DLC Disclaimer:
All major components (Carrier, Gas Key, Cam Pin, Bolt, Extractor) will be DLC.  WCArmory has given Microbest permission to substitute phosphate for small parts such as the extractor pin, the ejector pin, and the firing retaining pin when Micribest can not source DLC coated parts.  WCArmory felt the black phospate was a better match for DLC than chrome.  Please assume the small parts listed above are phosphate parts are coated, WCArmory will not update the product specs for every batch.  All major components (Carrier, Gas Key, Cam Pin, Bolt, Extractor) will be DLC
