Actually, several top BR 'smiths and talented tinkerers performed this modification. As Wayne mentioned, the late Ron Hoehn is primarily linked to this mod. It's very simple to do and if you don't want to use the screws to lock the erector, just remove them and plug the holes. I've had several scope with this modification. No problems ever.Thank you for your answers; we thought this wasn't done by a reputable and experienced gunsmith
They did...maybe still do on some. I had a 8-32 Signature with that feature. A spring loaded set screw could be adjusted to bear against the erector tube to lock it in place. In practice, that process would change the zero....you had to lead it a bit before you locked it. The last versions of the Burris HBR scopes, the HBRII, featured the Posi Lock spring but not the set screw.Didn't/doesn't Burris have something like that called Posi-Lock?
Correct. I bought one from Ron in 2005. Ron won the Supershoot that year and I was fortunate enough to win the Hv200I thought Ron Hoehn was doing that on Sightrons at one time.
I'm not convinced this mod fixes anything. I had one done years ago and the scope still wondered. The problem is elsewhere.We got this Leupold from an estate; the turrets are blocked by those Delrin screws but if anybody recognises the 'handicraft', that would be helpful.
Thanks in advance.

Pete, what brands of HBR scopes do you need serviced?I sure wish someone would start fixing older scopes, no longer made, specifically 6X HBR scopes. There are a jillion of them languishing that will no longer hold POI. I have several.

The last scope I sent to them they couldn't fix. It wasn't this model so I will try when I get home in the spring. I also sent it to an independent scope person who couldn't fix it either.Pete, Sightron still services those scopes right here in the good 'ol U.S A.
The erector tube has some kind of a 2 axis pivot at one end having some kind of a "cv joint effect". Should that pivot get some play after huge scope use, no modification at turret level will ever solve the issue.
