Hello,
I have a WASR AK47. I was out shooting it today, and I noticed that after it was warmed up when I closed the bolt (with or without bullets) steam would come out of the gas tube crimp as pictured. That part of the gun is also slightly discolored. I'm pretty new to AK's and was wondering if this is normal or not? Everything was functioning fine so I'm inclined to think this is not a big deal, but It almost seemed like a leak of some sort? I own it now so if this is a problem how hard is it to fix? ~Thanks https://www.dropbox.com/s/hqb9ebgl5bvpenq/IMG_0496.JPG?dl=0 |

| That's not a crimp, but instead where the gas tube (not really a gas tube, more of a piston guide) meets the gas block. Field strip the rifle and you'll see how it interfaces. Those holes in the gas block are vents, so if gas/smoke/steam/crud is coming out of it then it's doing it's job. |

| The AK is designed so the gas pulse knocks the piston to the rear with just the quick jolt it gets before the piston head clears the vents you referenced, dropping gas pressure. Originally the gas tube had the vents but they later put them on the gas block and stopped drilling the gas tubes. |
| Without the gas tube? Yeah, it would fire and eject but the piston probably would miss the center of the gas port on the way back, stop on the edge of the gas block and that would be it. I like the idea of dropping 'gas tube' and using 'gas piston guide tube'. |
