Will the Vortex Venom fit on a Burris Speed Bead without any modifications?
Yes indeed
The studs line up but I believe the Venom will overhang the base slightly in the front- it's minimal but not flush like a FastFire.
they work but the screw in the speed bead is different so you will need to find screw. If you run the normal 336 base or our base the screw is the same. I have not clue why the did the different screw in that mount.
