With some of the available slug guns on the market reaching out to 100 + yds, I was wondering if a rifle scope could be attached to a shotgun? I've only been able to find one "slug gun" advertised scope available in the 3-9 x 40mm range (Bushnell Banner Model 71-3947). Other slug gun advertised scopes commonly focus on 2-7 x 33mm (Leupold VX-I) or there abouts. I'd like to use the same scope (specs) on my shotgun that I have on my rifle (3-9 x 40mm).

Question: Are the scopes advertised under the slug gun umbrella beefed up to absorb the shock/abuse of a rifled barrel shotgun? OR Are these scopes purely advertised as "slug/shot gun" scopes due to the predetermined optic requirements (50-75yds) of a rifled barrel shotgun?

Thanks for your comments in advance,
MD Piney
