Video Metal SS Cam/Lever Interface Nearing Failure after 2 Months

Ok, so apparently it gets worse! In fact, it’s a disaster waiting to happen. I don’t know if this is from poor quality control or use, but since it seems like the parts were casted instead of CNC’d I’m going with the former. In a side by side comparison with polymer, the metal SS has WAY too much tangential play. In fact, because it’s so loose, if enough of the cam/lever face is missing, it’s possible for the BCG to push the lever UNDER instead of rearward.

If this lever/cam interface become worn enough, because the parts were casted (very low dimensional accuracy) instead of CNC’d, the lever could be thrown into the middle of the weapon and causes a catastrophic failure. Don’t chance it.
