broklebean Posted February 3, 2013 Share Posted February 3, 2013 Hi guys I'm going to the mall on 24th and there limit is 328fps. My rifle a ICS M4 CQB is very close my last chrono was 329fps with .2g bb and the battery was fully charged 8.4v. Now I'm using a 9.6v battery I know that this wont affect FPS but I'm just giving as much info as pos. any ideas how to drop the FPS slightly?

the_robbo Posted February 3, 2013 Share Posted February 3, 2013 You won't need to, its 328 with a max variance up to 340 Link to comment Share on other sites More sharing options...

ScoobySnacks Posted February 24, 2013 Share Posted February 24, 2013 Your velocity will vary up and down by a few FPS. Trying to get an exact velocity is a waste of time, and trying to drop the velocity by a few fps is also a waste of time. You say it was 329, but what was the max and min? My MP5 varies shot to shot between 300 and 320. The variance depends on the quality of the gun, air seal, spring etc. Link to comment Share on other sites More sharing options...
