Purchased a new gas block, inserted the gas tube, pinned the tube on, looked into the gas port, and noticed that about 1/3rd of the gas tube is protruding into the gas port, creating an obstruction.
Any quick solutions? |

I wish that were the case, but it's definitely not. Quoted:

You have the gas block turned around the wrong way. Remove the gas tube and reverse the gas block. I wish that were the case, but it's definitely not. the wrong way???? That's not even possible, is it? The block would have to have two roll pin holes. |

If you are in a hurry (don't want to get replacement) you would have to "open" up the hole in that gas tube so it does not cause a restriction.
If you do not have the tools you might want to just send it back for replacement. Do not try to do it when it is in the gas block. |

(yours has me baffled, as I'm sure it does you) |

Obviously either the tube or the block is out of spec.
For simplicity down the road I would determine which is out and replace it. Depending on what is off it may be possible to re-drill the offending part. Although you described your problem you have given us none of the pertinent information it would take to help you determine which part is bad. |

It's a Colt gas tube, so I highly doubt this is the offender. The gas block is out of spec. |

The port size of the barrel is the one that matters. Opening the gas block a little won't hurt anything. What brand gas block is it? Any respectable manufacturer will stand behind their product and send a replacement if you don't mind waiting. It's a Troy gas block, but I'm not going to modify the gas block. I'm going to elongate the port in the gas tube. |

If you can see the gas tube material inside the gas block the gas blasting up through the barrel's gas port will bent it up closing off the tube (or at least partially).
Get it replaced or CAREFULLY open it up to (hand fit it) get it out of the way. That port will have to be clear. Think of it this way: anything in the way will end up in your BCG. Also check to see that the gas tube properly fits into the port in the gas block. The fit should be fairly tight... you should feel the sides of the gas block when you slide the tube in. IF it is lose it will be more problems. |

Is it really 1/3 covered up? I am willing to bet it isn't quite that much as I just checked two different gas blocks with a gas tube and neither lines up just right. Maybe a 1/5 overlap. I have used several of both types and never had a problem.
Gas follows this law. Something about the path of least resistance and I am fairly certain the gas system doesn't go anywhere near as high as the barrel pressure because of how fast the bullet leaves the barrel. Not only do I think your set up will work fine, I seriously doubt the gas bends the tube and causes an obstruction. |
