It'd be easier to make a new upper by hand than separate those parts. :p
We didn't need any loctite to get the "accuracy" fit on that build. :eek:

*Update* I was worried for nothing. The fit ended up being so tight I had to use an impact gun on the barrel muzzle to too drive it in.:happy:
Just kiddin! She was nice and snug. I had to wake the receiver gentle to get her in. It was a perfect fit, any tighter and I would have needed to heat the upper and chill the barrel. It was like they were machined at the same place for a perfect fit. It's a WOA barrel and JD Machine upper/lower. Thanks for the help!
I like anti-seize.
Even with that, you usually have to tap the barrel out.
I use blue loctite as a matter of course these days after I once had an issue with a sloppy fitting barrel which would change poi as it heated up (the receiver face was not quite true, either). Reason I started using the blue is because it was advocated by a top 3 gunner. Contrary to popular belief, heat doesn't really melt it, just breaks it down, but for the purpose of 'bedding' it is fine. In addition, most heating actually occurs further down the barrel, so it doesn't get nearly as hot as many think.
I have also removed said barrels - all it takes is securing the barrel and then tapping off the receiver with a rubber mallet. No need to use high temp red etc unless you want to make extra work for yourself come barrel removal time.
