Home Forums Hunting & Shooting Hunting Optics Leica ER Target Turret Fix - DIY w/Pics

As many have pointed out, the Leica ER scopes are absolutely brilliant optically. But the models with target turrets fall short in that the turrets are too easy to turn and aren't tactile enough, at least for my liking. So I dug into a 3.5-14x42 and have found a few little tricks, that at least for me, helped enormously.

This is what the ER TT looks like:



Get started by unscrewing the slotted retaining screw atop the TT. This will allow you to remove finger turret and you'll be looking at this:



The next piece you'll need to remove is what I'll call the mid-cap. This is the piece that you loosen and spin when setting your scope turrets to zero. It's held on with two tiny hex screws. Loosen them and lift the mid-cap up and off the scope. At this point you'll have this view:



Take note of the small silver button/plunger on the front side of the surface that you have just exposed.



There is a tiny spring underneath this plunger. So be careful not to lose the plunger or the spring. Lift the plunger and the spring that fits inside the plunger, out of the scope to a work surface.

*At the heart the mushy turret is the little spring. A much stiffer little spring would solve the issue. And since I didn't have, or go buy, a stiffer spring...I worked with what I had on hand.



I've found a couple of things that help out the soft turret situation that exists...

I shoved a couple of tiny bits of flannel patch down into the hole in which the spring sits. This just shortens the working range of the spring and creates more upward force of the plunger when seated atop the more greatly compressed spring. While I was at it, I pulled the spring a bit to lengthen it, but the tiny bits of patch in the hole seem to do more during my time of trial and error.

It's now time to reassemble. Be sure that your filler underneath the spring is at the bottom of the hole. If it sat up the sides of the spring within the hole, I couldn't get the mid-cap to "re-seat" as it is supposed to.

And one more thing that helped... When the mid-cap is placed back on, push down rather firmly on the top of the mid-cap and snug the hex screws. This packs the spring more tightly against your filler (on the bottom) and the plunger (on its top), and then the plunger is more firmly engaged against the bottom of the mid-cap.

Then just put the top back on and, if your experience is the same as mine, you'll have a much more desirable TT with regard to its field function. Good luck. If anything, this is just overly simple, but it worked for me.

Good info.

It would be nice if someone could come up with a similar fix to tighten up the Leupold CDS.

Was just sitting here trying to figure out how to tighten the turrets on my Leica too. Was considering selling it and going a different direction before now.
