K-SPEC Enhanced AR15 BCG, 5.56/ 300 Blackout- Dual Ejector, Side Vent, Sand Cuts, DLC Smoked Grey, Chrome Lined

Sand Cut Rails

For enhanced functionality in adverse and rugged conditions such as sand, mud, dirt, and grime. These rail cuts are designed for debris disbursement, resulting in ultra-high functionality in the toughest conditions, including suppressor fouling and foreign contaminates. Strategically located angle cuts in the rails result in fouling and debris being moved into noncritical areas that are not in contact with the receiver and do not affect the function of the firearm. aka sandcutter

Machined in house and assembled using only the finest steels and components. 

KAK Industry takes pride in producing some of the finest Mil-Spec/ Enhanced AR15 bolt carrier groups available, made 100% in house at our MO facility using Doosan machining centers, Tsugami Swiss turning, and the latest in FANUC robotics combined into an automated cell giving us lights out production capability.  In house automated CMM Inspection processes ensure consistent quality. 

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.
