Or at least I think 620 is the one recommended for bedding an AR barrel in to the upper receiver. Just how difficult is it to remove later? Are we talking fashioning a wooden dowel and using a dead blow hammer to get it loose later? Or just some elbow grease?
I am trying to determine how permanent it is as it makes me nervous to install a barrel in a receiver were replacing the barrel means effectively replacing the receiver also (or having to go to great lengths to get it loose).
Been working to accurize a build and I think it is an issue with the barrel, not the fitment. But I figure before going and tossing the barrel and getting a new one, I should do some work to make sure it isn't something else. Lapped the receiver and I need to get gauges (it SEEMS to be headspacing correctly looking at the brass). Group sizes are still rather large and I don't recall the barrel being loose in the upper, but figure it can only help.
Thanks.
