View Full Version : question about Tucker style conversion!

When a scope has a Tucker type conversion. In this case the scope has two nylon screws one for windage one for elevation. When these conversions are done are the original springs and internal parts left and the screws are in addition too the original works?

Should there be any concern for the screws backing out during a match?
It almost seems like a jam nut on the screw going into the scope body wouldn't be a bad idea.
The one in question seems to take little effort to loosen the nylon screw when I turn it
Thanks

That is not a tucker conversion. That is what some people did back in the locked up scope craze to lock the tube. The thought with the nylon screws was they would kinda be sticky and not move during vibration

So was it common practice to leave the springs and original parts then add the screws?
Or are the screws all there is to hold the tube?

Yes all they did was drill and tap for the screws. A tucker conversion looks like leupold did it- it was a spring under a cap that you didnt have to mess with to adjust your scope

That's what I hoped the screws were. I hoped they were in addition too what was already in place.

Thanks

That was a mod a few did to lock the scopes without permanently gluing them

What dusty said.
A true Tucker Conversion has the factory erector tube tension spring removed and a coil spring installed opposite the turrets. He also cut a small groove on the eye piece side of the erector tube mount and installed a thin O-ring to stabilize it in the scope body.

The March Scope sort of ended the locked scope with external adjustable mounts. That is, except for one shooter, possibly the best Benchrest Shooter on the Planet at this time.
