question on bedding the barrel extension into the upper

[Old Bob]

I had an Wilson Combat barrel in a BCA side charge upper that was bedded with Loctite 620. I wanted to move that barrel to a PF upper. With the upper mounted in a vice block, I inserted a 1" diameter dowel from the rear of the upper & smacked it with a large rubber mallet. The barrel popped right out. I think that 620 Loctite kinda breaks like glass when it sets. Give it a good whack & it'll break loose. You could also warm it up a little with a propane/butane torch before you give it a smack.

The 620 residue on the barrel extension & inside the upper pretty much just peeled right off.
