| Need to remove a barrel extension pin, can do it destructively but are there any other suggestions . Or how do you do it? |
|
Why are you removing the extension? They generally are never removed or replaced, so there isn't a procedure in the TM.
You are aware that extensions are not swappable on barrels that have had the gas port drilled? Assuming you're doing a gas operated build of course. BSW |
| Do you know how to remove an extension pin??? If so how did you do it. or have you read anywhere on how it may be done. I can get it out by drilling in the mill.Just looking for someone that has done it.I don;t care to take the time to go into why or extension timing. or gas port drilling and indexing. thanks |

thanks for that suggestion, Had not thought about a little heat. I want to change the chamber slightly. so need to remove the extension. Bad idea pulling the barrel extension to just re-ream. Instead ream the barrel with the extension in place. The barrel extension is installed at around 150ftlbs of torque, and as stated, when you go to reinstall it, it's not going to align as it was before when correctly torqued, leaving the gas port and even the FSB ( if tapered pinned) off index with the barrel extension pin. |
