Help with MEU magazines

[john beattie]

Hello everyone
I bought a new TM MEU with a spare mag around eight month ago but have only started using it on a regular basis and have found that one of the mags will fire around 25+ shots on one fill but im only getting around 15 at best with the other, something i have noticed is when i use the one with the low shot count the first 3 to 4 rounds are realy powerful and there is quite a lot of gas blows back in my face, the mags are identical and are TM, is there a fix for this or its it that some mags are better than others.
im confident in stripping the mag down for inspection but though it would be best to ask thoses that know about this sort of thing first.
any help would be great
many thanks

Should be in the gas tech section mate, is the second definitely TM and not a WE? Could be due to cool down, are you firing the shots off quickly? Are you definitely filling the mags fully?

Hi
sorry for posting in the wrong place, can a mod move the post please
the second mag is definitely a TM im shooting in bursts of two and three with a max eight rounds per mag, but have tested with some slow shooting but still get the same result, its as if the first 3 to 4 rounds are letting out more gas than the other mag and it's just running out, im going to try and put it over the chrony and see if there is any big difference,im definitely filling well around 15 seconds with a new tin of gas.
thanks for your reply

have you made sure that the mag isnt leaking?

Re: Help with MEU magazines

Is there any signs of leaking from the dodgy mag? Were they stored with gas in them when you weren't using them?

Try holding the bad on under water to see if there is any bubbles...if so you many have a gas leak. Have you stipped the mag down, try removing the valve on both mags and see if there is any differnence if you swap them over. I would get a bottle of silicone oil and give all the o-rings a good soak and then reassemble it. LaZoucheCustom workshop has a good video on youtube about meu magazine maintanence, might be worth a look.

Thanks danhc and flangtal1ty
i always leave them empty when stored
i filled the bad mag and left it for around ten min but no difference still around 15 rounds, but im thinking it may stop leaking at a certain pressure so will try it under water like you say
i'll also do as you suggest and strip them both down and will take a look at the youtube video
many thanks
