ACM M500 major leaking issues

[Four Leaf]

Hi everyone,

A while ago I bought a rather nice M500 ACM shotty and it did the business for me and held it's gas very nicely.

However, I recently left the gas chamber empty after forgetting to put a bit of gas in and when I went to fill it yesterday the green gas was literally going in and straight out again. Obviously a major leak somewhere but I've no idea where, other than the gas leaking noise got louder by the what would be the shell ejection port on the gun if it were real.

Any help at all would be greatly appreciated.

Thanks, FL

take out the gas block at tighten the nut at the end where the barrel slots into. and hilst ypu have the block out, unscew the rear of the block where the hammer hits and spray some silicon lube into it, to freshen up the seals

remove gas block assembly and fill with gas then submerge in warm water . this will reveal any leaks. fix and redo the test till you stop the leaks. works a treat every time
