WildBoneZ Posted Saturday at 21:56 Share Posted Saturday at 21:56 Hi All, Brand new MP7 seems to have a bit of an issue where it doesn't want to fire, If I cock it back with no magazine it will dry fire, however inserting the magazine in and cocking back I get nothing. Happened to me before chrono today and lucky I had my back up as had no time to tinker, once I got home it cocked back and fired every single round with no stoppages. no signs of bbs or anything else stuck in the barrel, only thought is I may have overfilled the mag with bbs but unsure. Ive ordered an upgraded DCC industries sear as I've heard the stock TM ones can give issues. Any advice appreciated! Link to comment Share on other sites More sharing options...
Diablo675! Posted Saturday at 23:26 Share Posted Saturday at 23:26 What type of feeling do you get from the trigger? soft, squishy or does it just feel like a dead trigger? has the chassis been removed fully cleaned and lived lately? tm Mp7’s are known for intermittent working if they are over lubed. the seat sometimes fails and the steel sear is a good replacement if can find one.

WildBoneZ Posted Sunday at 11:14 Author Share Posted Sunday at 11:14 Soft and Squishy would be the best way to describe it actually. Noticed the bolt/dust cover does not fully return when the issue happens as well. Good advice I'll give it a good clean down and re lube. Link to comment Share on other sites More sharing options...
Diablo675! Posted Sunday at 16:43 Share Posted Sunday at 16:43 If it’s soft and squishy have a look on YouTube for a video that explains how to modify the hammer and check the sears. they are over moulded from factory so after time they give the feeling of the dead trigger yeah the chassis only needs very light greasing and the piston needs oiling every 20 mags or so for it to be decent.

Decp369 Posted 6 hours ago Share Posted 6 hours ago I’ve got a new mp7 & noticed similar issue with mine. I took out the nozzle & lubed up. When I reload & release the bolt it doesn’t go all the way forward therefore giving it a dead trigger. If you release the mag manually cock it then it works fine. One person did mention the gas freezing up some parts but don’t know if this is true. doesn’t happen all the time but obviously shouldn’t be happening at all Link to comment Share on other sites More sharing options...
