TS-41 Achilles Posted April 21, 2016 Share Posted April 21, 2016 Recently I've just started playing airsoft and bought myself a Umarex MP5 A3 Sportline (two tone). After a couple of skirmishes I started to notice my gun was having issues all of which start with the trigger catching on something as I pull it fully back. 1: When the weapon is taken off safety and the weapon doesn't fire and there is no noise coming from the motor. 2: The weapon will fire for a short time then we are backbto problem number 1. 3: On semi-auto the gun can sometimes fire as though it is on full auto. These problems and not a constant but do happen often. Any ideas or advice on how to repair the problem would be great. I don't know much about airsoft gearboxes.

However, I had a umerex G36 Sportline that did the same thing, rather than return I decided to investigate and sort it myself. I found the back of the trigger was hitting at the back of the slot it sits in, I just filed the back of the slow and made in 1mm longer, this small amount of filing sorted it out and its still working well today. I think there is a little wiggle room on the switch that the trigger activates but the filing sorted my issue. Link to comment Share on other sites More sharing options...
