What Makes This Different

Nemo Arms manufactures this ammunition to meet M193 specifications, ensuring compatibility with both 5.56mm NATO and .223 Remington chambers. The boat tail design reduces drag for improved ballistic coefficient compared to flat-base projectiles. Quality control standards maintain consistent powder charges and overall cartridge length for repeatable performance shot after shot.
