Features
The K-Spec dual ejector system is a high-performance upgrade designed to enhance the reliability and consistency of ejection in your AR-15. By utilizing mil spec ejectors and springs, the system avoids the need for proprietary parts, ensuring easy maintenance and replacement. The centered ejector holes on the lugs maintain the bolt's strength, preventing any reduction in structural integrity. This dual ejector system improves ejection reliability, leading to more consistent ejection patterns, particularly under demanding conditions. With KAK Industry's extensive experience in creating dual ejector systems for the AR10/LR308 platform, they've brought that same durable and reliable technology to the AR-15, making it an excellent choice for those seeking a rugged, high-performance BCG upgrade.
