Any suggestions on getting a used gas tube out of an upper? I can't seem to budge it. I don't want to damage it. Yes I removed the pin before trying to disassemble. Any tips or suggestions would be appreciated.

Thanks. Has anyone seen a tool specifically for clamping to gas tubes. I believe I saw something like that a year or so ago. |
Yes Brownells and Bushmaster sell them. Scott |

I have removed and installed several gas tubes and the best method I have come across for removing them is to hold your upper upside down and clamp the gas tube in a vice (you can wrap the tube with tape if you dont want to mar the surface). Twist the upper back and forth a couple of times. This will break the carbon seal in the gas block/front sight tower. You can then wiggle the tube out with a pair of vice grips or pliers. Also, I assume you are going to replace the used tube with a new one so don't worry about putting a little elbow grease into pulling the old one. These tubes are actually made a fairly thick stainless steal. It takes alot to do any damage to them. Hope this helps. |
