This video shows how to disable the blow back feature of your APS AK74 gel blaster to run higher rate of fire or 11.1v batteries.
The system is designed to run 7.4v batteries at a rat of fire of up to around 8 rounds per second, a higher rate of fire is likely to cause the blow back cycle system to fail which could cause the small metal that can fail to fall into the gearbox that could cause issues with the gears internally.
This is most commonly caused by running an 11.1v battery on a stock standard AK74.
