K-SPEC Enhanced AR15 Bolt- 5.56/ 300 Blackout, Dual Ejector, DLC Smoke Grey

The K-SPEC dual ejector system uses mil-spec ejectors and springs that require no proprietary parts.  Ejector holes are centered on the lugs to avoid any reduction in strength of the bolt.  The dual ejector system increases the ejection reliability and adds consistency to the ejection pattern. KAK Industry has been manufacturing dual ejector bolts for the AR10/LR308 platform for over a decade and has used that experience to create a durable and reliable dual ejector system for the AR15 platform.

The K-SPEC Bolt is backwards compatible with all standard mil-spec BCG components.  The K-SPEC bolt can be used in any AR15 style direct impingement system.

DLC (Diamond-Like Carbon) coating is a type of thin film coating that mimics the properties of diamond. It’s known for its exceptional hardness, wear resistance, and low friction characteristics. DLC coatings are applied using various techniques and are widely used in industrial, automotive, and consumer applications.

Properties of DLC Coatings

1. Hardness: DLC coatings are extremely hard, often approaching the hardness of natural diamond. This makes them highly resistant to abrasion and wear.
2. Low Friction: The low friction coefficient of DLC coatings reduces friction between surfaces, which can enhance the performance and longevity of moving parts.
3. Corrosion Resistance: DLC coatings provide good resistance to corrosion, protecting the underlying material from degradation due to environmental factors.
4. Chemical Resistance: They are resistant to many chemicals, which makes them suitable for harsh environments.
5. Optical Properties: DLC coatings can be transparent or have a black appearance, and they can be tailored to have various optical properties depending on the application.

How DLC Coating is Applied

DLC coatings are typically deposited using one of the following methods:

1. Chemical Vapor Deposition (CVD): This process involves creating a gas-phase precursor that decomposes on the substrate surface to form the DLC film.
2. Physical Vapor Deposition (PVD): Similar to other PVD techniques, this involves vaporizing a carbon source in a vacuum and allowing it to deposit onto the substrate.
3. Plasma-Enhanced CVD (PECVD): This technique uses plasma to enhance the chemical reaction that deposits the DLC coating.
