I need to swap the foresight block from the scrap M1886 Mannlicher barrel on the right to the nearly complete rifle on the left. I have tried giving it a good blast with a blowtorch and then hitting it from the side with a large pin punch, but move it would not. Is it likely to have been brazed on and I don’t have a hot enough heat source? I could in theory try to cut the barrel out from under it, but that’s not an elegant solution.

Grateful for any suggestions or help.

Cheers,
Mark
