Breaking Down the Features of Superlative Arms AR15 Bolt Carrier, Direct Impingement
Specifications
The Superlative Arms AR15 Bolt Carrier, Direct Impingement is constructed from 8620 steel, a standard for durability in AR-15 components. Its weight is listed at 9.3 oz, which is within the typical range for a full-auto rated carrier. The key highlight is the chrome-lined bore, adhering to mil-spec standards for enhanced durability and corrosion resistance. Furthermore, it features a superior Diamond-like Coating (DLC), offering exceptional lubricity, reduced friction, and making cleaning significantly easier. The gas key is also DLC coated and secured with Optimized Carrier Key Screws (OCKS) developed by Ned Christiansen, ensuring superior staking and screw retention. This carrier is designed to be compatible with all AR-15 bolts, giving users the flexibility to select their preferred bolt.
These specifications translate directly into tangible benefits. The 8620 steel provides a strong, resilient foundation, while the chrome lining protects against wear and gas erosion, crucial for the longevity of any direct impingement system. The Diamond-like Coating is a standout feature; its inherent lubricity means less friction during the cycling process, leading to smoother operation and reduced wear on other components. This coating also makes it notably easier to remove carbon buildup, simplifying the maintenance process significantly. Finally, the OCKS gas key attachment is a testament to Superlative Arms’ attention to detail, addressing a common failure point in some other carriers by ensuring the gas key remains securely fastened.
Performance & Functionality
The primary job of a bolt carrier group is to reliably cycle ammunition, and this unit from Superlative Arms excels at it. In my testing, it consistently provided smooth and forceful cycling, from the first round to the last.
