Because TUI activation relies on tumbling — not expansion — it works reliably even at the lower muzzle velocities produced by short barrels, functioning all the way down to 500 fps. This makes it a superior choice over hollow points in SBR applications, where there may not be enough velocity to guarantee reliable expansion.
Will this ammunition cycle reliably in standard AK-pattern rifles and AR-pattern 7.62x39 platforms?
Yes. Maxim Defense 7.62x39 TUI ammunition is loaded to function reliably in standard AK-pattern rifles, pistol-configuration AKs, and AR-platform rifles chambered in 7.62x39. The loads are specifically tuned to cycle actions even in shorter-barreled configurations where gas pressure can vary. As with any new ammunition, it is always recommended to function-test a box through your specific firearm before relying on it for defensive use.
Is solid copper ammunition legal to use in California?
Yes — solid copper (lead-free) ammunition is not only legal in California, it is required for hunting in many situations under the state's Nonlead Ammunition regulations. For range use and defensive purposes, solid copper ammunition faces no additional restrictions beyond standard California firearms laws. This Maxim Defense TUI load is a fully lead-free projectile, making it compliant with California's expanding nonlead requirements.
