Why Choose a Dual Ejector AR15 Bolt?

A standard AR15 bolt uses a single ejector, which can occasionally cause inconsistent ejection patterns. The dual ejector system in the K-SPEC bolt improves extraction and ejection reliability, making it especially valuable for suppressed builds, high round count shooting, and defensive applications. By spreading the work across two ejectors, the system reduces stress on individual components and ensures smooth function.

Full Chrome Finish for Maximum Durability

The full chrome finish adds an extra layer of protection against carbon fouling, corrosion, and wear. Chrome-lined components are known for their longevity, especially under harsh conditions. This makes the K-SPEC bolt an excellent choice for shooters who demand military-grade durability in their AR-15 platform.

Compatibility Across Platforms

The K-SPEC Enhanced Bolt is fully compatible with both Mil-Spec and enhanced AR-15 carriers, allowing you to drop it into your favorite bolt carrier group without modification. It works seamlessly in rifles chambered for 5.56 NATO and 300 Blackout, making it a versatile solution for multi-caliber shooters.
