[ndlewin]

I have a G&P M4 and the upper receiver broke. I have bought a new one but I need to know, how do I get the barrel assembly off the upper receiver?

remove the front sight and gas tube , then use an AR spanner or if you get get 1 a rubber belt pipe remover and turn the barrel nut clockwise ( if you holding the body with the barrel away from you
it will be stiff but will move

looks like this is a G&G and the front sight cannot be removed.

Anyone have any ideas how I take out the gas tube?
