So a friend gave me a century FAL but it will not eject shells. I am able to load a magazine and manually cycle all the rounds without an issue. When i do fire a round it will not eject. In fact after it is fired it is very hard for me to manually eject the shell. I have to slam on palm really damn hard to free it. Below is what i have done/checked. 1- Changed gas setting from 7 down to 1 2- Changed piston rod to a Tapco and changed springs 3- Changed the gas tube because it would slip out from gas block 4- Tried a different bolt no change 5- Tested with German Surplus and LC ammo |

Metric gas piston should work on a inch gun dispite being slightly shorter.
Last time I've seen this problem the gas plug was installed upside down. Check the plug to see where the burn marks are, if any. If it's inch pattern trouble shoot with the gas regulator set on 0, this closes the exhaust vent and the piston gets full gas. Once it runs then open it up fully and adjust so it runs smoothly. Lastly there is a chance the gas port isn't drill, you can look down the barrel with a light to see. |

Gas plug on A, because if it's on G you have a glorified single shot.
If that doesn't do it, Remove the plug take out piston and spring, remove spring from piston. Remove top cover, and lock the bolt in the REAR position. With the bolt in the rear position, take the now spring-less piston and drop it back in the gun. The rear tail of the piston should travel into the action for a couple of inches with ease... If this doesn't happen you either have a mis-timed barrel, or your piston rod hole is out of spec. |

They will fire but you won't be able to adjust the gas ! At least that's what I found out when I put one in my l1a1century fal. He most likely got the gas plug misaligned . |

remove/unscrew your front sight and check your gas port. I wanted to enlarge mine because I had the same problems. I could barley insert a sewing needle from the top, down into the bore.
There seemed to be some obstruction so I used a drill press, without turning it on to tap out the obstruction. Perhaps someone broke a bit off in there beforehand. When the gas port was clear, I opened it up with a 7/64 bit and good to go. |

check your retaing pin for the gas tube, it is located right behind the front sight .
take off your hand guards to check. most FAL's from century are made from kits and this the main cause for a short stroke gas problem. if your pin is missing just use a coat hanger and cut to length desired (it may fit losse but the hand guards will keep it in place) the pin keeps the gas tube snug so there is no gas leakage. I had the same problems on my 2 Century FAL's (1 metric ,1 inch),  good job everyone on the other info

I was at the range testing my Century FAL for the same reason and I didnt know a dam thing about
Fal rifles, lucky for me there was a guy there who was doing some shooting and he had built some FALs from kits. he is the one who showed me the coat hanger trick. (use the larger size coat hanger) would I use it for a range rifle all the time? NO would I use it to test fire a rifle and get some pin's on order YES. there are some good information on some other sites as to build an extractor disassembly tool for a FAL from a coat hanger. order some pins and wait to test your rifle or order some pins and test fire your rifle right away, pay $25 for a FAL extractor disassembly tool or make it yourself. so yea really. |

And you are sure about those hand guards holding the gas tube pin in place? Really sure? |

I had a similar issue with a Century L1a1.
The recoil spring tube was loaded with grease; greatly slowing down the bolt carrier to the extent that it would not extract. Also, the gas port had to be enlarged with a drill because Century chopped the last inch or so of the barrel off. Alsox2, a quick check with some headspace gauges showed that it was not properly headspaced by Century 
I think they hire drunken teenagers to do their rifle builds. |

| My century FAL was single shot for a while too and I new little about them. I took it to DOW arms room to have it looked over. After checking the headspace, barrel allignment, and gas assembly, he replaced the gas tube, and enlarged the gas port. He told me that the piston rods are made of a stronger metal than the tube and over time it can wear out the inner of the gas tube. My gas block was also worn out too and enlarging the gas port was an easy solution but only a temporay fix to get it running. I had to compair my gas plug and how it fits to my father's FAL. Both of our plugs were so loose in my gas block that they can be removed without pushing the detent pin. Just the opposite in his FAL. It runs on 308 right now but, will not cycle surplus 762. I'll be ordering a new gas block soon and change it out myself but, I'm glad to have someone that new the rifle give it a check up. |
