I think Placebo effect is starting to take place here.. The max the FAL can fire at is about 500 rpm there no way u can fire faster than that. If u do it will skip and make u fire slower. everyone's macro is made in a diff way.. but the end effect is the same they all fire at or close to the 500 rpm range. Same thing with the CHICOM all im trying to do is find a rapid fire that fires at the max rpm for this gun or a lil less to reduce recoil, which is 1250rpm its almost triple the speed of the fal. Apex made a Weird RF for the CHICOM but it dint work very well for me it skipped a lot so i couldn't use it.
