I feel like I should know this from assembling a couple ARs before, but I better ask before I go ahead with my grand scheme. (I don't have an AR in front of me currently so its hard to look at and make sure)
Can the gas tube be removed and replaced without removing the whole front sight block? Using a standard A2 sight. Simply remove the gas tube roll pin and push it out of the front sight post, then pull it forward out of the receiver.....or will the angle and tolerances prevent that?
(I'm trying to replace the upper receiver not the gas tube. The gas tube prevents removing the delta ring assembly.)
Thanks. And I
