This replacement spring features spring steel construction with standard spring finish for 4390 ejection port door assemblies. Provides tension for proper ejection port door opening and closing. Drop-in replacement installation.
This spring provides the tension required for proper ejection port door opening and closing during the firing cycle. Adequate spring tension ensures the door opens fully during ejection and closes securely when at rest.
The spring steel material provides the resilience and fatigue resistance required for repeated compression and extension cycles. The standard spring finish offers basic corrosion protection while maintaining proper dimensional tolerances.
This spring functions as a direct replacement for worn or damaged springs in 4390 ejection port door assemblies. Installation requires no modifications and follows standard ejection port door assembly procedures.
This spring is designed specifically for 4390 ejection port door assemblies. Verify assembly compatibility before installation to ensure proper fit and function.
