Fort Scott Munitions 5.56x45mm NATO 62gr TUI SBS Rifle Ammo - 20 Rounds

Fort Scott Munitions 5.56x45mm NATO 62gr TUI SBS rifle ammo is engineered for shooters who demand performance beyond standard mil-spec rounds. The Tumble Upon Impact (TUI) design sets this ammunition apart—rather than relying on traditional expansion, the projectile is engineered to tumble and fragment upon impact, creating a distinct wound channel. This 62-grain load in 5.56x45mm NATO delivers the velocity and ballistics you expect from a rifle cartridge, with the added terminal performance that separates duty-focused ammunition from range-only options.

Fort Scott Munitions builds their rounds with solid brass cases and hand-tuned quality control, making them a choice for shooters who understand that ammunition is where precision truly happens. Whether you're training for defensive scenarios, testing duty ammunition for your platform, or simply want to experience what engineered terminal performance feels like downrange, this ammunition rewards careful marksmanship. Each box contains 20 rounds, letting you evaluate the round's performance or build a small reserve without overcommitting to an unfamiliar load.

The 62-grain weight sits in a practical sweet spot for 5.56x45mm—heavier than standard 55-grain loads but still manageable in most AR-15 and similar platforms. If you've been shooting generic mil-spec ammo and wondering what a purpose-built cartridge can do, Fort Scott Munitions' TUI line is worth a trip to the range.
