Fightlite Industries 15076 Main Action Spring 223/5.56 NATO Rifle

The Fightlite Industries 15076 Main Action Spring delivers consistent cycling performance for 223 Remington and 5.56 NATO rifle platforms. This precision-engineered component ensures reliable bolt carrier group operation across varying ammunition weights and environmental conditions. Spring tension specifications optimize extraction and ejection timing for enhanced reliability.

What Makes This Different

Unlike standard action springs that may lose tension over extended use, the 15076 maintains consistent spring rates through thousands of firing cycles. The spring utilizes high-carbon steel construction with controlled heat treatment for dimensional stability. Testing shows maintained performance across temperature ranges from -40°F to 160°F, ensuring function in extreme conditions.

Key Features

• High-carbon steel construction for extended service life
• Precision wound coils maintain consistent tension rates
• Compatible with 223 Remington and 5.56 NATO chamberings
• Heat-treated finish resists corrosion and wear
