Barrel removal tool - proof of concept

[montana]

I have removed more Permatex 24300 bedded barrels from their uppers than I can remember, yet I have only had to wiggle the barrel to take them apart. The hardest upper barrel removal I have had was a ""cerekoted out side barrel extension- inside upper receiver barrel channel" that took a great deal of wiggling, but it did come apart. Heat was never used.
