I had read that and considered it. I actually started off by heating up the gas block with a heat gun, but the outcome of that was that I got the gas block closer to the journal but then it locked up well before getting in position and I had to apply substantial force (read "he hit it with a hammer") to get the gas block back off. Ultimately, I suspect that I'll be taking this gas block back off to swap handguards in the future so I wanted to set myself up for success in that endeavor. So, I'm pretty happy with the path I chose, especially since there are no signs of gas leakage around the gas block which was my biggest concern. As an added benefit, I garnered some more experience in the realm of fitting gas blocks. :)
