So I'm currently in the process of upgrading my G&G GR16 or M4. And one of the upgrades I'm doing is adding a full metal body. But when i was in the process of removing the front barrel i came into a snag. This Metal pole going all the way across the top front part of my AEG and blocking the teeth to which i need to turn in order to remove the front barrel from the upper receiver. Anybody that has any idea into how exactly i should go about removing this damn obstruction so i can take off the front barrel would be great!
Just to get a better idea...
