Yes, I have a Vortex Venom mounted on a Meadow Creek rail mount. I never shot it without the red dot but it did not take long to zero it in with the Vortex Venom and it shoots dead on where you place that dot. Be aware that the 20ga does not come drilled and taped like the 12ga SBE3 and Benelli does not recommend drilling and taping them - thus the rail mount which works great for me.
