Use larger mags than your 15 round mags.
The whole "super powerful + tiny little gas reservoir" isn't going to work in your favor.
Try to avoid mixing brands of parts, I've noticed you've got some guarder and some SD parts... Generally you want to stick to all one brand if possible.
Get a new can of gas... (what gas are you using anyways? Get an AI propane adapter and use propane!!)
Are you sure you're filling it right? (mag upside-down, gas up-side down so the liquid gas goes into the mag)
