Gas Pisses Out of the Barrel.

ICS BM9... 

 

Had this for a while and bought it off a fellow AFUK member. All was well when I was plinking in my back yard however I’ve taken it out just today for a spot of target practice before Saturday’s game and on both mags it fires, misses a shot fires, misses a shot and then just sh*** itself by blowing all of the gas out of the barrel. 
 

Had a look online prior to this and I couldn’t really find this specific issue. 
 

Any help o you gas gurus out there? 
 

Thanks,

Drop in temperature ?, most common cause of venting/dumping, & it's def much cooler today than it has been (at least where I am on the south coast it is)

Absolutely fine. No issues, must’ve been the temp. Good call *old fosters advert*
