Slip on front sight base options for cut down barrels, available in Canada?

[saskgunowner101]

Was reading another post about someone replacing their front sight on a Mosin, and got me wondering. I have a Swedish Mauser with a cut down barrel (24.5", about .690-.695 diameter), and wondering where in Canada to even look for a front sight option. Obviously the part with the dovetail is gone, so I'm needing a slip on option. Where should I be looking? Thanks in advance.
