Fort Scott Munitions TUI 5.56mm 70gr Solid Copper Ammunition, 20-Round Box

Fort Scott Munitions Tumble Upon Impact (TUI) 5.56mm 70-grain solid copper spun ammunition (part no. 556-070-SCV2) is engineered specifically for home-defense and barrier-blind rifle work. Fort Scott Munitions machines this bullet from solid copper with a design built to tumble and fragment predictably on impact, reducing the over-penetration risk of a standard FMJ round through interior walls. For a home-defense AR-15 or barrier-blind engagement, this rifle ammunition is purpose-built for the role.

Frequently Asked Questions

What makes TUI different from standard 5.56mm FMJ ammunition? TUI is engineered to tumble and fragment predictably on impact, which is intended to reduce the risk of a round passing through interior walls or barriers compared to a standard full metal jacket bullet.

Why is the bullet solid copper instead of lead-core? Machining the bullet from solid copper avoids a lead core entirely, giving Fort Scott precise control over how the bullet behaves and fragments on impact.
