I do not know anything about the Spartan. I can honestly say that I never heard of it.

The Mossberg 835 is an excellent shotgun. One thing that no one mentioned yet. If you shoot 3 1/2 inch turkey loads, be prepared to have your head kicked off. The first one I shot brought blood to two of my knuckles. I was using an oak tree to steady the shotgun on a paper target. I had my knuckles against the bark, and it brought the blood.

To lessen the recoil go with a gas operated semi, or be "PREPARED". Tom.
