    Very nice finish on all included parts. Fit my g&g combat machine no problem. The flat hop arm and nub that comes with hop unit is to short and at full hop there was no rubber protruding into the barrel (probably ok if using a R hop patch). Using standard arm with Prometheus flat hop nub you only get hop rubber protruding into the barrel on the second half of the adjustment, with a flat hop rubber. Side not check for burrs, I found burrs in both windows for the oring to stop bbs falling back out covering almost the whole window.
