This video from The VSO Gun Channel compares the cleaning ease and performance of a Walker Defense Research DLC-coated bolt carrier group (BCG) against a standard nitrided BCG. The testing involved extensive live-fire under adverse conditions followed by a detailed cleaning comparison using Q-tips and a soap solution. The results suggest that the DLC coating, combined with Walker Defense's surface preparation, offers a tangible benefit in terms of easier cleaning and potentially smoother operation.
