TM MP7 gas mag issue

[SnakeDoctor87]

Hey all,

Wondered if you could help work out and issue I have with one of my 5 tm mags for my mp7.

So I was at a game last night and blew through 3 of my 4 mags, they all worked fantastic considering they're second hand. But I got to my fourth mag and noticed that it wasnt firing with full power. The mag has no leaks, I use .20 tracers bbs with abbeys green gas equivalent. I fully gassed the mag up prior to the games and in two games had the same issue. It would fire the first round full power, then kick out a few rounds like it was nearing the end of its gas. You know that weak sound you get. Then it would fire a few rounds as normal then go back to being weak.

I have no idea whats causing this.

Any ideas peeps?

Thnx in advanced, 

Snake ?

Empty the mag, put some lube into the hammer valve at the back of the mag, and push it in and out all the way a few times to both spread the lube out, and to test full travel.
