I was one of the original testers of their cylinder sets about 2 years ago, and they sent me a bore-up set (cylinder, cylinder head, piston head, nozzle, 2x springs). Ran beautifully in my M4 and my m249, and as far as I know it's still running 2 years later in the gun I sold them with. I have no clue if their QC has dropped since Echo 1 became their main US supplier though.
