got a bubbad enfield for free, the stock was really bad but after and hour of steaming dents i refinished it and it looks great. Now the problem... it had a scope mount on it and when i took it off to put a new rear sight assembly on it(which im looking to buy if you have a spare) i realized bubba had taken a grinder to "sides" of where the front of the sight lays(excuse my ignorance) 
so what do I do here, will it still work or should i weld some on then fit and reblue?
