Good to hear. I have been curious about gunbloke. I haven’t found many reviews on them. I had an xbolt and used the mcarbo spring. It did make the trigger lighter, however it never felt light enough and the pull weight felt inconsistent.I guess I'm in the minority but I wasn't happy with the mcarbo spring. I bought one I liked a lot better off ebay from Gunbloke - located in Australia. They take a while to arrive but worth the wait.
