Two interesting videos from Airsoft Taiwan and RA-Tech. The first one is the WE AK74 part no. 107 which they find to have a problem that it's loose configuration makes its ROF low. They thus created their own version, which is heftier and CNC'd, and it fires at a higher ROF. If you want to give a name to it, you can send your suggestion, and if it they choose it, you get one of it.
