Opinions on mounting a Vortex Venom or Burris Fastfire on a Mossberg 835....One piece Weaver style base or use one of the shorter two piece base pieces? To me, four screws are tougher than two, but both of these sights are under 2 ounces and shouldn't generate much shear force????? Using one of the two piece bases should be about the same size as the sight base and leave the rest of the receiver clean.
I recently put a Vortex Venom on my 835 and used a Weaver one piece mount. Seems to work fine.
Burris FF 336 mount works really nice on the Mossbergs .
