    Be aware the barrels may be TOO thin to safely drill and tap and then secure the scope mount it self

    I wanted to do the same but with a standard contour 12 ga NEF barrel. The gunsmith wouldn't drill and tap. I decided to silver solder the base on. I've test fired it about a dozen times with the gun strapped to a saw horse. Using 2 3/4" max dram loads I haven't been able to see any cracks so far. As advised it was a bit difficult to silver solder with MAPP gas so using acetylene would make it much easier.

    Don't even consider JB Weld for the job. I can see that now that with the recoil a 10 ga or 12 ga can produce the scope could eventually fly off.

    The manufacturer say no to drilling and tapping.

    Where, on the barrel did you silver solder?
