yes. it will need to be removed.
you will need a vice barrel blocks made from hardwood some rosin barrel wrench and miscellaneous tools for removing the gas block.
never use a upper reciever block for mounting dismounting barrels. torque from the barrel wrench can easily bend/warp/distort the upper.
if you were near se wisconsin could do the job in about 20 minutes
