Marine Magnum Scope Mount Recommendations?

[SpyGuy]

Can anyone recommend a good scope mount for a Remington 870 Marine Magnum--one that does not require gunsmithing or permanent modification to the firearm?

Thanks.

I believe B-square makes a mount that uses the two trigger guard assembly pin holes. The pins are replaced with screws that hold the saddle type mount securely. My buddy has one on his Mossberg pump and he likes it, although I question his need for a scope on a home defense shotgun.
