My high capa is having troubles. I put a couple mags through it, same problem each time. I get between 5-10 shots then it will partially cock back and release all the gas. What is the problem? I look into the gun and feeding nozzle, blowback unit isn't going back all the way and I have trouble fixing it.
What's the problem and how do I fix it?

Are you shooting it outside in the cold? Also, it would help if we knew what brand the gun was and what type of gas you were using, as well as how long you've had the gun, when the problem first came up, if you did anything to modify the gun around then, if you dumped it in the mud at some point, stuff like that.

Sorry, I should've added that in the first place.
It's a we high capa. I got it from a friend, it's maybe three years old. It's been used with propane before I got it. Lost in a couch for a year and a half. My friend found it and gave it to me, I cleaned it and got a new mag. I kept the mag warm then I took it outside to shoot it.
I used green gas. The problem just occurred yesterday.

So, when you shoot a gas gun, you expel a quantity of gas. Some of the remaining liquid in the mag vaporizes in the mag to fill the space that the gas you just expelled vacated. When that happens, the temperature of the mag drops. That's not a problem on a hot day (as long as you're not rapid firing the gun) because the ambient temperature warms the mag up pretty quickly. On a cold day, however, the temperature is pulling the temperature of the mag down. If you start with a warm mag, put it in your gun and walk outside, the cold ambient temperature starts dropping the temperature of the mag immediately. Metal loses heat easily, so your propane is essentially uninsulated. The mag cools off very quickly. Now on top of that, when you fire a shot, the temperature of the gas drops (because of the chemistry and physics of how gas works) and instead of the warm outside air pushing the temperature of the gas back up, the cold air continues to pull it down. Your next shot is even colder, the following even colder still. That you even got 10 shots at all is something of a miracle.
You can't use gas guns in the cold. The gas pressure drops as the temperature does and you don't have enough power to cycle the gun. You can also freeze and crack the seals in your mags, which is bad.

That makes more sense. Thank you.
