Fastfire 3 vs SpeedBead for Winchester SX3

[jdavenp3]

Which would you choose and why? I have never had any experience with the SpeedBead and have a little concern about the reflex being so close on the gun. However, I would need to drill and tap my Sx3 plus add a mount for the FastFire 3...

Has anyone used both? Any pros/cons either way? I believe both are close to $250 on OpticsPlanet but I would need to add $75ish to get the gun drilled/tapped and a mount added in for the FastFire 3.

If you plan to use the same gun for upland game or water fowl I would go with Speedbead.  If it's only a turkey rig then drill and tap for the Burris marlin mount.
