Hey guys,

I apologize if this problem has been posted before, I took a quick look through the Doctor's Corner and did a search and nothing specific came up.

Anyway, when the gun is fired the bolt cycles very oddly. I have two mags for the gun, each mag has a different effect.

I've noticed in the other WA threads that sometimes mag type (i.e. brand) can play a factor, so I'll describe the appearance and feel of the mags as best I can to help others identify what brand they are.

Mag 1)
This mag is a heavier, darker coloured mag (I think the other threads had said this one is possibly stock WA?). When this mag is filled with gas and put into the gun to be fired, the trigger is pulled back, the hammer strikes forward but no gas comes out. I've even tried removing the upper receiver with the lower trigger assembly in tact and with a mag in, to see if the gas will release in that case, and no go.

Mag 2)
This mag is much lighter, both in weight and in colour. It's a light-ish grey, no Colt markings on the bottom I don't think.
When this mag is fired, the bolt will cycle back VERY quickly, but not all the way. The bolt cycles maybe a quarter of an inch backward (just enough to reset the trigger) and returns to battery after until the gas is out. Sometimes, it will only go for a few shots and then the rest of the gas will sputter out and the entire remaining quantity of gas will be expelled.

In any case, any and all help is appreciated. Will take any suggestions and try them, not too sure what the problem is with this gun. Apologies once again if this problem has been posted before (and moreso if it's been solved).

Thanks in advance.
