TM M870 Breacher gas leak

[Madhouse]

Hi All,

Had a search and it didn't yield any results, so here I am.

I've a TM Breacher and yesterday when I inserted the gas tank it started hissing with a leak, the mag itself is fine. I've not taken it apart yet, but I'm figuring that either an o-ring has dried out or something's not tight enough, the issue's pretty close to the rear and from the parts diagram there's a couple of points where this could be the case.

Anyone had the issue before? or taken an M870 apart? do I need any special tools?

Am yet to use it in a game as I was waiting on some more gas tanks, ironically now it's developed a leak the extra tanks shipped today ?

Thanks.

Pulled it apart, the pistol grip screws were a real pain and seemingly made of cheese - so they're getting replaced - TM crushed/broke a couple of O rings when they put mine together, so am now awaiting replacements before I put it together again with some additional PTFE tape on the inlet valve for good measure.

Fingers crossed that'll fix the issue.
