What It Is
SINTERFIRE 5.56X45MM NATO Ammunition is a centerfire rifle cartridge widely used in AR-15 style rifles and other platforms chambered for the 5.56 NATO specification. Each round is engineered for maximum accuracy, controlled recoil, and dependable ignition, making it ideal for a variety of applications, including range shooting, law enforcement, and military exercises.
Chemical Composition and Construction
Each SINTERFIRE 5.56X45MM NATO cartridge consists of a copper-jacketed lead projectile, a high-quality brass casing, and a smokeless powder propellant. The primers are carefully designed to provide consistent ignition in diverse environmental conditions. This combination ensures the ammunition performs reliably across different ranges, temperatures, and conditions, giving shooters consistent velocity and trajectory.
How It Works
Upon firing, the primer ignites the smokeless powder, generating high-pressure gas that propels the bullet through the barrel with controlled velocity. The design of SINTERFIRE 5.56X45MM NATO Ammunition ensures minimal barrel fouling, clean cycling, and reliable feeding in semi-automatic and automatic rifles. Shooters benefit from predictable ballistics, improved accuracy, and enhanced shot-to-shot consistency.
