I have a WE Tech Hi Capa 4.3

I usually fill in about 12 BB's and insert about 5 seconds of propane into the mags.

Most of the time I fire the first shot, loads of gas releases and then after 2-3 shots, the gas chamber is emptied.

It is inconsistent as sometimes I am able to clear the whole mags of 12 BB's.

Any ideas?

Thanks
